VALUABLE WORKS. KNOWLEDGE IS POWER: A VIEW OF THE PRODUCTIVE FORCES OF MODERN SOCIETY, and the Result of Labor, Capital, and Skill. By CHARLES KNIGHT. American edition, with Additions, by DAVID A. WELLS, Editor of "Annual of Scientific Discovery," &c. With numerous Illustrations. 12mo, cloth. $1.25. This work is eminently entitled to be ranked in that class, styled, "BOOKS FOR THE PEOPLE." The author is one of the most popular writers of the day. "Knowledge is Power" treats of those things Which "come home to the business and bosoms" of every man. It is remarkable for its fullness and variety of information, and for the felicity and force with which the author applies his facts to his reasoning. The facts and illustrations are drawn from almost every branch of skilful industry. It is a work which the mechanic and artizan of every description will be sure to read with a RELISH. This is a work of rare merit, and touches many strings of importance with which society is linked together. No work we have ever seen is better calculated to inspire and awaken inventive genius in man than this. Almost every department of human labor is represented, and it contains a large fund of useful information, condensed in a volume, every chapter of which is worth the cost of the book. It would be an act of manifest injustice to the community for any editor to feel an indifference about commending this volume to a reading public.--N.Y. CH. HERALD. The style is admirable, and the book itself is as full of information as an egg is of meat.--JOURNAL. As teachers we know no better remuneration, than for them FIRST to buy this book and diligently read it themselves; SECOND, to teach to their pupils the principles of industrial organization which it contains, and of the facts by which it is illustrated. It is one of the merits of this book that its facts will interest youthful minds and be retained to blossom hereafter into theories of which they are now incapable. THIRD, endeavor to have a copy procured for the district library, that the parents may read it, and the teachers reap fruit in the present generation.--N.Y. TEACHER. Contains a great amount of information, accompanied with numerous illustrations, rendering it a compendious history of the subjects upon which it treats.--N.Y. COURIER AND INQUIRER. We commend the work as one of real value and profitable reading.--ROCHESTER AMERICAN. This work is a rich repository of valuable information on various subjects, having a bearing on the industrial end social interests of a community.--PURITAN RECORDER. MY SCHOOLS AND SCHOOLMASTERS; OR, THE STORY OF MY EDUCATION. BY HUGH MILLER, author of "Old Red Sandstone," "Footprints of the Creator," "My First Impressions of England," etc. 12mo, cloth. $1.25. "This autobiography is quite worthy of the renowned author. His first attempts at literature, and his career until he stood forth an acknowledged power among the philosophers and ecclesiastical leaders of his native land, are given without egotism, with a power and vivacity which are equally truthful and delightsome."--PRESBYTERIAN. "Hugh Miller is one of the most remarkable men of the age. Having risen from the humble walks of life, and from the employment of a stone-cutter, to the highest rank among scientific men, everything relating to his history possesses an interest which belongs to that of few living men. There is much even in his school-boy days which points to the man as he now is. The book has all the ease and graphic power which in characteristic of his writings."--NEW YORK OBSERVER. "This volume is a book for the ten thousand. It is embellished with an admirable likeness of Hugh Miller, the stone mason--his coat off and his sleeves rolled up--with the implements of labor in hand--his form erect, and his eye bright and piercing. The biography of such a man will interest every reader. It is a living thing--teaching a lesson of self-culture of immense value."--PHILADELPHIA CHRISTIAN OBSERVER. "It is a portion of autobiography exquisitely told. He is a living proof that a single man may contain within himself something more than all the books in the world, some unuttered word, if he will look within and read. This is one of the best books we have had of late, and must have a hearty welcome and a large circulation in America."--LONDON CORRESP. N.Y. TRIBUNE. "It is a work of rare interest; at times having the fascination of a romance, and again suggesting the profoundest views of education and of science. The ex-mason holds a graphic pen; a quiet humor runs through his pages; he tells a story well, and some of his pictures of home life might almost be classed with Wilson's."--NEW YORK INDEPENDENT. "This autobiography is THE book for poor boys, and others who are struggling with poverty and limited advantages; and perhaps it is not too much to predict that in a few years it will become one of the poor man's classics, filling a space on his scanty shelf next to the Autobiography of Franklin."--NEW ENGLAND FARMER. "Lovers of the romantic should not neglect the book, as it contains a narrative of tender passion and happily reciprocated affection, which will be read with subdued emotion and unfailing interest."--BOSTON TRAVELLER. * * * * * [Illustration: SPHENOPTERIS AFFINIS.

MY DEAR SIR, This volume is chiefly taken up in answering, to the best of its author's knowledge and ability, the various questions which the old theology of Scotland has been asking for the last few years of the newest of the sciences. Will you pardon me the liberty I take in dedicating it to you? In compliance with the peculiar demand of the time, that what a man knows of science or of art he should freely communicate to his neighbors, we took the field nearly together as popular lecturers, and have at least so far resembled each other in our measure of success, that the same class of censors have been severe upon both. For while you have been condemned as a physiologist for asserting that the human framework, when fairly wrought during the week, is greatly the better for the rest of the Sabbath, I have been described by the same pen as one of the wretched class of persons who teach that geology, rightly understood, does not conflict with revelation. Besides, I owe it to your kindness that, when set aside by the indisposition which renders it doubtful whether I shall ever again address a popular audience, you enabled me creditably to fulfil one of my engagements by reading for me in public two of the following discourses, and by doing them an amount of justice on that occasion which could never have been done them by their author. Further, your kind attentions and advice during the crisis of my illness were certainly every way suited to remind me of those so gratefully acknowledged by the wit of the last century, when he bethought him of "kind Arbuthnot's aid, Who knew his art, but not his trade." And so, though the old style of dedication has been long out of fashion, I avail myself of the opportunity it affords me of expressing my entire concurrence in your physiological views, my heartfelt gratitude for your good services and friendship, and my sincere respect for the disinterested part you have taken in the important work of elevating and informing your humbler countryfolk,--while at the same time maintaining professionally, with Simpson and with Goodsir, the reputation of that school of anatomy and medicine for which the Scottish capital has been long so famous. I am, MY DEAR SIR, With sincere respect and regard, Yours affectionately, HUGH MILLER. TO THE READER. Of the twelve following Lectures, four (the First, Second, Fifth, and Sixth) were delivered before the members of the Edinburgh Philosophical Institution (1852 and 1855). One (the Third) was read at Exeter Hall before the Young Men's Christian Association (1854), and the substance of two of the others (the Eleventh and Twelfth) at Glasgow, before the Geological Section of the British Association (1855). Of the five others,--written mainly to complete and impart a character of unity to the volume of which they form a part,--only three (the Fourth, Seventh, and Eighth) were addressed viva voce to popular audiences. The Third Lecture was published both in this country and America, and translated into some of the Continental languages. The rest now appear in print for the first time. Though their writer has had certainly no reason to complain of the measure of favor with which the read or spoken ones have been received, they are perhaps all better adapted for perusal in the closet than for delivery in the public hall or lecture-room; while the two concluding Lectures are mayhap suited to interest only geologists who, having already acquainted themselves with the generally ascertained facts of their science, are curious to cultivate a further knowledge with such new facts as in the course of discovery are from time to time added to the common fund. In such of the following Lectures as deal with but the established geologic phenomena, and owe whatever little merit they may possess to the inferences drawn from these, or on the conclusions based upon them, most of the figured illustrations, though not all, will be recognized as familiar: in the two concluding Lectures, on the contrary, they will be found to be almost entirely new. They are contributions, representative of the patient gleanings of years, to the geologic records of Scotland; and exhibit, in a more or less perfect state, no inconsiderable portion of all the forms yet detected in the rocks of her earlier Palæozoic and Secondary floras. It will be seen that I adopt, in my Third and Fourth Lectures, that scheme of reconciliation between the Geologic and Mosaic Records which accepts the six days of creation as vastly extended periods; and I have been reminded by a somewhat captious critic that I once held a very different view, and twitted with what he terms inconsistency. I certainly did once believe with Chalmers and with Buckland that the six days were simply natural days of twenty-four hours each,--that they had compressed the entire work of the existing creation,--and that the latest of the geologic ages was separated by a great chaotic gap from our own. My labors at the time as a practical geologist had been very much restricted to the Palæozoic and Secondary rocks, more especially to the Old Red and Carboniferous Systems of the one division, and the Oolitic System of the other; and the long extinct organisms which I found in them certainly did not conflict with the view of Chalmers. All I found necessary at the time to the work of reconciliation was some scheme that would permit me to assign to the earth a high antiquity, and to regard it as the scene of many succeeding creations. During the last nine years, however, I have spent a few weeks every autumn in exploring the later formations, and acquainting myself with their peculiar organisms. I have traced them upwards from the raised beaches and old coast lines of the human period, to the brick clays, Clyde beds, and drift and boulder deposits of the Pleistocene era, and again from these, with the help of museums and collections, up through the mammaliferous crag of England, to its Red and its Coral crags. And the conclusion at which I have been compelled to arrive is, that for many long ages ere man was ushered into being, not a few of his humbler contemporaries of the fields and woods enjoyed life in their present haunts, and that for thousands of years anterior to even their appearance, many of the existing molluscs lived in our seas. That day during which the present creation came into being, and in which God, when he had made "the beast of the earth after his kind, and the cattle after their kind," at length terminated the work by moulding a creature in his own image, to whom he gave dominion over them all, was not a brief period of a few hours' duration, but extended over mayhap millenniums of centuries. No blank chaotic gap of death and darkness separated the creation to which man belongs from that of the old extinct elephant, hippopotamus, and hyæna; for familiar animals such as the red deer, the roe, the fox, the wild cat, and the badger, lived throughout the period which connected their times with our own; and so I have been compelled to hold, that the days of creation were not natural, but prophetic days, and stretched far back into the bygone eternity. After in some degree committing myself to the other side, I have yielded to evidence which I found it impossible to resist; and such in this matter has been my inconsistency,--an inconsistency of which the world has furnished examples in all the sciences, and will, I trust, in its onward progress, continue to furnish many more.

To die He longed, nor feared to meet the great "I AM." Fret not. God's mystery is solved to him. He quarried Truth all rough-hewn from the earth, And chiselled it into a perfect gem-- A rounded Absolute. Twain at a birth-- Science with a celestial halo crowned, And Heavenly Truth--God's Works by His Word illumed-- These twain he viewed in holiest concord bound. Reason outsoared itself. His mind consumed By its volcanic fire, and frantic driven, He dreamed himself in hell and woke in heaven. EDINBURGH, December, 1856. MEMORIALS OF THE DEATH AND CHARACTER OF HUGH MILLER, WITH AN ACCOUNT OF HIS FUNERAL OBSEQUIES. Near the end of last autumn the American publishers of Hugh Miller's works received from him, through his Edinburgh publishers, the offer of a new work from his pen. The offer was accepted and a contract was at once closed. Soon the advance sheets began to come; and as successive portions were received and perused, it became more and more evident that the work was destined not only to extend his fame, but to establish for him new and special claims to the admiration and gratitude of mankind. In the midst of these anticipations, and ere more than half the sheets had been received, the publishers and the public here were startled by the news that Mr. Miller had come to a violent death. The paragraph conveying the intelligence was such as to leave the mind in a state of painful suspense. But the next steamer from Europe brought full details of the lamentable event. It appeared that in a momentary fit of mental aberration he had died by his own hand, on the night of December 23d, 1856. The cause was over much brain-work. He had been long and incessantly engaged in preparing the present work for the press, when, just as he had given the last touches to the eloquent, the immortal record, reason abandoned her throne, and in the brief interregnum, that great light of science was quenched forever. The event caused universal lamentation throughout the British Isles. It was treated as a public calamity. The British press, from the _London Times_ to the remotest provincial newspaper, gave expression to the general sorrow in strains of unwonted eloquence; and in so doing recounted his great services to the cause of science, and paid homage to his genius. Some of the articles which the event thus called forth have seemed to the American publishers worthy of preservation, from the authentic facts which they embody, the judgments which they express, and the literary excellence by which they are marked. They have therefore determined to print them in connection with this work as permanent Memorials of its distinguished and lamented author. The first piece appeared in the _Edinburgh Witness_ of December 27th, 1856,--the paper of which Mr. Miller had been the editor from its establishment in 1840. It presents an authentic account of the circumstances attending his death, and is understood to be from the pen of the REV. WILLIAM HANNA, L.L.D., the son-in-law and biographer of Dr. Chalmers, and sometime editor of the _North British Review_. In the belief that nothing touching the character and memory of such a man can be regarded with other than the deepest interest, the friends of Mr. Hugh Miller have thought it due at once to his great name and to the cause of truth, to lay fully before the public a statement of the most mournful circumstances under which he has departed from this life. For some months past his over-tasked intellect had given evidence of disorder. He became the prey of false or exaggerated alarms. He fancied--if, indeed, it was a fancy--that occasionally, and for brief intervals, his faculties quite failed him,--that his mind broke down. He was engaged at this time with a treatise on the "Testimony of the Rocks," upon which he was putting out all his strength,--working at his top-most pitch of intensity. That volume will in a few weeks be in the hands of many of our readers; and while they peruse it with the saddened impression that his intellect and genius poured out their latest treasures in its composition, they will search through it in vain for the slightest evidence of feebleness or decaying power. Rather let us anticipate the general verdict that will be pronounced upon it, and speak of it as one of the ablest of all his writings. But he wrought at it too eagerly. Hours after midnight the light was seen to glimmer through the window of that room which within the same eventful week was to witness the close of the volume, and the close of the writer's life. This over-working of the brain began to tell upon his mental health. He had always been somewhat moodily apprehensive of being attacked by footpads, and had carried loaded firearms about his person. Latterly, having occasion sometimes to return to Portobello from Edinburgh at unseasonable hours, he had furnished himself with a revolver. But now, to all his old fears as to attacks upon his person, there was added an exciting and over-mastering impression that his house, and especially that Museum, the fruit of so much care, which was contained in a separate outer building, were exposed to the assault of burglars. He read all the recent stories of house robberies. He believed that one night, lately, an actual attempt to break in upon his Museum had been made. Visions of ticket-of-leave men, prowling about his premises, haunted him by day and by night. The revolver, which lay nightly near him, was not enough; a broad-bladed dagger was kept beside it; whilst behind him, at his bed head, a claymore stood ready at hand. A week or so ago, a new and more aggravated feature of cerebral disorder showed itself in sudden and singular sensations in his head. They came only after lengthened intervals. They did not last long, but were intensely violent. The terrible idea that his brain was deeply and hopelessly diseased,--that his mind was on the verge of ruin,--took hold of him, and stood out before his eye in all that appalling magnitude in which such an imagination as his alone could picture it. It was mostly at night that these wild paroxysms of the brain visited him; but up till last Monday he had spoken of them to no one. A friend who had a long conversation with him on the Thursday of last week, never enjoyed an interview more, or remembers him in a more genial mood. On the Saturday forenoon another friend from Edinburgh found him in the same happy frame. As was his wont when with an old friend with whom he felt particularly at ease, he read or recited some favorite passages, repeating, on this occasion, with great emphasis, that noble prayer of John Knox,[1] which, he told his friend, it had been his frequent custom to repeat privately during the days of the Disruption. On the forenoon of Sunday last he worshipped in the Free Church at Portobello; and in the evening read a little work which had been put into his hands, penning that brief notice of it which will be read with melancholy interest as his last contribution to this journal. About ten o'clock on Monday morning he took what with him was an altogether unusual step. He called on Dr. Balfour, in Portobello, to consult him as to his state of health. "On my asking," says Dr. Balfour, in a communication with which we have been favored, "what was the matter with him, he replied, 'My brain is giving way. I cannot put two thoughts together to-day. I have had a dreadful night of it; I cannot face another such. I was impressed with the idea that my Museum was attacked by robbers, and that I had got up, put on my clothes, and gone out with a loaded pistol to shoot them. Immediately after that I became unconscious. How long that continued, I cannot say; but when I awoke in the morning I was trembling all over, and quite confused in my brain. On rising I felt as if a stiletto was suddenly, and as quickly as an electric shock, passed through my brain from front to back, and left a burning sensation on the top of the brain just below the bone. So thoroughly convinced was I that I must have been out through the night, that I examined my trousers to see if they were wet or covered with mud, but could find none.' He further said,--'I may state that I was somewhat similarly affected through the night twice last week, and I examined my trousers in the morning to see if I had been out. Still the terrible sensations were not nearly so bad as they were last night; and I may further inform you, that towards the end of last week, while passing through the Exchange in Edinburgh, I was seized with such a giddiness that I staggered, and would, I think, have fallen, had I not gone into an entry, where I leaned against the wall, and became quite unconscious for some seconds.'" Dr. Balfour stated his opinion of the case; told him that he was over-working his brain, and agreed to call on him on the following day to make a fuller examination. Meanwhile the quick eye of affection had noticed that there was something wrong, and on Monday forenoon Mrs. Miller came up to Edinburgh to express her anxiety to Professor Miller, and request that he would see her husband. "I arranged," says Professor Miller, "to meet Dr. Balfour at Shrub Mount (Mr. Hugh Miller's house), on the afternoon of next day. We met accordingly at half-past three on Tuesday. He was a little annoyed at Mrs. Miller's having given me the trouble, as he called it, but received me quite in his ordinary kind, friendly manner. We examined his chest and found that unusually well; but soon we discovered that it was head symptoms that made him uneasy. He acknowledged having been, night after night, up till very late in the morning, working hard and continuously at his new book, 'which,' with much satisfaction, he said, 'I have finished this day.' He was sensible that his head had suffered in consequence, as evidenced in two ways: first, occasionally he felt as if a very fine poignard had been suddenly passed through and through his brain. The pain was intense, and momentarily followed by confusion and giddiness, and the sense of being 'very drunk,'--unable to stand or walk. He thought that a period of unconsciousness must have followed this,--a kind of swoon,--but he had never fallen. Second, what annoyed him most, however, was a kind of nightmare, which for some nights past had rendered sleep most miserable. It was no dream, he said; he saw no distinct vision, and could remember nothing of what had passed accurately. It was a sense of vague and yet intense horror, with a conviction of being abroad in the night wind, and dragged through places as if by some invisible power. 'Last night,' he said, 'I felt as if I had been ridden by a witch for fifty miles, and rose far more wearied in mind and body than when I lay down.' So strong was his conviction of having been out, that he had difficulty in persuading himself to the contrary, by carefully examining his clothes in the morning, to see if they were not wet or dirty; and he looked inquiringly and anxiously to his wife, asking if she was sure he had not been out last night, and walking in this disturbed trance or dream. His pulse was quiet, but tongue foul. The head was not hot, but he could not say it was free from pain. But I need not enter into professional details. Suffice it to say that we came to the conclusion that he was suffering from an over-worked mind, disordering his digestive organs, enervating his whole frame, and threatening serious head affection. We told him this, and enjoined absolute discontinuance of work, bed at eleven, light supper (he had all his life made that a principal meal), thinning the hair of the head, a warm sponging-bath at bed time, &c. To all our commands he readily promised obedience, not forgetting the discontinuance of neck rubbing, to which he had unfortunately been prevailed to submit some days before. For fully an hour we talked together on these and other subjects, and I left him with no apprehension of impending evil, and little doubting but that a short time of rest and regimen would restore him to his wonted vigor." It was a cheerful hour that thus was passed, and his wife and family partook of the hopeful feeling with which his kind friend, Professor Miller, had parted with him. It was now near the dinner hour, and the servant entered the room to spread the table. She found Mr. Miller in the room alone. Another of the paroxysms was on him. His face was such a picture of horror that she shrunk in terror from the sight. He flung himself on the sofa, and buried his head, as if in agony, upon the cushion. Again, however, the vision flitted by, and left him in perfect health. The evening was spent quietly with his family. During tea he employed himself in reading aloud Cowper's "Castaway," the Sonnet on Mary Unwin, and one of his more playful pieces, for the special pleasure of his children. Having corrected some proofs of the forthcoming volume, he went up stairs to his study. At the appointed hour he had taken the bath, but unfortunately his natural and peculiar repugnance to physic had induced him to leave untaken the medicine that had been prescribed. He had retired into his sleeping-room,--a small apartment opening out of his study, and which, for some time past, in consideration of the delicate state of his wife's health, and the irregularity of his own hours of study, he occupied at night alone,--and lain sometime upon the bed. The horrible trance, more horrible than ever, must have returned. All that can now be known of what followed is to be gathered from the facts, that next morning his body, half dressed, was found lying lifeless on the floor, the feet upon the study rug, the chest pierced with the ball of the revolver pistol, which was found lying in the bath that stood close by.[2] The deadly bullet had perforated the left lung, grazed the heart, cut through the pulmonary artery at its root, and lodged in the rib in the right side. Death must have been instantaneous. The servant by whom the body was first discovered, acting with singular discretion, gave no alarm, but went instantly in search of the doctor and minister; and on the latter the melancholy duty was devolved of breaking the fearful intelligence to that now broken-hearted widow, over whose bitter Borrow it becomes us to draw the veil. The body was lifted and laid upon the bed. We saw it there a few hours afterwards. The head lay back sideways on the pillow. There was the massive brow, the firm-set, manly features, we had so often looked upon admiringly, just as we had lately seen them,--no touch nor trace upon them of disease,--nothing but that overspread pallor of death to distinguish them from what they had been. But the expression of that countenance in death will live in our memory forever. Death by gunshot wounds is said to leave no trace of suffering behind; and never was there a face of the dead freer from all shadow of pain, or grief, or conflict, than that of our dear departed friend. And as we bent over it, and remembered the troubled look it sometimes had in life, and thought what must have been the sublimely terrific expression that it wore at the moment when the fatal deed was done, we could not help thinking that it lay there to tell us, in that expression of unruffled, majestic repose that sat upon every feature, what we so assuredly believe, that the spirit had passed through a terrible tornado, in which reason had been broken down; but that it had made the great passage in safety, and stood looking back to us, in humble, grateful triumph, from the other side. On looking round the room in which the body had been discovered, a folio sheet of paper was seen lying on the table. On the centre of the page the following lines were written,--the last which that pen was ever to trace:-- "DEAREST LYDIA,--My brain burns. I _must_ have _walked_; and a fearful dream rises upon me. I cannot bear the horrible thought. God and Father of the Lord Jesus Christ have mercy upon me. Dearest Lydia, dear children, farewell. My brain burns as the recollection grows. My dear, dear wife, farewell." HUGH MILLER. What a legacy of love to a broken-hearted family! and to us, and all who loved him, how pleasing to observe, that in that bewildering hour, when the horror of that great darkness came down upon that noble spirit, and some hideous, shapeless phantom overpowered it, and took from it even the capacity to discern the right from the wrong, humility, and faith, and affection, still kept their hold;--amid the ruins of the intellect, that tender heart remaining still unbroken! These last lines remain as the surest evidence of the mysterious power that laid his spirit prostrate, and of the noble elements of which that spirit was composed,--humble, and reverent, and loving to the last. Yesterday, at the request of friends, and under the authority of the Procurator-Fiscal, a _post mortem_ examination of the body took place. We subjoin the result:-- "EDINBURGH, December 26, 1856. "We hereby certify, on soul and conscience, that we have this day examined the body of Mr. Hugh Miller, at Shrub Mount, Portobello. "The cause of death we found to be a pistol-shot through the left side of the chest; and this, we are satisfied, was inflicted by his own hand. "From the diseased appearances found in the brain, taken in connection with the history of the case, we have no doubt that the act was suicidal under the impulse of insanity." JAMES MILLER, W.T. GAIRDNER, A.H. BALFOUR, A.M. EDWARDS. We must ask to be excused from attempting any analysis of Mr. Miller's character and genius, or any estimate of the distinguished services he has rendered to literature, science, and the Christian faith. His loss is too heavy a one,--his removal has come upon us too suddenly and too awfully for mind or hand to be steady enough for such a task. The voice of the public press has already told what a place he had won for himself in the admiration and affection of his countrymen; and for the delicate and tender way in which the manner of his departure has universally been alluded to, were we permitted to speak in the name of Mr. Miller's friends, we should express our deepest gratitude. It is a beautiful and worthy tribute that his brother journalists have rendered to the memory of one who was a laborer along with them in elevating the talent and tone of our newspaper literature. As Free Churchmen, however, it would be unpardonable were we to omit all reference, at such a time as this, to what he did on behalf of the church of his adoption. Dr. Chalmers did not err when, self-oblivious, he spake of Mr. Miller, as he so often did, as the greatest Scotchman alive after Sir Walter Scott's death, and as the man who had done more than all others to defend and make popular throughout the country the non-intrusion cause. We know well what the mutual love and veneration was of those two great men for one another whilst living; and now that both are gone,--and hereafter we believe still more so than even now,--their two names will be intertwined in the grateful and admiring remembrance of the ministers and members of the Free Church. It was die high honor of the writer of these hurried lines to record the part taken by his venerated relative in that great ecclesiastical struggle which terminated in the Disruption. At that lime it was matter to him of great regret that, as his office was that of the biographer, and not of the historian, there did not occur those natural opportunities of speaking of the part taken by Mr. Miller in that struggle, of which he gladly would have availed himself. And he almost wishes now that he had violated what appeared to him to be his duty, in order to create such an opportunity. He feels as if in this he had done some injustice to the dead,--an injustice which it would gratify him beyond measure if he could now in any way repair, by expressing it as his own judgment, and the judgment of the vast body of his Church, that, next to the writings and actings of Dr. Chalmers, the leading articles of Mr. Miller in this journal did more than anything else to give the Free Church the place it holds in the affections of so many of our fellow-countrymen. But Mr. Miller was far more than a Free Churchman, and did for the Christianity of his country and the world a far higher service than any which in that simple character and office was rendered by him. There was nothing in him of the spirit and temper of the sectarian. He breathed too broad an atmosphere to live and move within such narrow bounds. In the heat of the conflict there may have been too much occasionally of the partisan; and in the pleasure that the sweep and stroke of his intellectual tomahawk gave to him who wielded it, he may have forgotten at times the pain inflicted where it fell; but let his writings before and after the Disruption be now consulted, and it will be found that it was mainly because of his firm belief, whether right or wrong, that the interests of vital godliness were wrapped up in it, that he took his stand, and played his conspicuous part, in the ecclesiastical conflict. It is well known that for some time past,--for reasons to which it would be altogether unseasonable to allude,--he has ceased to take any active part in ecclesiastical affairs. He had retired even, in a great measure, from the field of general literature, to devote himself to the study of Geology. His past labors in this department,--enough to give him a high and honored place among its most distinguished cultivators,--he looked upon but as his training for the great life-work he had marked out for himself,--the full investigation and illustration of the Geology of Scotland. He had large materials already collected for this work; and it was his intention, after completing that volume which has happily been left in so finished a state, to set himself to their arrangement. The friends of science in many lands will mourn over the incompleted project which, however ably it may hereafter be accomplished by another, it were vain to hope shall ever be so accomplished as it should have been by one who united in himself the power of accurate observation, of logical deduction, of broad generalization, and of pictorial and poetic representation. But the friends of Christianity cannot regret, that since it was the mysterious decree of Heaven that he should prematurely fall,--his work as a pure Geologist not half done,--he should have been led aside by the publication of the Vestiges of Creation to that track of semi-theological, semi-scientific research to which his later studies and later writings have been devoted. That, as it now seems to us, was the great work which it was given him on earth to do,--to illustrate the perfect harmony of all that science tells us of the physical structure and history of our globe, with all that the Bible tells of the creation and government of this earth by and through Christ Jesus our Lord. The establishment and exhibition of that harmony was a task to which is it too much to say that there was no man living so competent as he? We leave it to the future to declare how much he has done by his writings to fulfil that task; but mourning, as we now can only do, over his sad and melancholy death,--to that very death, with all the tragic circumstances that surround it, we would point as the closing sacrifice offered on the altar of our faith. His very intellect, his reason,--God's most precious gift,--a gift dearer than life,--perished in the great endeavor to harmonize the works and word of the Eternal. A most inscrutable event, that such an intellect should have been suffered to go to wreck through too eager a prosecution of such a work. But amid the mystery, which we cannot penetrate, our love, and our veneration, and our gratitude, toward that so highly gifted and truly Christian man shall only grow the deeper because of the cloud and the whirlwind in which he has been borne off from our side. On the 31st of December, two days after the obsequies had been performed, Dr. Hanna resumed the subject in the following elevated strain: We have still but little heart to dilate on any political or literary topic. Our thoughts can dwell on but one thrice melancholy event. Need we name that event? Alas, no! It had occurred but a few hours when the tidings of it struck our city with stunning, stupefying, and deeply saddening blow. It has already thrilled our whole land; and is on its way, through a hundred channels, to the west, to the east, and to the south, carrying with it mourning and lamentation throughout the vast area which is covered by the language in which Hugh Miller wrote. Writing, as it were, amid the deep shadows of the funeral chamber, and brought in a manner into the very presence of the dead, we are made strongly to feel, and we daresay our readers to a large extent will feel, too, the nothingness of those discussions which usually occupy and engross men. The weightiest matter that ever occupied the wisdom of cabinet or the pen of journalist appears verily but fleeting and transitory, when brought thus into prominent contrast with the awful realities of human existence and destiny; and it is only when reflection shows us that these matters are yet parts of a grand Providential scheme, embracing man's happiness now, and entering deeply into the question of his future and eternal well-being, that we can see in them that amount of significance and importance which they really possess. From the firmament of British literature and science a great light has departed. But yesterday we rejoiced in its beams, and now it has set all suddenly and forever; and to us there remains but the melancholy task of bewailing its departure, and tracing very hastily and imperfectly its track. The intellectual powers of Hugh Miller had certainly not declined. He was marked to the very last by that wonderful robustness of mind which had characterized him all through life. His sense was as manly, his judgment as sound and comprehensive, his penetration as discriminating and deep, his imagination as vigorous and bold, and his taste as pure and trusty, as they had ever been. The whole of his great powers were found working together up to the last week of his earthly career, with their usually calm, noiseless strength, and finely balanced and exquisitely toned harmony. We have evidence of this fact under his own hand in recent numbers of the _Witness_. His last two articles were, the one on Russia, and the other on our modern poets. The former,--that on the resources of the Russian empire,--is characterized by the same wide range of thinking, the same skill in analysis, and the same power of grouping and arranging details, and making them to throw light on some great principle, which usually marked and notified his hand when employed on such subjects. The latter,--that on the poets,--is rich and genial as usual, betokening a full and unclouded recollection of all his early reading in that department of our literature, abounding in the finest touches of pathos and beauty, and redolent with a most generous sympathy with kindred genius. It is not inconsistent with what we have now stated, and it is the fact, that latterly the inroads of disease, which had entrenched itself deeply in a constitution originally strong, and which kept steadily advancing upon the vital powers, had come so near the seat of the mind, that for short intervals the noble spirit was sadly beclouded, and its moral and intellectual action momentarily suspended. But, apart from this, there seemed ground to believe that there was yet before Mr. Miller much honorable and noble labor. The strong man, after all his tasks, appeared to be still strong. His powers were mellowing into richness and calm, matured strength; his conceptions of great principles were growing yet wider; his store of facts, literary as well as scientific, was accumulating with every busy and laborious year that passed over him; and there did seem ground to expect from his pen, unrivalled among his contemporaries in its exquisite purity and calm power, many a deep thoughted article, and many a profoundly reasoned and richly illustrated volume. We looked to him for the solution of many a dark question in science; and we certainly hoped, from that fine union of science and theology which dwelt in him above all men, for a yet fuller and more complete adjustment of the two great records of Creation,--that of the Rocks, and that of Moses. But alas! all these hopes have suddenly failed us. It seemed right otherwise to the Great Disposer of all. He has said to his faithful servant, "Enough." Let us look back upon that work. We by no means aim at giving a calm, well weighed, and deeply pondered estimate of it, but only such a glance as the circumstances permit and require. His great and special work was his advocacy of the principles of the Free Church. Mr. Miller was _par excellence_ the popular expounder and defender of these principles, whether in their embryotic state in the Non-Intrusion party, or as embodied in the fully developed and completely emancipated Free Protesting Church of Scotland. For this service, in connection with which he would have best liked to be remembered, as he best deserved it, he had unconsciously been undergoing a course of preparation even when a boy. He himself has told us with what eagerness he devoured, at that period of life, the legendary histories of Wallace and Bruce; and the occupation had its use. It gave him a capacity for admiring what was great though perilous in exploit, and for truly and largely sympathizing with what was patriotic and self-sacrificing in character; and so it created a groundwork for his own future thinking and acting. The admiration he then bore to these earliest of our "Scottish Worthies," who vindicated on Bannockburn, and kindred fields, Scotland's right to be an independent and free country, he afterwards transferred to our later "Worthies," whom he revered as greater still. Not that he ever lost his admiration of the former, or ceased to value the incalculable services they rendered to the Scottish nation; but that he regarded Knox and Melville as men occupying a yet higher platform,--as gifted with a yet deeper insight into their country's wants,--as, in short, carrying forward and consummating the glorious task which Wallace and Bruce had but begun. He saw that unless our reformers had come after our heroes, planting schools, founding colleges, and, above all, imparting to their countrymen a scriptural and rational faith, in vain had Bruce unsheathed his sword,--in vain had Wallace laid down his life. Wallace and Bruce had created an independent country; Knox and Melville had created an independent people. They were the creators of the Scottish nation,--the real enfranchisers of our people; and it was this that taught Mr. Miller to venerate these men so profoundly, and that made him in his inmost soul a devoted follower, and to the utmost extent of his great faculties a defender, of their cause. He was a soldier from love,--pure, heroic, chivalrous devotion soaring infinitely above the partisan. He saw that the Church of Scotland was the creator of the rights and privileges of the people of Scotland,--that she was the grand palladium of the country's liberties,--that while she stood an independent and free institution, the people stood an independent and free nation,--and that bonds to her meant slavery to them. Therefore did he gird on the sword when he saw peril gathering around her. The privileges,--the entire standing of the common people, as given them by the Reformation,--he saw to be in danger: he was "one of themselves;" and he felt and fought as if almost the quarrel had been a personal one, and the question at issue his own liberty or slavery. How richly equipped and nobly armed he came into the field, we need not here state. What fulness yet precision of ecclesiastical lore,--what strength and conclusiveness of argument,--what flashes of humor, wit, and sarcasm,--and in what a luminous yet profoundly philosophical light did he set the great principles involved in the controversy, making them patent in the very cottages of our land, and so fixing them in the understandings of the very humblest of our people, that they never afterwards could be either misunderstood or forgotten! It was thus that the way was prepared for the great result of the 18th of May, 1843. Of Mr. Miller, as a man of science and a public journalist, we cannot speak at present at any length. In him the love of science was deeply seated and early developed. The first arena on which he appeared--obscure and humble as it was--afforded him special opportunities of initiating himself into what to him was then, and continued ever afterwards to be, a most fascinating study. The study of geology was eagerly prosecuted amid the multifarious duties, and during the brief pauses, of a busy life. Several original discoveries rewarded his patient and laborious investigations. He succeeded at length in placing his name in the first rank of British scientific thinkers and writers. His works are characterized by a fine union of strict science, classic diction, and enchanting description, which rises not unfrequently into the loftiest vein of poetry. The fruits of his researches were ever made to bear upon the defence and elucidation of the Oracles of Truth. Our common Christianity owes much to his pen. Viewing him as a journalist, Mr. Miller not only excelled in article writing,--the most difficult of all kinds of composition,--but, as will be generally admitted, he has introduced a new era into newspaper writing. If the moral tone of our newspaper press is higher now than it was twenty-five years ago, we have Mr. Miller in large degree to thank for it; and to him, too, is to be traced that purer style and more philosophic spirit which begins to be discernible in the columns of our public journals. But the character in which his personal friends will deplore him most, and will most frequently recall his memory, will be that of the man. How meek and gentle he was!--how unpretending and modest, even as a very child!--how true and steady in friendship!--how wise and playful his mirth!--how ripened and chastened his wisdom!--how ready to counsel!--how willing to oblige!--how generous and large his sympathies! No little jealousies, no fretful envyings, had he! Even in opposition, how noble and manly was he: if a powerful, he was a fair and open antagonist; and whatever hard blows were dealt, they were dealt in his own journal. We have seen him in various moods and in all circumstances; but never did we hear him utter an unkind or disparaging word of man. He was, too, a sincere and humble Christian; and the lively faith which he cherished in the adorable Redeemer and his all-efficacious sacrifice, bore abundantly its good fruits in a life including no ordinary variety of condition and trial, and running on to such term as to make abundantly manifest what manner of man he was. The article which follows is from the _Edinburgh News_. It is evidently from the pen of one who was intimately acquainted with Hugh Miller, and is worthy of attention, not only for its eloquent and discriminating notices of his works, but also for its statements respecting his great designs, never, alas, to be accomplished. It is not many months since we chronicled the death of the greatest of living Scotsmen, and the prince of modern philosophers--Sir William Hamilton. These last few days have bereft us of another of our countrymen not less illustrious, and known all over the world as one of the princes of geology. We cannot well estimate the loss which society sustains in the death of Mr. Miller. He occupied a foremost place among us, and there is none on whom his mantle can fall. In the world of letters his name takes high rank, for undoubtedly he was one of the ablest writers in our literature. Who can have read without delight his manly, vigorous language, soaring sometimes into the highest eloquence, anon plunging into the depths of metaphysical argument, or grappling with the dry technicalities of science, yet ever rolling along with the same easy, onward flow? His style has all the charm of Goldsmith's sweetness, with the infusion of a rich vigor that gives it an air of great originality. He is one of the few writers who have successfully conjoined the graces of literature with the formal details of science, and whose works are perused for their literary excellences, independently altogether of their scientific merit. His writings will ever be regarded among the classics of the English language. For obvious reasons we pass over his editorial labors. It is on the republic of science that his death will fall most heavily. There can be little doubt that he has done more to popularize his favorite department than any other writer. Of all geological works, his enjoy, perhaps, the widest circulation--not in this country, merely, but all over the world, and especially in the United States. His reputation, however, does not rest solely on his standing as an exponent of science to the people; he was himself an original and accurate observer. When the infant science of geology was battling for existence against the opposing phalanx of united Christendom, Hugh Miller, then a mere lad, was quietly working as a stone-mason in the north of Scotland, and employing his leisure time among the fossil fishes of the Old Red Sandstone, and the ammonites and the belemnites of the Lias, that abound in the neighborhood of Cromarty. As years rolled slowly away, he continued his observations, and when at length, in 1841, the results were given to the world in his well known "Old Red Sandstone," every one was charmed with the novelty and beauty of the style, and his reputation as a writer was at once established. Men of science, however, though acknowledging the graphic and elegant diction of his descriptions, had some doubts as to their truthfulness. Indeed, by some geologists they were cast aside as fanciful, and other restorations of the Old Red fishes were proposed and adopted. Those who are acquainted with Old Red ichthyolites, or who have had the pleasure of examining the exquisite series in Mr. Miller's collection, may well smile at the absurdity of the restorations that were adopted. Yet some of these found their way into a work of no little popularity,--Mantell's "Medals of Creation." It is sufficient to state that the drawings there given bear no resemblance to anything in the heavens above or on the earth beneath, or in the waters under the earth, nor to any fossil organism that has ever been discovered. At length the progress of investigation led to the discarding of these monstrosities, and Miller's restorations were returned to, as, after all, the true ones. "The Old Red Sandstone" formed an era in the history of fossil geology. That formation had hitherto been regarded as well nigh barren of organic remains; but Mr. Miller demonstrated that it contains at least three successive stages, each characterized by a suite of uncouth and hitherto unknown fishes. A few years later he published his "Footprints of the Creator." This is undoubtedly his _chef-d'oeuvre_, exhibiting, as it does, the full powers of his massive intellect and his poetic imagination. As a piece of scientific investigation and research, it is of a very high order; as a reply to the crudities of the development theory, it is unanswerable; and as a contribution to our physico-theological literature, it ranks, with Chalmers' "Astronomical Lectures," among the finest in this or any other language. Some of the ideas are as profound as they are original, opening up a new field of thought, which it was doubtless the intention of the deceased himself to cultivate. His published works, however, contain but a fraction, of the labors of his lifetime. For many years past he has been, one of the most energetic members of the Royal Physical Society, at whose meetings he from time to time made known the progress of his researches. Were these papers collected, they would form several goodly volumes. But their author studiously refrained from publishing them, save occasionally in the columns of the _Witness_ newspaper. It was his intention that they should each form a part of the great work of his life, to which for many years his leisure moments had been devoted. His design was to combine the results of all his labors among the different rock formations of Scotland into one grand picture of the geological history of our country. For this end he had explored a large part of the Scottish counties, anxious that his statements should rest as far as possible upon the authority of his own personal investigations. His knowledge of the geology of the country was thus far more extensive than was generally supposed. We may refer particularly to that branch of it on which he bestowed the unremitted attention of his closing years,--the palæontological history of the glacial beds,--that strange and as yet almost unknown period that ushered in the existing creation. He studied it minutely along the shores of the Moray Firth, on the east coast of Scotland, along the shores of Fife and the Lothians, and on the coast of Ayrshire and the Firth of Clyde. This last summer he made a tour through the centre of the island, and obtained boreal shells at Buchlyvie in Stirlingshire,--the _omphalos_ of Scotland. The importance of this discovery, in connection with those he had previously made in following out the same chain of evidence, can only be appreciated by those who have paid some attention to geology. We may state briefly that it proves the central area of Scotland to have been submerged beneath an icy sea, and icebergs to have grated along over what is now the busy valley of the Forth and Clyde, while the waters were tenanted by shells at present found only in the Northern Ocean. A large part of his work is written, though it is to be feared that much knowledge, amassed in the course of its preparation, has perished with him. In particular, there were whole sections of his Museum understood only by himself. Every little fragment had its story, and contributed its quota of evidence to the truth of his descriptions. There is, perhaps, but another mind in Britain,--that of Sir Philip Egerton,--that can catch up the thread, and read off, though with difficulty, the meaning of those carefully arranged fragments. Yet, even with such aid, much must long, if not forever, remain dark and obscure. The work on which he was more immediately engaged at the time of his death was partly theological, partly scientific. It was to embrace the substance of some lectures lately delivered, and a paper read last year before the British Association at Glasgow on the fossil plants collected by himself from the Oolite and Old Red Sandstone of Scotland. It was likewise to contain the figures of some thirty or forty hitherto undescribed species of vegetables. We hope that, as it was all but ready for publication, it may yet be given to the world. The name of Hugh Miller will ever stand forth as synonymous with all that is honest and manly; as the impersonation of moral courage and indomitable energy; as the true ideal of a self-educated man. From the humblest sphere of life, and from the toils of a stone-mason's apprentice, without means, without friends, without other than the most rudimentary education, he rose, by his own unaided and unwearied exertions, to fill one of the brightest pages in the annals of our country. And when, in future years, an example is sought of unconquerable perseverance, of fearless integrity, and of earnest, ceaseless activity, the voice of universal approbation shall proclaim--"_the stone-mason of Cromurty_." We have spoken of this mournful event only as a public calamity; yet, to those who were personally acquainted with the departed, it is invested with no ordinary sadness. Long, long shall they remember the playful fancy, the rich humor, the warm, genial heart of their friend. His simple, open frankness endeared him to every one, though his retiring disposition prevented him from making many intimate friendships. To those who enjoyed this higher privilege, his death must have caused the most poignant regret. Yet what can even their sorrow be to that of the relatives of the departed? We lament the death of one who was alike an honor to his profession, to literature, to science, and to his country,--one of the most loved and cherished of friends. Let us not forget to mingle our sympathy and our sorrow with that deeper grief that mourns the loss of a husband and a father. As coming from a different quarter, and presenting a somewhat different view, the following, from the _London Literary Gazette_, should have a place here. Hugh Miller was born at Cromarty in 1805. In his early life he worked as a laborer in the Sandstone quarries in his native district, and afterwards as a stone-mason in different parts of Scotland. In a work published in 1854, "My Schools and Schoolmasters, or the story of my Education," Mr. Miller gives a most interesting account of his early history, and of the training and self-culture by which he rose to honorable rank in literature and science. Notwithstanding the unpretending statements of this narrative, and the disavowal of any other elements of success than are within ordinary reach, every reader of that book feels that homage is due to a genius original and rare, as well as to natural talents diligently and judiciously cultivated. While professedly written for the benefit of the working classes of his own country, there are few who may not derive pleasant and profitable lessons from this most remarkable piece of autobiography. After being engaged in manual labor for about fifteen years, Mr. Miller was for some time manager of a bank that was established in his native town. While in this position, a pamphlet that he published, on the ecclesiastical controversies which then distracted Scotland, attracted the attention of the leaders of the party who now form the Free Church, and they invited him to be editor of the _Witness_ newspaper, then about to be established for the advocacy of their principles. Mr. Miller had already published a volume of "Legendary Tales of Cromarty," of which the late Baron Hume, nephew of the historian, himself a man of much judgment and taste, said it was "written in an English style, which he had begun to regard as one of the lost arts." The ability displayed by Mr. Miller as editor of the _Witness_, and the influence exerted by him on ecclesiastical and educational events in Scotland, are well known. Mr. Miller did not confine his newspaper to topics of local or passing interest. In its columns he made public his geological observations and researches; and most of his works originally appeared in the form of articles in that newspaper. It was in 1840, the year at which the autobiographical memoir closes, that the name of Hugh Miller first became widely known beyond his own country. At the meeting of the British Association for the Advancement of Science at Glasgow that year, Sir Roderick, then Mr. Murchison, gave an account of the striking discoveries recently made in the Old Red Sandstone of Scotland. M. Agassiz, who was present, pointed out the peculiarities and the importance of these discoveries; and it was on this occasion that he proposed to associate the name of Mr. Miller with them, by the wonderful fossil, the _Pterichthys Milleri_, specimens of which were then under the notice of the section. Dr. Buckland, following M. Agassiz, said that "he had never been so much astonished in his life by the powers of any man as he had been by the geological descriptions of Mr. Miller. He described these objects with a felicity which made him ashamed of the comparative meagreness and poverty of his own descriptions in the 'Bridgewater Treatise,' which had cost him hours and days of labor. He (Dr. Buckland) _would give his left hand to possess such powers of description as this man_; and if it pleased Providence to spare his useful life, he, if any one, would certainly render the science attractive and popular, and do equal service to theology and geology." At the meetings of the Association, the language of panegyric and of mutual compliment is not unfrequent, and does not signify much; but these were spontaneous tributes of praise to one comparatively unknown. The publication of the volume on the "Old Red Sandstone," with the details of the author's discoveries and researches, more than justified all the anticipations that had been formed. It was received with highest approbation, not by men of science alone, for the interest of its facts, but by men of letters, for the beauty of its style. Sir Roderick Murchison, in his address to the Geological Society that year, "hailed the accession to their science of such a writer," and said that "his work is, to a beginner, worth a thousand didactic treatises." The _Edinburgh Review_ spoke of the book being "as admirable for the clearness of its descriptions, and the sweetness of its composition, as for the purity and gracefulness that pervade it." The impression made by such a testimony was the more marked, that the reviewer spoke of the writer as a fellow countryman, "meritorious and self-taught." In 1847 appeared "First Impressions of England and its People," the result of a tour made during the previous year. Some parts of this book, especially the account of the pilgrimages to Stratford-on-Avon, and the Leasowes, and Olney, and other places memorable for their literary associations, are as fine pieces of descriptive writing as the English language possesses. This magic of style characterized all his works, whether those of a more popular kind, or his scientific treatises, such as the "Old Red Sandstone," and "Footprints of the Creator," a volume suggested by the "Vestiges of Creation," and subversive of the fallacies of that superficial and plausible book. Not one of the authors of our day has approached Hugh Miller as a master of English composition, for the equal of which we must go back to the times of Addison, Hume, and Goldsmith. Other living writers have now a wider celebrity, but they owe it much to the peculiarities of their style or the popularity of their topics. Mr. Miller has taken subjects of science, too often rendered dry and repulsive, and has thrown over them an air of attractive romance. His writings on literature, history, and politics, are known to comparatively few, from having appeared in the columns of a local newspaper. A judicious selection from his miscellaneous articles in the _Witness_ would widely extend his fame, and secure for him a place, in classic English literature, as high as he held during his life as a periodical writer and as a scientific geologist. The personal appearance of Mr. Miller, or "Old Red," as he was familiarly named by his scientific friends, will not be forgotten by any who have seen him. A head of great massiveness, magnified by an abundant profusion of sub-Celtic hair, was set on a body of muscular compactness, but which in later years felt the undermining influence of a life of unusual physical and mental toil. Generally wrapped in a bulky plaid, and with a garb ready for any work, he had the appearance of a shepherd from the Rosshire hills rather than an author and a man of science. In conversation or in lecturing, the man of original genius and cultivated mind at once shone out, and his abundant information and philosophical acuteness were only less remarkable than his amiable disposition, his generous spirit, and his consistent, humble piety. Literature and science have lost in him one of their brightest ornaments, and Scotland one of its greatest men. * * * * * On the Sabbath following Mr. Miller's death, sermons referring to the event were preached in many of the churches in Edinburgh. Some of these were reported in the newspapers, among which may be mentioned those by the Rev. Drs. Hanna, Guthrie, Hetherington, Begg, and Tweedie. On Monday, December the 29th, the Funeral Obsequies were performed. The following account of the imposing ceremonial is from the _Edinburgh Witness_. FUNERAL OF MR. HUGH MILLER. The mortal remains of this truly great man were consigned to the grave on Monday, amid the most marked demonstrations of sorrow on the part of the entire community. The private company, numbering about sixty individuals, met at Shrub Mount, the residence of the deceased at Portobello, about a quarter to one in the afternoon. Amongst those present were the Lord Provost of Edinburgh; A.M. Dunlop, Esq., M.P.; A. Black, Esq., M.P.; Professors Simpson, Balfour, and Fraser; Rev. Principal Cunningham; Professor James Buchanan; Rev. Drs. Guthrie, Candlish, Hanna, Bruce, Begg, Hetherington, and Wylie; Rev. Messrs. M'Kenzie of Dunfermline, Cameron and Hunter of Nagpoor; Maurice Lothian, Esq.; Geo. Dalziell, Esq., W.S.; W. Wood, Esq.; R. Paul, Esq.; Francis Russell, Esq., advocate; M. Torrance, Esq.; Dr. Russell; Dr. Geo. Bell; J.F. Macfarlan, Esq.; Archibald Gibson, Esq.; and Councillor Johnston. The devotional exercises were conducted by Dr. Guthrie, who was deeply affected during the prayer, and whose feelings at times threatened to overcome him. Thirteen two-horse mourning coaches were here in waiting to convey the company to the place of sepulture in the Grange Cemetery, preceded by the hearse, which had four horses. The melancholy event, as might have been expected, cast a gloom over the whole of Portobello; and the Provost and Magistrates, anticipating the general feeling of the inhabitants, to whom Mr. Miller had endeared himself by his genius and the modesty of his demeanor, and also by the readiness which he ever displayed to contribute to their intellectual elevation, by taking part in several courses of popular lectures in the town, recommended the closing of the different shops,--a request which was at once readily complied with. Another striking proof of the general desire to pay the last tribute of respect to the remains of the deceased, was furnished by the circumstance that upwards of one hundred gentlemen, many of whom had, so recently as the previous Tuesday, listened to the reading of one of the ablest of his lectures, by the Rev. Mr. Wight, the Congregational minister, met at half-past twelve in the Free Church, in order to accompany the funeral, either on foot or in carriages, to the burial place,--a distance of about four miles. After a short, impressive religious service, conducted by the Rev. Mr. Philip and the Rev. Mr. Wight, they proceeded to join the private company, who had by this time taken their places in the mourning carriages, on their way to Edinburgh. On reaching the General Post-Office, in Waterloo Place, the ranks of the funeral procession were largely augmented, there being here as many as from twenty to thirty private carriages in waiting, filled with the leading citizens, and a large body of the inhabitants, of all ranks, classes, and denominations, drawn up in line three or four abreast. The Kirk-Session of Free St. John's, of which Mr. Miller was an office-bearer, headed by the Rev. Dr. Guthrie and the Rev. Dr. Hanna, who left the carriage at the Post-Office, occupied the front of the procession, immediately followed by the Royal Physical Society, of which the lamented deceased was a leading member, the _employes_ in the _Witness_ office, and a large body of the general public. A still more numerous body of the citizens, as well as of parties from Glasgow, Liverpool, Stirling, Bridge of Allan, and other parts of the country, drew up in the rear of the long line of carriages, while the sides of the streets were also lined with mourners, who accompanied the procession to the Cemetery. Besides the large concourse of people who here joined the procession, the whole front of the Register Office and the corners of the North Bridge were densely occupied by some thousands of spectators; and it may be safely said, that no event since the death of Dr. Chalmers has caused such deep-felt sorrow and regret in Edinburgh. The numbers present in the funeral _cortege_ must have amounted to from one to two thousand; indeed, one paper states that "at one time there could not have been many less than four thousand people in the procession;" whilst another journal says, that although the inclemency of the weather, the day being one of the dreariest of the season, "kept back many who would otherwise have swelled the line of mourners, even with this drawback, it has been informed that the attendance was even greater than on the occasion of the funeral of Dr. Chalmers in 1847." After a short delay, caused by these accessions to the procession, the whole moved up the North Bridge. It was gratifying to observe that nearly all the shops on the North and South Bridges, and in Nicolson and Clerk streets, along which the _cortege_ passed, were closed; and along the whole route many a saddened countenance and tearful eye could be seen, all testifying to the deep respect entertained for him whose manly form had so often traversed these same streets. On reaching the entrance of the Grange Cemetery, the coffin was removed from the hearse, and borne shoulder high to the tomb, followed by the pall-bearers and the general company. The ground selected for the burial-place is the westmost space but one on the northern side of the Cemetery, and in a line with the graves of Dr. Chalmers, Sir Andrew Agnew, and Sheriff Speirs, with which it is in close proximity. As many of our readers are aware, the situation is one of surpassing scenic beauty, and was described by the deceased's own matchless pen but a few years ago, on the occasion of the burial of Chalmers; and certainly in the grave of Hugh Miller a new feature of attraction has been added to the spot. The pall-bearers were Mr. Miller's oldest son,--a boy about fourteen years of age,--who was accompanied by his younger brother, six or seven years old; Mr. A. Williamson, his half-brother and nearest kinsman; Mr. Fairly, his partner in business; Rev. Dr. Guthrie, Rev. Dr. Hanna, Mr. Dunlop, M.P., Mr. R. Paul, and Principal Cunningham. The mournful ceremony was now near its close. As the heavy, dull sound, caused by the fall of the damp earth upon the coffin, fell upon the ear, a sad and painful sensation crept over the frame, increased as this was by the wintry aspect of the day and the heavy leaden sky, which, like a pall, was spread over the face of nature, in striking harmony with the solemnity of the scene. A few minutes more, and all was over; and the vast company, uncovered, paid the closing mark of respect to the ashes of the mighty dead. A touching scene occurred at the close of all. After the whole of the company had retired, a laboring man, clad in humble habiliments, seized hold of a handful of ivy or laurel leaves, and gently strewed them upon the grave, while the tearful eye eloquently spoke of the strength of his feelings. So passed away one of whom Dr. Chalmers made the remark that "since Scott's death he was the greatest Scotchman that was left." "The space his name occupied in the literary and scientific world," says another, "could hardly have been conjectured, but for the blank he leaves behind him now that he has left it. Other men may have extended the domain of science wider; but no man has done more to extend the circle of its votaries by the magic of his style and the life-like power of his descriptions; nor has any man done more to keep together the claims, too often made to appear divergent, of Science and Religion, and to blend them into one intelligent and reasonable service. It was worth while to have lived to effect this, even at the cost of the clouds which saddened and darkened the close. But ----'glory without end Scatters the clouds away; and on that name attend The thanks and praises of all time.'" A PRAYER BY JOHN KNOX, MADE AT THE FIRST ASSEMBLIE OF THE CONGREGATION, WHEN THE CONFESSION OF OUR FAITHE AND WHOLE ORDERS OF THE CHURCH WAS THERE RED AND APPROVED.[3] O Lord God Almightie, and Father moste mcrcifull, there is none lyke thee in heaven nor in earthe, which workest all thinges for the glorie of thy name and the comfort of thyne elect. Thou dydst once make man ruler over all thy creatures, and placed hym in the garden of all pleasures; but how soone, alas, dyd he in his felicitie forget thy goodness? Thy people Israel also, in their wealth dyd evermore runne astray, abusinge thy manifold mercies; lyke as all fleshe contynually rageth when it hath gotten libertie and external prosperitie. But such is thy wisdome adjoyned to thy mercies, deare Father, that thou sekest all means possible to brynge thy chyldren to the sure sense and lyvely feelinge of thy fatherly favour. And therefore when prosperitie wyll not serve, then sendest thow adversitie, graciously correctinge all thy chyldren whome thou receyvest into thy howshold. Wherfore we, wretched and miserable synners, render unto thee most humble and hartie thankes, that yt hath pleased thee to call us home to thy folde by thy Fatherly correction at this present, wheras in our prosperitie and libertie we dyd neglect thy graces offered unto us. For the which negligence, and many other grevous synnes whereof we now accuse our selves before thee, thow mightest moste justly have gyven us up to reprobate mynds and induration of our hartes, as thow haste done others. But such is thy goodnes, O Lord, that thou semest to forget alt our offences, and haste called us of thy good pleasure from all idolatries into this Citie most Christianlye refourmed, to professe thy name, and to suffer some crosse amongest thy people for thy truth and Gospell's sake; and so to be thy wytnesses with thy Prophets and Apostles, yea, with thy dearely beloved Sonne Jesus Christ our head, to whome thow dost begynne here to fashion us lyke, that in his glorie we may also be lyke hym when he shall appear. O Lord God, what are we upon whome thowe shuldest shewe this great mercye? O moste lovynge Lord, forgyve us our unthankfulnes, and all our synnes, for Jesus Christ's sake. O heavenly Father, increase thy Holy Spirit in us, to teache our heartes to cry Abba, deare Father! to assure us of our eternal election in Christ; to revele thy wyll more and more towards us; to confirme us so in thy trewthe, that we may lyve and dye therein; and that by the power of the same Spirit we may boldlely gyve an accompts of our faith to all men with humblenes and mekenes, that whereas they backbyte and slaunder us as evyll doers, they may be ashamed and once stopp their mowthes, seinge our good conversation in Christ Iesu, for whose sake we beseche thee, O Lord God, to guide, governe, and prosper this our enterprise in assemblinge our bretherne, to prayse thy holie name. And not only to be here present with us thy children according to thy promesse, but also mercifullie to assist thy like persecuted people, our Bretherne, gathered in all other places, that they and we, consentinge together in one spirite and truethe, may (all worldly respectes set a part) seke thy onely honor and glorie in all our and their Assemblies. SO BE IT. THE TESTIMONY OF THE ROCKS. LECTURE FIRST. THE PALÆONTOLOGICAL HISTORY OF PLANTS. Palæontology, or the science of ancient organisms, deals, as its subject, with all the plants and animals of all the geologic periods. It bears nearly the same sort of relation to the _physical_ history of the past, that biography does to the civil and political history of the past. For just as a complete biographic system would include every name known to the historian, a complete palæontologic system would include every fossil known to the geologist. It enumerates and describes all the organic existences of all the extinct creations,--all the existences, too, of the present creation that occur in the fossil or semi-fossil form; and, thus coextensive in space with the earth's surface,--nay, greatly more than coextensive with the earth's surface,--for in the vast hieroglyphic record which our globe composes, page lies beneath page, and inscription covers over inscription,--coextensive, too, in time, with every period in the terrestrial history since being first began upon our planet,--it presents to the student a theme so vast and multifarious, that it might seem but the result, on his part, of a proper modesty, conscious of the limited range of his powers, and of the brief and fleeting term of his life, were he to despair of being ever able effectually to grapple with it. "But," to borrow from one of the most ingenious of our Scottish metaphysicians, "in this, as in other instances in which nature has given us difficulties with which to cope, she has not left us to be wholly overcome." "If," says Dr. Thomas Brown, in his remarks on the classifying principle,--"if she has placed us in a labyrinth, she has at the same time furnished us with a clue which may guide us, not, indeed, through all its dark and intricate windings, but through those broad paths which conduct us into day. The single power by which we discover resemblance or relation in general, is a sufficient aid to us in the perplexity or confusion of our first attempts at arrangement. It begins by converting thousands, and more than thousands, into one; and, reducing in the same manner the numbers thus formed, it arrives at last at the few distinctive characters of those great comprehensive tribes on which it ceases to operate, because there is nothing left to oppress the memory or the understanding." But, is this all? Can the Palæontologist but say that that classifying principle, which in every other department of science yields such assistance to the memory, is also of use in his, or but urge that it enables him to sort and arrange his facts; and that, by converting one idea into the type and exemplar of many resembling ones, it imparts to him an ability of carrying not inadequate conceptions of the mighty whole in his mind? If this were all, you might well ask, Why obtrude upon us, in connection with your special science, a common semi-metaphysical idea, equally applicable to all the sciences,--in especial, for example, to that botany which is the science of existing plants, and to that zoology which is the science of existing animals? Nay, I reply, but it is not all. I refer to this classifying principle because, while it exists in relation to all other sciences as a principle--to use the words of the metaphysician just quoted--"given to us by nature,"--as a principle of _the mind within_,--it exists in Palæontological science as a principle of nature itself,--as a principle palpably _external to the mind_. It is a marvellous fact, whose full meaning we can as yet but imperfectly comprehend, that myriads of ages ere there existed a human mind, well nigh the same principles of classification now developed by man's intellect in our better treatises of zoology and botany, were developed on this earth by the successive geologic periods; and that the by-past productions of our planet, animal and vegetable, were chronologically arranged in its history, according to the same laws of thought which impart regularity and order to the works of the later naturalist and phytologists. I need scarce say how slow and interrupted in both provinces the course of arrangement has been, or how often succeeding writers have had to undo what their predecessors had done, only to have their own classifications set aside by _their_ successors in turn. At length, however, when the work appears to be well nigh completed, a new science has arisen, which presents us with a very wonderful means of testing it. Cowley, in his too eulogistic ode to Hobbes,--smit by the singular ingenuity of the philosophic infidel, and unable to look through his sophisms to the consequences which they involved,--could say, in addressing him, that "only God could know Whether the fair idea he did show Agreed entirely with God's own or no." And he then not very wisely added,-- "This, I dare boldly tell, 'T is so like truth, 't will serve our turn as well." We now know, however, that no mere resemblance to truth will for any considerable length of time serve its turn. It is because the resemblances have, like those of Hobbes, been mere resemblances, that so much time and labor have had to be wasted by the pioneers of science in their removal; and, now that a wonderful opportunity has occurred of comparing, in this matter of classification, the human with the Divine idea,--the idea embodied by the zoologists and botanists in their respective systems, with the idea embodied by the Creator of all in geologic history,--we cannot perhaps do better, in entering upon our subject, than to glance briefly at the great features in which God's order of classification, as developed in Palæontology, agrees with the order in which man has at length learned to range the living productions, plant and animal, by which he is surrounded, and of which he himself forms the most remarkable portion. In an age in which a class of writers not without their influence in the world of letters would fain repudiate every argument derived from _design_, and denounce all who hold with Paley and Chalmers as anthropomorphists, that labor to create for themselves a god of their own type and form, it may be not altogether unprofitable to contemplate the wonderful parallelism which exists between the Divine and human systems of classification, and--remembering that the geologists who have discovered the one had no hand in assisting the naturalists and phytologists who framed the other--soberly to inquire whether we have not a new argument in the fact for an identity in constitution and quality of the Divine and human minds,--not a mere fanciful identity, the result of a disposition on the part of man to imagine to himself a God bearing his own likeness, but an identity real and actual, and the result of that creative act by which God formed man in his own image. The study of plants and animals seems to have been a favorite one with thoughtful men in every age of the world. According to the Psalmist, these great "works of the Lord are sought out of all them that have pleasure therein." The Book of Job, probably the oldest writing in existence, is full of vivid descriptions of the wild denizens of the flood and desert; and it is expressly recorded of the wise old king, that he "spake of trees, from the cedar tree that is in Lebanon, even unto the hyssop that springeth out of the wall; and also of beasts, and of fowl, and of creeping things, and of fishes." Solomon was a zoologist and botanist; and there is palpable classification in the manner in which his studies are described. It is a law of the human mind, as has been already said, that, wherever a large stock of facts are acquired, the classifying principle steps in to arrange them. "Even the rudest wanderer in the fields," says Dr. Brown, "finds that the profusion of blossoms around him--in the greater number of which he is able himself to discover many striking resemblances--may be reduced to some order of arrangement." But, for many centuries, this arranging faculty labored but to little purpose. As specimens of the strange classification that continued to obtain down till comparatively modern times, let us select that of two works which, from the literary celebrity of their authors, still possess a classical standing in letters,--Cowley's "Treatise on Plants," and Goldsmith's "History of the Earth and Animated Nature." The plants we find arranged by the poet on the simple but very inadequate principle of size and show. Herbs are placed first, as lowest and least conspicuous in the scale; then flowers; and, finally, trees. Among the herbs, at least two of the ferns--the true maidenhair and the spleenwort--are assigned places among plants of such high standing as sage, mint, and rosemary: among the flowers, monocotyledons, such as the iris, the tulip, and the lily, appear among dicotyledons, such as the rose, the violet, the sunflower, and the auricula: and among trees we find the palms placed between the plum and the olive; and the yew, the fir, and the juniper, flanked on one side by the box and the holly, and on the other by the oak. Such, in treating of plants, was the classification adopted by one of the most learned of English poets in the year 1657. Nor was Goldsmith,-who wrote more than a century later, much more fortunate in dealing with the animal kingdom. Buffon had already published his great work; and even he could bethink him of no better mode of dividing his animals than into wild and tame. And in Goldsmith, who adopted, in treating of the mammals, a similar principle, we find the fishes and molluscs placed, in advance of the sauroid, ophidian, and batrachian reptiles,--the whale united in close relationship to the sharks and rays,--animals of the tortoise kind classed among animals of the lobster kind, and both among shell fish, such as the snail, the nautilus, and the oyster. And yet Goldsmith was engaged on his work little more than eighty years ago. In fine, the true principles of classification in the animal kingdom are of well nigh as recent development as geologic science itself, and not greatly more ancient in even the _vegetable_ kingdom. It would, of course, be wholly out of place to attempt giving a minute history here of the progress of arrangement in either department; but it can scarce be held that the natural system of plants was other than very incomplete previous to 1789, when Jussieu first enunciated his scheme of classification; nor did it receive its later improvements until so late as 1846, when, after the publication, in succession, of the schemes of De Candolle and Endlicher, Lindley communicated his finished system to the world. And there certainly existed no even tolerably perfect system of zoology until 1816, when the "Animal Kingdom" of Cuvier appeared. Later naturalists,--such as Agassiz, in his own special department, the history of fishes, and Professor Owen in the invertebrate divisions,--have improved on the classification of even the great Frenchman; but for purposes of comparison between the scheme developed in geologic history and that at length elaborated by the human mind, the system of Cuvier will be found, for at least our present purpose, sufficiently complete. And in tracing through time the course of the vegetable kingdom, let us adopt, as our standard to measure it by, the system of Lindley. Commencing at the bottom of the scale, we find the Thallogens, or flowerless plants which lack proper stems and leaves,--a class which includes all the algæ. Next succeed the Acrogens, or flowerless plants that possess both stems and leaves,--such as the ferns and their allies. Next, omitting an inconspicuous class, represented by but a few parasitical plants incapable of preservation as fossils, come the Endogens,--monocotyledonous flowering plants, that include the palms, the liliaceæ, and several other families, all characterized by the parallel venation of their leaves. Next, omitting another inconspicuous tribe, there follows a very important class,--the Gymnogens,--polycotyledonous trees, represented by the conifers; and cycadaceæ. And, last of all, come the Dicotyledonous Exogens,--a class to which all our fruit, and what are known as our "forest trees," belong, with a vastly preponderating majority of the herbs and flowers that impart fertility and beauty to our gardens and meadows. This last class, though but one, now occupies much greater space in the vegetable kingdom than all the others united. Such is the arrangement of Lindley, or rather an arrangement the slow growth of ages, to which this distinguished botanist has given the last finishing touches. And let us now mark how closely it resembles the geologic arrangement as developed in the successive stages of the earth's history. [Illustration: Fig. 1.[4] -+------------------------- | Thallogens.

THE GENEALOGY OF PLANTS.] The most ancient period of whose organisms any trace remains in the rocks seems to have been, prevailingly at least, a period of Thallogens. We must, of course, take into account the fact, that it has yielded no land plants, and that the sea is everywhere now, as of old, the great habitat of the algæ,--one of the four great orders into which the Thallogens are divided. There appear no traces of a terrestrial vegetation until we reach the uppermost beds of the Upper Silurian System. But, account for the fact as we may, it is at least worthy of notice, that, alike in the systems of our botanists and in the chronological arrangements of our geologists, the first or introductory class which occurs in the ascending order is this humble Thallogenic class. There is some trace in the Lower Silurians of Scotland of a vegetable structure which may have belonged to one of the humbler Endogens, of which, at least, a single genus, the _Zosteraceæ,_ still exists in salt water; but the trace is faint and doubtful, and, even were it established, it would form merely a solitary exception to the general evidence that the first known period of vegetable existence was a period of Thallogens. The terrestrial remains of the Upper Silurians of England, the oldest yet known, consist chiefly of spore-like bodies, which belonged, says Dr. Hooker, to Lycopodiaceæ,--an order of the second or acrogenic class. And, in the second great geologic period,--that of the Old Red Sandstone,--we find this second class not inadequately represented. In its lowest fossiliferous beds we detect a Lycopodite which not a little resembles one of the commonest of our club mosses,--_Lycopodium clavatum_,--with a minute fern and a large striated plant resembling a calamite, and evidently allied to an existing genus of Acrogens, the equisetaceæ. In the Middle Old Red Sandstone there also occurs a small fern, with some trace of a larger; and one of its best preserved vegetable organisms is a lepidodendron,--an extinct ally of the Lycopodiums; while in the upper beds of the system, especially as developed in the south of Ireland, the noble fern known as _Cyclopteris Hibernicus_ is very abundant. This fern has been detected also in the Upper Old Red of our own country, mingled with fragments of contemporary calamites. With, however, these earliest plants of the land yet known, there occurs a true wood, which belonged, as shown by its structure, to a gymnospermous or polycotyledonous tree, and which we find associated with remains of Coccosteus and Diplacanthus. [Illustration: Fig. 2. CYCLOPTERIS HIBERNICUS. (Nat. size.)] [Illustration: Fig. 3. CONIFER OF THE LOWER OLD RED SANDSTONE. Cromarty. (Mag. forty diameters.)] And here let me remark, that the facts of Palæontological science compel us to blend, in some degree, with the classification of our modern botanists, that of the botanists of an earlier time. In a passage already quoted, Solomon is said to have discoursed of plants, "from the cedar tree that is in Lebanon, to the hyssop that springeth out of the wall,"--from the great tree to the minute herb; and Cowley rose, in his metrical treatise, as has been shown, from descriptions of herbs and flowers to descriptions of fruit and forest trees. And as in every age in which there existed a terrestrial vegetation there seem to have been "trees" as certainly as "herbs," the palæontological botantist finds that he has, in consequence, to range his classes, not in one series, but in two,--the Gymnogens, or cone-bearing trees, in a line nearly parallel with the Acrogens, or flowerless, spore-bearing herbs. But the arrangement is in no degree the less striking from the circumstance that it is ranged, not in one, but in two lines. It is, however, an untoward arrangement for the purposes of the Lamarckian, whose peculiar hypothesis would imperatively demand, not a double, but a single column, in which the ferns and club mosses would stand far in advance, in point of time, of the Coniferæ. In the Coal Measures, so remarkable for the great luxuriance of their flora, both the Gymnogens and Acrogens are largely developed, with a very puzzling intermediate class, that, while they attained to the size of trees, like the former, retained in a remarkable degree, as in the Lepidodendra and the Calamites, the peculiar features of the latter. And with these there appear, though more sparingly, the Endogens,--monocotyledonous plants, represented by a few palm-like trees (Palmacites), a few date-like fruits (Trigonocarpum), and a few grass-like herbs (Poacites). In the great Secondary division, the true dicotyledonous plants first appear; but, so far as is yet known, no dicotyledonous wood. In the earlier formations of the division a degree of doubt attaches to even the few leaves of this class hitherto detected; but in the Lower Cretaceous strata they become at once unequivocal in their character, and comparatively abundant, both as individuals and species; and in the Tertiary deposits they greatly outnumber all the humbler classes, and appear not only as herbs, but also as great trees. Not, however, until shortly before the introduction of man do some of their highest orders, such as the Rosaceæ, come upon the scene, as plants of that great garden--including the fields of the agriculturist--which it has been part of man's set task upon earth to keep and to dress. And such seems to be the order of classification in the vegetable kingdom, as developed in creation, and determined by the geologic periods.

THE GENEALOGY OF ANIMALS.] The parallelism which exists between the course of creation, as exhibited in the animal kingdom, and the classification of the greatest zoologist of modern times, is perhaps still more remarkable. Cuvier divides all animals into vertebrate and invertebrate; the invertebrates consisting, according to his arrangement, of three great divisions,--mollusca, articulata, and radiata; and the vertebrates, of four great classes,--the mammals, the birds, the reptiles, and the fishes. From the lowest zone at which organic remains occur, up till the higher beds of the Lower Silurian System, all the animal remains yet found belong to the invertebrate divisions. The numerous tables of stone which compose the leaves of this first and earliest of the geologic volumes correspond in their contents with that concluding volume of Cuvier's great work in which he deals with the mollusca, articulata, and radiata; with, however, this difference, that the three great divisions, instead of occurring in a continnous series, are ranged, like the terrestrial herbs and trees, in parallel columns. The chain of animal being on its first appearance is, if I may so express myself, a threefold chain;--a fact nicely correspondent with the further fact, that we cannot in the present creation range _serially_, as either higher or lower in the scale, at least two of these divisions,--the mollusca and articulata. In one of the higher beds of the Upper Silurian System,--a bed which borders on the base of the Old Red Sandstone,--the vertebrates make their earliest appearance in their fourth or ichthyic class; and we find ourselves in that volume of the geologic record which corresponds to Cuvier's volume on the fishes. In the many-folded pages of the Old Red Sandstone, till we reach the highest and last, there occur the remains of no other vertebrates than those of this fourth class; but in its uppermost deposits there appear traces of the third or reptilian class; and in passing upwards still, through the Carboniferous, Permian, and Triassic Systems, we find reptiles continuing the master existences of the time. The geologic volume in which these great formations are included corresponds to the Cuvierian one devoted to the Reptilia. Early in the Oolitic System, birds, Cuvier's second class of the vertebrata, make their first appearance, though their remains, like those of birds in the present time, are rare and infrequent; and, for at least the earlier periods of their existence, we know that they were,--that they haunted for food the waters of the period, and waded in their shallows,--only from marks similar to those by which Crusoe became first aware of the visits paid to his island by his savage neighbors,--their footprints, left impressed on the sands over which they stalked of old. This early Oolitic volume corresponds in its contents to the section devoted by Cuvier, in his great work, to his second class, the birds. And in the Stonisfield slate,--a deposit interposed between the "Inferior" and "Great Oolites," we detect the earliest indications of his first or mammaliferous class, apparently represented, however, by but one order,--the Marsupiata, or pouched animals, to whose special place in the scale I shall afterwards have occasion to refer. Not until we reach the times of the Tertiary division do the mammals in their higher orders appear. The great Tertiary volume corresponds to those volumes of Cuvier which treat of the placental animals that suckle their young. And finally,--last born of creation,--man appears upon the scene, in his several races and varieties; the sublime arch of animal being at length receives its keystone; and the finished work stands up complete, from foundation to pinnacle, at once an admirably adjusted occupant of space, and a wonderful monument of Divine arrangement and classification, as it exists in time. Save at two special points, to which I shall afterwards advert, the particular arrangement unfolded by geologic history is exactly that which the greatest and most philosophic of the naturalists had, just previous to its discovery, originated and adopted as most conformable to nature: the arrangements of geologic history as exhibited in time, if, commencing at the earliest ages, we pursue it downwards, is exactly that of the "Animal Kingdom" of Cuvier read backwards. Let us then, in grappling with the vast multiplicity of our subject, attempt reducing and simplifying it by means of the classifying principle; not simply, however,--again to recur to the remark of the metaphysician,--as an internal principle given us by nature, but as an external principle _exemplified_ by nature. Let us take the organisms of the old geologic periods in the order in which they occur in time; secure, as has been shown, that if our chronology be correct, our classification will, as a consequence, be good. It will be for the natural theologians of the coming age to show the bearing of this wonderful fact on the progress of man towards the just and the solid, and on the being and character of man's Creator,--to establish, on the one hand, against the undue depreciators of intellect and its results, that in certain departments of mind, such as that which deals with the arrangement and development of the scheme of organic being, human thought is not profitlessly revolving in an idle circle, but progressing Godwards, and gradually unlocking the order of creation. And, on the other hand, it will be equally his proper business to demand of the Pantheist how,--seeing that only _persons_ (such as the Cuviers and Lindleys) could have wrought out for themselves the real arrangement of this scheme,--how, I say, or on what principle, it is to be held that it was a scheme originated and established at the beginning, not by a _personal_, but by an impersonal God. But our present business is with the _fact_ of the parallel arrangements, Divine and human,--not with the inferences legitimately deducible from it. [Illustration: Fig. 5. OLDHAMIA ANTIQUA;--the oldest known Zoophyte. Wrae Head, Ireland.] [Illustration: Fig. 6. PALÆOCHORDA MINOR. (One half nat. size.)] Beginning with the plants, let us, however, remark, that they do not precede in the order of their appearance the humbler animals. No more ancient organism than the _Oldhamia_ of the Lowest Irish Silurians, a plant-like zoophyte somewhat resembling our modern sertularia, has yet been detected by the geologist; though only a few months ago the researches of Mr. Salter in the ancient rocks of the Longmynd, Shropshire, previously deemed unfossiliferous, have given, to it what seem to be contemporary vegetable organisms, in a few ill-preserved fucoids. So far as is yet known, plants and animals appear together. The long upward march of the animal kingdom takes its departure at its starting point from a thick forest of algæ. In Bohemia, in Norway, in Sweden, in the British Islands, in North America, wherever, in fine, what appears to be the lowest, or at least one of the lowest, zones of life has yet been detected, the rocks are found to be darkened by the remains of algæ, so abundantly developed in some cases, that they compose, as in the ancient Lower Silurians of Dumfriesshire, impure beds of anthracite several feet in thickness. Apparently, from the original looseness of their texture, the individual plants are but indifferently preserved; nor can we expect that organisms so ancient should exhibit any _very_ close resemblance to the plants which darken the half-tide rocks and skerries of our coasts at the present time. We do detect, however, in some of these primordial fossils, at least a noticeable likeness to families familiar to the modern algæologist. The cord-like plant, _Chorda filum_, known to our children as "dead men's ropes," from its proving fatal at times to the too adventurous swimmer who gets entangled in its thick wreaths, had a Lower Silurian representative, known to the Palæontologist as the _Palæochorda_, or ancient chorda, which existed apparently in two species,--a larger and smaller. The still better known _Chondrus crispus_, the Irish moss or carrageen of our cookery-books, has likewise its apparent though more distant representative in _Chondritis_, a Lower Silurian algæ, of which there seems to exist at least three species. The fucoids, or kelp weeds, appear to have had also their representatives in such plants as _Fucoides gracilis_ of the Lower Silurians of the Malverns; in short, the Thallogens of the first ages of vegetable life seem to have resembled, in the group, and in at least their more prominent features, the algæ of the existing time. And with the first indications of land we pass direct from the Thallogens to the Acrogens,--from the sea weeds to the fern allies. The Lycopodiaceæ;, or club mosses, bear in the axils of their leaves minute circular cases, which form the receptacles of their spore-like seeds. And when, high in the Upper Silurian System, and just when preparing to quit it for the Lower Old Red Sandstone, we detect our earliest terrestrial organisms, we find that they are composed exclusively of those little spore receptacles. The number of land plants gradually increases as we ascend into the overlying system. Still, however, the Flora of even the Old Red is but meagre and poor; and you will perhaps permit me to lighten this part of my subject, which threatens too palpably to partake of the poverty of that with which it deals, by a simple illustration. [Illustration: Fig. 7. LYCOPODIUM CLAVATUM.] [Illustration: Fig. 8. EQUISETUM FLUVIATILE.] We stand, at low ebb, on the outer edge of one of those iron-bound shores of the Western Highlands, rich in forests of algæ, from which, not yet a generation bygone, our Celtic proprietors used to derive a larger portion of their revenues than from their fields and moors. Rock and skerry are brown with sea weed. The long cylindrical lines of _Chorda filum_, many feet in length, lie aslant in the tideway; long shaggy bunches of _Fucus serratus_ and _Fucus nodosus_ droop heavily from the rock sides; while the flatter ledges, that form the uneven floor upon which we tread, bristle thick with the stiff, cartilaginous, many-cleft fronds of at least two species of chondrus,--the common carrageen, and the smaller species, _C. Norvegicus_. Now, in the thickly-spread fucoids of this Highland shore we have not a _very_ inadequate representation of the first, or thallogenic vegetation,--that of the great Silurian period, as exhibited in the rocks, from the base to nearly the top of the system. And should we add to the rocky tract, rich in fucoids, a submarine meadow of pale shell sand, covered by a deep green swathe of zostera, with its jointed saccharine roots and slim flowers, unfurnished with petals, we would render it perhaps more adequately representative still. [Illustration: Fig. 9. OSMUNDA REGALIS. (Royal Fern.)] We cross the beach, and enter on a bare brown moor, comparatively fertile, however, in the club mosses. One of the largest and finest of the species, _Lycopodium clavatum_, with its long scaly stems and upright spikes of lighter green,--altogether a graceful though flowerless plant, which the herd-boy learns to select from among its fellows, and to bind round his cap,--goes trailing on the drier spots for many feet over the soil; while at the edge of trickling runnel or marshy hollow, a smaller and less hardy species, _Lycopodium inundatum_, takes its place. The marshes themselves bristle thick with the deep green horse tail, _Equisetum fluviatile_, with its fluted stem and verticillate series of linear brandies. Two other species of the same genus, _Equisetum sylvaticum_ and _Equisetum arvense_, flourish on the drier parts of the moor, blent with two species of minute ferns, the moonwort and the adder's tongue,--ferns that, like the magnificent royal fern (_Osmunda regalis_), though on a much humbler scale, bear their seed cases on independent stems, and were much sought after of old for imaginary virtues, which the modern schools of medicine refuse to recognize. Higher up the moor, ferns of ampler size occur, and what seems to be rushes, which bear atop conglobate panicles on their smooth leafless stems; but at its lower edge little else appears than the higher Acrogens,--ferns and their allies. There occurs, however, just beyond the first group of club mosses,--a remarkable exception in a solitary pine,--the advance guard of one of the ancient forests of the country, which may be seen far in the background, clothing with its shaggy covering of deep green the lower hill-slopes. And as we found in the Thallogens of that littoral zone over which we have just passed, representatives of the marine flora of the Silurian System, from the first appearance of organisms in its nether beds, to its bone-bed of the Upper Ludlow rocks, in which the Lycopodites first appear, so in the Acrogens of that moor, with its solitary coniferous tree, we may recognize an equally striking representative of the terrestrial flora which existed during the deposition of these Ludlow rocks, and of the various formations of the Old Red Sandstone, Lower, Middle, and Upper. [Illustration: Fig. 10. PINUS SYLVESTRIS. (Scotch Fir.)] [Illustration: Fig. 11. CALAMITE? Of the Lower Old Red Sandstone. Shetland. (One eighth nat. size.)] [Illustration: Fig. 12. LYCOPODITE? Of the Lower Old Red Sandstone. Thurso. (Mag. two diameters.)] In the upper beds of the Upper Silurian, as has been already remarked, Lycopodites are the only terrestrial plants yet found. In the Lower Old Red Sandstone we find added to these, with Thallogens that bear at least the same _general_ character as in the system beneath, minute ferns, and a greatly larger plant, allied to the horse tails. The Old Red flora seems to have been prevailingly an acrogenic flora; and yet with almost its first beginnings,--contemporary with at least the earlier fossils of the system in Scotland, we find a true polycotyledonous tree, not lower in the scale than the araucarites of the Coal Measures,--which in structure it greatly resembles,--or than the pines or cedars of our own times (see Fig. 3). In the Middle Old Red Sandstone there occurs, with plants representative apparently of the ferns and their allies, a somewhat equivocal and doubtful organism, which may have been the panicle or compound fruit of some aquatic rush; while in the Upper Old Red, just ere the gorgeous flora of the Coal Measures began to be, there existed in considerable abundance a stately fern, the _Cyclopteris Hibernicus_ (see Fig. 2), of mayhap not smaller proportions than our monarch of the British ferns, _Osmunda regalis_, associated with a peculiar lepidodendron, and what seems to be a lepidostrobus,--possibly the fructiferous spike or cone of the latter, mingled with carbonaceous stems, which, in the simplicity of their texture, and their abundance, give evidence of a low but not scanty vegetation. Ere passing to the luxuriant carboniferous flora, I shall make but one other remark. The existing plants whence we derive our analogies in dealing with the vegetation of this early period, contribute but little, if at all, to the support of animal life. The ferns and their allies remain untouched by the grazing animals. Our native club mosses, though once used in medicine, are positively deleterious; the horse tails, though harmless, so abound in silex, which wraps them round with a cuticle of stone, that they are rarely cropped by cattle; while the thickets of fern which cover our hill-sides, and seem so temptingly rich and green in their season, scarce support the existence of a single creature, and remain untouched in stem and leaf, from their first appearance in spring, until they droop and wither under the frosts of early winter. Even the insects that infest the herbaria of the botanist almost never injure his ferns. Nor are our resin-producing conifers, though they nourish a few beetles, favorites with the herbivorous tribes in a much greater degree. Judging from all we yet know, the earliest terrestrial flora may have covered the dry land with its mantle of cheerful green, and served its general purposes, chemical and others, in the well-balanced economy of nature; but the herb-eating animals would have fared but ill even where it throve most luxuriantly; and it seems to harmonize with the fact of its non-edible character, that up to the present time we know not that a single herbivorous animal lived among its shades. From all that appears, it may be inferred that it had not to serve the purposes of the floras of the passing time, in which, according to the poet, "The world's bread depends on the shooting of a seed." [Illustration: Fig. 13. FERN? of Lower Old Red Sandstone. Orkney. (Nat. Size.)] The flora of the Coal Measures was the richest and most luxuriant, in at least individual productions, with which the fossil botanist has formed any acquaintance. Never before or since did our planet bear so rank a vegetation as that of which the numerous coal seams and inflammable shales of the carboniferous period form but a portion of the remains,--the portion spared, in the first instance, by dissipation and decay, and in the second by the denuding agencies. Almost all our coal,--the stored up fuel of a world,--forms but a comparatively small part of the produce of this wonderful flora. Amid much that was so strange and antique of type in its productions as to set the analogies of the botanist at fault, there occurred one solitary order, not a few of whose species closely resembled their cogeners of the present time. I refer, of course, to its ferns. And these seem to have formed no small proportion of the entire flora of the period. Francis estimates the recent dorsiferous ferns of Great Britain at thirty-five species, and the species of all the other genera at six more,--forty-one species in all; and as the flowering plants of the country do not fall short of fourteen hundred species, the ferns bear to them the rather small proportion of about one to thirty-five; whereas of the British Coal Measure flora, in which we do not yet reckon quite three hundred species of plants, about a hundred and twenty were ferns. Three sevenths of the entire carboniferous flora of Britain belonged to this familiar class; and for about fifty species more we can discover no nearer analogies than those which connect them with the fern allies. And if with the British Coal Measure we include those also of the Continent of America, we shall find the proportions in favor of the ferns still greater. The number of carboniferous plants hitherto described amounts, says M. Ad. Brogniart, to about five hundred, and of these two hundred and fifty,--one half of the whole,--were ferns. [Illustration: Fig. 14.] [Illustration: Fig. 15.] [Illustration: Fig. 16.] [Illustration: Fig. 17.] [Illustration: Fig. 18.] [Illustration: Fig. 19.] [Illustration: FERNS OF THE COAL MEASURES.[6]] [Illustration: Fig. 20. ALTINGIA EXCELSA. Norfolk Island Pine. (Young Specimen.)] Rising in the scale from the lower to the higher vegetable forms of the system,--from its ferns to its trees,--we find great conifers,--so great that they must have raised their heads more than a hundred feet over the soil; and such was their abundance in this neighborhood, that one can scarce examine a fragment of coal beside one's household fire that is not charged with their carbonized remains. Though marked by certain peculiarities of structure, they bore, as is shown by the fossil trunks of Granton and Craigleith, the familiar outlines of true coniferous trees; and would mayhap have differed no more in appearance from their successors of the same order that now live in our forests, than these differ from the conifers of New Zealand or of New South Wales. We have thus, in the numerous ferns and numerous coniferous trees of the Coal Measures, known objects by which to conceive of some of the more prominent features of the flora of which they composed so large a part. We have not inadequate conceptions of at once the giants of its forests and the green swathe of its plains and hill-sides,--of its mighty trees and its dwarf _underwood_,--of its cedars of Lebanon, so to speak, and its hyssop of the wall. But of an intermediate class we have no existing representatives; and in this class the fossil botanist finds puzzles and enigmas with which hitherto at least he has been able to deal with only indifferent success. There is a view, however, sufficiently simple, which may be found somewhat to lessen, if not altogether remove, the difficulty. Nature does not dwell willingly in mediocrity; and so in all ages she as certainly produced trees, or plants of tree-like proportions and bulk, as she did minute shrubs and herbs. In not a few of the existing orders and families, such as the Rosaceæ, the Leguminosæ, the Myrtaceæ, and many others, we have plants of all sizes, from the creeping herb, half hidden in the sward, to the stately tree. The wild dwarf strawberry and minute stone-bramble are of the same order as our finer orchard trees,--apple, pear, and plum,--or as those noble hawthorn, mountain ash, and wild cherry trees, that impart such beauty to our lawns and woods; and the minute spring vetch and everlasting pea are denizens of the same great family as the tall locust and rosewood trees, and the gorgeous laburnum. Did there exist no other plants than the Rosaceæ or the Leguminosæ, we would possess, notwithstanding, herbs, shrubs, and trees, just as we do now. And in plants of a greatly humbler order we have instances of similar variety in point of size. The humblest grass in our meadows belongs to the same natural order as the tall bamboo, that, shooting up its panicles amid the jungles of India to the height of sixty feet, looks down upon all the second class trees of the country. Again, the minute forked spleenwort of Arthur Seat, which rarely exceeds three inches in length, is of the same family as those tree-ferns of New Zealand and Tasmania that rise to an elevation of from twenty to thirty feet. And we know how in the ferns provision is made for the attainment and maintenance of the tree-like size and character. The rachis, which in the smaller species is either subterranean or runs along the ground, takes in the tree-fern a different direction, and, rising erect, climbs slowly upwards in the character of a trunk or stem, and sends out atop, year after year, a higher and yet higher coronal of fronds. And in order to impart the necessary strength to this trunk, and to enable it to war for ages with the elements, its mass of soft cellular tissue is strengthened all round by internal buttresses of dense vascular fibre, tough and elastic as the strongest woods. Now, not a few of the more anomalous forms of the Coal Measures seem to be simply fern allies of the types Lycopodiaceæ, Marsileaceæ, and Equisetum, that, escaping from the mediocrity of mere herbs, shot up into trees,--some of them very great trees,--and that had of necessity to be furnished with a tissue widely different from that of their minuter contemporaries and successors. It was of course an absolute mechanical necessity, that if they were to present, by being tall and large, a wide front to the tempest, they should also be comparatively solid and strong to resist it; but with this simple mechanical requirement there seems to have mingled a principle of a more occult character. The Gymnogens or conifers were the highest vegetable existences of the period,--its true trees; and all the tree-like fern allies were strengthened to meet the necessities of their increased size, on, if I may so speak, a _coniferous_ principle. Tissue resembling that of their contemporary conifers imparted the necessary rigidity to their framework; nay, so strangely were they pervaded throughout by the coniferous characteristics, that it seems difficult to determine whether they really most resembled the acrogenous or gymnogenous families. The Lepidodendra,--great plants of the club moss type, that rose from fifty to seventy feet in height,--had well nigh as many points of resemblance to the coniferæ as to the Lycopodites. The Calamites,--reed-like, jointed plants, that more nearly resemble the Equisetaceæ than aught else which now exists, but which attained, in the larger specimens, to the height of ordinary trees, also manifest very decidedly, in their internal structure, some of the characteristics of the conifers. It has been remarked by Lindley and Hutton of even Sphenophyllum,--a genus of plants with verticillate leaves, of which at least six species occur in our Coal Measures, and which Brogniart refers to one of the humblest families of the fern allies,--that it seems at least as nearly related to the Coniferæ as to its lowlier representatives, the Marsileaceæ. And it is this union of traits, pertaining to what are now widely separated orders, that imparts to not a few of the vegetables of the Coal Measures their singularly anomalous character. [Illustration: Fig. 21. EAST INDIA TREE-FERN.[7] (_Asophila perrotetiana._)] [Illustration: Fig. 22. SECTION OF STEM OF TREE-FERN.[8] (_Cyathea._)] [Illustration: Fig. 23.] [Illustration: Fig. 24.] [Illustration: Fig. 25.] [Illustration: LEPIDODENDRON STERNBERGII.[9]] [Illustration: Fig. 26. CALAMITES MOUGEOTII.] [Illustration: Fig. 27. SPHENOPHYLLUM DENTATUM.] [Illustration: Fig. 28. SIGILLARIA RENIFORMIS.] Let me attempt introducing you more intimately to one of those plants which present scarce any analogy with existing forms, and which must have imparted so strange a character and appearance to the flora of the Coal Measures. The Sigillaria formed a numerous genus of the Carboniferous period: no fewer than twenty-two different species have been enumerated in the British coal fields alone; and such was their individual abundance, that there are great seams of coal which seem to be almost entirely composed of their remains. At least the ancient soil on which these seams rest, and on which their materials appear to have been elaborated from the elements, is in many instances as thickly traversed by their underground stems as the soil occupied by our densest forests is traversed by the tangled roots of the trees by which it is covered; and we often find associated with them in these cases the remains of no other plant. The Sigillaria were remarkable for their beautifully sculptured stems, various in their pattern, according to their species. All were fluted vertically, somewhat like columns of the Grecian Doric; and each flute or channel had its line of sculpture running adown its centre. In one species (_S. flexuosa_) the sculpture consists of round knobs, surrounded by single rings, like the heads of the bolts of the ship carpenter; in another (_S. reniformis_) the knobs are double, and of an oval form, somewhat resembling pairs of kidneys,--a resemblance to which the species owes its name. In another species (_S. catenulata_) what seems a minute chain of distinctly formed elliptical links drops down the middle of each flute; in yet another (_S. oculata_) the carvings are of an oval form, and, bearing each a round impression in its centre, they somewhat resemble rows of staring goggle-eyes; while the carvings in yet another species (_S. pachyderma_) consist chiefly of crescent-shaped depressions. The roots, or rather underground stems, of this curious genus attracted notice, from their singularity, long ere their connection with the carved and fluted stems had been determined, and have been often described as the "stigmaria" of the fossil botanist. They, too, have their curious carvings, consisting of deeply marked stigmata, quincuncially arranged, with each a little ring at its bottom, and, in at least one rare species, surrounded by a sculptured star. Unlike true roots, they terminate abruptly; each rootlet which they send forth was jointed to the little ring or dimpled knob at the bottom of the stigmata; and the appearance of the whole, as it radiated from the central mass, whence the carved trunk proceeded, somewhat resembled that of an enormous coach-wheel divested of the rim. Unfortunately we cannot yet complete our description of this strange plant. A specimen, traced for about forty feet across a shale bed, was found to bifurcate atop into two great branches,--a characteristic in which, with several others, it differed from most of the tree-ferns,--a class of plants to which Adolphe Brogniart is inclined to deem it related; but no specimen has yet shown the nature of its foliage. I am, however, not a little disposed to believe with Brogniart that it may have borne as leaves some of the supposed ferns of the Coal Measures; nowhere, at least, have I found these lie so thickly, layer above layer, as around the stems of Sigillaria; and the fact that, even in our own times, plants widely differing from the tree-ferns,--such, for instance, as one of the Cycadeæ,--should bear leaves scarce distinguishable from fern fronds, may well reconcile us to an apparent anomaly in the case of an ancient plant such as Sigillaria, whose entire constitution, so far as it has been ascertained, appears to have been anomalous. The sculpturesque character of this richly fretted genus was shared by not a few of its contemporaries. The Ulodendra, with their rectilinear rows of circular scars, and their stems covered with leaf-like carvings, rivalled in effect the ornately relieved torus of a Corinthian column: Favularia, Knorria, Halonia, many of the Calamites, and all the Lepidodendra, exhibited the most delicate sculpturing. In walking among the ruins of this ancient flora, the Palæontologist almost feels as if he had got among the broken fragments of Italian palaces, erected long ages ago, when the architecture of Rome was most ornate, and every moulding was roughened with ornament; and in attempting to call up in fancy the old Carboniferous forests, he has to dwell on this peculiar feature as one of the most prominent, and to see, in the multitude of trunks darkened above by clouds of foliage, that rise upon him in the prospect, the slim columns of an elder Alhambra, roughened with arabesque tracery and exquisite filagree work.

(Portland Dirt-bed.)] In the Oolitic flora we find a few peculiar features introduced. The Cyeadeæ,--a family of plants allied to the ferns on the one hand, and to the conifers on the other, and which in their general aspect not a little resemble stunted palms,--appear in this flora for the first time. Its coniferous genera, too, receive great accessions to their numbers, and begin to resemble, more closely than at an earlier period, the genera which still continue to exist. The cypresses, the yews, the thujas, the dammaras, all make their earliest appearance in the flora of the Oolite. Among our existing woods there seem to be but two conifers (that attain to the dignity of trees) indigenous to Britain,--the common yew, _Taxus baccata_, and the common Scotch fir, _Pinus sylvestris_; and yet we know that the latter alone formed, during the last few centuries, great woods, that darkened for many miles together the now barren moors and bare hill-sides of the Highlands of Scotland,--moors and hill-sides that, though long since divested of their last tree, are still known by their old name of _forests_. In the times of the Oolite, on the other hand, Britain had from fourteen to twenty different species of conifers; and its great forests, of whose existence we have direct evidence in the very abundant lignites of the system, must have possessed a richness and variety which our ancient fir woods of the historic or human period could not have possessed. With the Conifers and the Cycadeæ there were many ferns associated,--so many, that they still composed nearly two fifths of the entire flora; and associated with these, though in reduced proportions, we find the fern allies. The reduction, however, of these last is rather in species than in individuals. The Brora Coal, one of the most considerable Oolitic seams in Europe, seems to have been formed almost exclusively of an equisetum,--_E. columnare_. In this flora the more equivocal productions of the Coal Measures are represented by what seems to be the last of the Calamites; but it contains no Lepidodendra,--no Ulodendra,--no Sigillaria,--no Favularia,--no Knorria or Halonia. Those monsters of the vegetable world that united to the forms of its humbler productions the bulk of trees, had, with the solitary exception of the Calamites, passed into extinction; and ere the close of the system they too had disappeared. The forms borne by most of the Oolitic plants were comparatively familiar forms. With the Acrogens and Gymnogens we find the first indication of the Liliaceæ, or lily-like plants,--of plants, too, allied to the Pandanaceæ or screw pines, the fruits of which are sometimes preserved in a wonderfully perfect state of keeping in the Inferior Oolite, together with Carpolithes,--palm-like fruits, very ornately sculptured,--and the remains of at least one other monocotyledon, that bears the somewhat general name of an Endogenite. With these there occur a few disputed leaves, which I must persist in regarding as dicotyledonous. But they formed, whatever their true character, a very inconspicuous feature in the Oolitic flora; and not until the overlying Cretaceous System is ushered in do we find leaves in any considerable quantity decidedly of this high family; nor until we enter into the earlier Tertiaries do we succeed in detecting a true dicotyledonous tree. On such an amount of observation is this order of succession determined,--though the evidence is, of course, mainly negative,--that when, some eight or ten years ago, Dr. John Wilson, the learned Free Church missionary to the Parsees of India, submitted to me specimens of fossil woods which he had picked up in the Egyptian Desert, in order that I might if possible determine their age, I told him, ere yet the optical lapidary had prepared them for examination, that if they exhibited the coniferous structure, they might belong to any geologic period from the times of the Lower Old Red Sandstone downwards; but that if they manifested in their tissue the dicotyledonous character, they could not be older than the times of the Tertiary. On submitting them in thin slices to the microscope, they were found to exhibit the peculiar dicotyledonous structure as strongly as the oak or chestnut. And Lieutenant Newbold's researches in the deposit in which they occur has since demonstrated, on stratigraphical evidence, that not only does it belong to the great Tertiary division, but also to one of the comparatively modern formations of the Tertiary. [Illustration: Fig. 38 EQUISETUM COLUMNARE. (Nat. size.)] [Illustration: Fig. 39. CARPOLITHES CONICA. (Reduced one third.)] [Illustration: Fig. 40. CARPOLITHES BUCKLANDII.[10] (Reduced one third.)] [Illustration: Fig. 41. ACER TRILOBATUM.[11] (Miocene of OEningen.)] [Illustration: Fig. 42. ULMUS BRONNII.[12] (Miocene of Bohemia.)] [Illustration: Fig. 43. PALMACITES LAMANONIS. (A Palm of the Miocene of Aix.)] The earlier flora of this Tertiary division presents an aspect widely different from that of any of the previous ones. The ferns and their allies sink into their existing proportions; nor do the coniferæ, previously so abundant, occupy any longer a prominent place. On the other hand, the dicotyledonous herbs and trees, previously so inconspicuous in creation, are largely developed. Trees of those Amentiferous orders to which the oak, the hazel, the beech, and the plane belong, were perhaps not less abundant in the Eocene woods than in those of the present time: they were mingled with trees of the Laurel, the Leguminous, and the Anonaceous or custard apple families, with many others; and deep forests, in the latitude of London (in which the intertropical forms must now be protected, as in the Crystal Palace, with coverings of glass, and warmed by artificial heat), abounded in graceful palms. Mr. Bowerbank found in the London clay of the island of Sheppey alone the fruits of no fewer than thirteen different species of this picturesque family, which lends so peculiar a feature to the landscapes in which it occurs; and ascertained that the undergrowth beneath was composed, in large proportion, of creeping plants of the gourd and melon order. From the middle or Miocene flora of the Tertiary division,--of which we seem to possess in Britain only the small but interesting fragment detected by his Grace the Duke of Argyll among the trap-beds of Mull,--most of the more exotic forms seem to have been excluded. The palms, however, still survive in no fewer than thirty-one different species, and we find in great abundance, in the place of the other exotics, remains of the plane and buckthorn families,--part of a group of plants that in their general aspect, as shown in the Tertiary deposits of the Continent, not a little resembled the vegetation of the United States at the present day. The nearer we approach to existing times, the more familiar in form and outline do the herbs and trees become. We detect, as has been shown, at least one existing _order_ in the ferns of the Coal Measures; we detect at least existing _genera_ among the Coniferæ, Equisetaceæ, and Cycadaceæ of the Oolite; the acacias, gourds, and laurels of the Eocene flora, and the planes, willows, and buckthorns of the Miocene, though we fail to identify their species with aught that now lives, still more strongly remind us of the recent productions of our forests or conservatories; and, on entering, in our downward course, the Pleistocene period, we at length find ourselves among familiar _species_. On old terrestrial surfaces, that date before the times of the glacial period, and underlie the boulder clay, the remains of forests of oak, birch, hazel, and fir have been detected,--all of the familiar species indigenous to the country, and which still flourish in our native woods. And it was held by the late Professor Edward Forbes, that the most ancient of his five existing British floras,--that which occurs in the south-west of Ireland, and corresponds with the flora of the northwest of Spain and the Pyrenees,--had been introduced into the country as early, perhaps, as the times of the Miocene. Be this, however, as it may, there can rest no doubt on the great antiquity of the prevailing trees of our indigenous forests. The oak, the birch, the hazel, the Scotch fir, all lived, I repeat, in what is now Britain, ere the last great depression of the land. The gigantic northern elephant and rhinoceros, extinct for untold ages, forced their way through their tangled branches; and the British tiger and hyæna harbored in their thickets. Cuvier framed an argument for the fixity of species on the fact that the birds and beasts embalmed in the catacombs were identical in every respect with the animals of the same kinds that live now. But what, it has been asked, was a brief period of three thousand years, compared with the geologic ages? or how could any such argument be founded on a basis so little extended? It is, however, to no such narrow basis we can refer in the case of these woods. All human history is comprised in the nearer corner of the immense period which they measure out; and yet, from their first appearance in creation till now they have not altered a single fibre. And such, on this point, is the invariable testimony of Palæontologic science,--testimony so invariable, that no great Palæontologist was ever yet an asserter of the development hypothesis. With the existing trees of our indigenous woods it is probable that in even these early times a considerable portion of the herbs of our recent flora would have been associated, though their remains, less fitted for preservation, have failed to leave distinct trace behind them. We at least know generally, that with each succeeding period there appeared a more extensively useful and various vegetation than that which had gone before. I have already referred to the sombre, unproductive character of the earliest terrestrial flora with which we are acquainted. It was a flora unfitted, apparently, for the support of either graminivorous bird or herbivorous quadruped. The singularly profuse vegetation of the Coal Measures was, with all its wild luxuriance, of a resembling cast. So far as appears, neither flock nor herd could have lived on its greenest and richest plains; nor does even the flora of the Oolite seem to have been in the least suited for the purposes of the shepherd or herdsman. Not until we enter on the Tertiary periods do we find floras amid which man might have profitably labored as a dresser of gardens, a tiller of fields, or a keeper of flocks and herds. Nay, there are whole orders and families of plants of the very first importance to man which do not appear until late in even the Tertiary ages. Some degree of doubt must always attach to merely negative evidence; but Agassiz, a geologist whose statements must be received with respect by every student of the science, finds reason to conclude that the order of the Rosaceæ,--an order more important to the gardener than almost any other, and to which the apple, the pear, the quince, the cherry, the plum, the peach, the apricot, the victorine, the almond, the raspberry, the strawberry, and the various brambleberries belong, together with all the roses and the potentillas,--was introduced only a short time previous to the appearance of man. And the true grasses,--a still more important order, which, as the corn-bearing plants of the agriculturist, feed at the present time at least two thirds of the human species, and in their humbler varieties form the staple food of the _grazing_ animals,--scarce appear in the fossil state at all. They are peculiarly plants of the human period. Let me instance one other family of which the fossil botanist has not yet succeeded in finding any trace in even the Tertiary deposits, and which appears to have been specially created for the gratification of human sense. Unlike the Rosaceæ, it exhibits no rich blow of color, or tempting show of luscious fruit;--- it does not appeal very directly to either the sense of taste or of sight: but it is richly odoriferous; and, though deemed somewhat out of place in the garden for the last century and more, it enters largely into the composition of some of our most fashionable perfumes. I refer to the _Labiate_ family,--a family to which the lavenders, the mints, the thymes, and the hyssops belong, with basil, rosemary, and marjoram,--all plants of "gray renown," as Shenstone happily remarks in his description of the herbal of his "Schoolmistress." "Herbs too she knew, and well of each could speak, That in her garden sipped the silvery dew, Where no vain flower disclosed a gaudy streak, But herbs for use and physic not a few, Of gray renown within those borders grew. The tufted basil, pun-provoking thyme, And fragrant balm, and sage of sober hue. "And marjoram sweet in shepherd's posie found, And lavender, whose spikes of azure bloom Shall be erewhile in arid bundles bound, To lurk amid her labors of the loom, And crown her kerchiefs clean with meikle rare perfume. "And here trim rosemary, that whilom crowned The daintiest garden of the proudest peer, Ere, driven from its envied site, it found A sacred shelter for its branches here, Where, edged with gold, its glittering skirts appear, With horehound gray, and mint of softer green." All the plants here enumerated belong to the labiate family; which, though unfashionable even in Shenstone's days, have still their products favorably received in the very best society. The rosemary, whose banishment from the gardens of the great he specially records, enters largely in the composition of eau de Cologne. Of the lavenders, one species (_Lavendula vera_) yields the well known lavender oil, and another (_L. latifolio_) the spike oil. The peppermint (_Meantha viridus_) furnishes the essence so popular under that name among our confectioners; and one of the most valued perfumes of the East (next to the famous _Attar_, a product of the Rosaceæ) is the oil of the _Patchouly_ plant, another of the labiates. Let me indulge, ere quitting this part of the subject, in a single remark. There have been classes of religionists, not wholly absent from our own country, and well known on the Continent, who have deemed it a merit to deny themselves every pleasure of sense, however innocent and delicate. The excellent but mistaken Pascal refused to look upon a lovely landscape; and the Port Royalist nuns remarked, somewhat simply for their side of the argument, that they seemed as if warring with Providence, seeing that the favors which he was abundantly showering upon them, they, in obedience to the stern law of their lives, were continually rejecting. But it is better, surely, to be on the side of Providence against Pascal and the nuns, than on the side of Pascal and the nuns against Providence. The great Creator, who has provided so wisely and abundantly for all his creatures, knows what is best for us, infinitely better than we do ourselves; and there is neither sense nor merit, surely, in churlishly refusing to partake of that ample entertainment, sprinkled with delicate perfumes, garnished with roses, and crowned with the most delicious fruit, which we now know was not only specially prepared for us, but also got ready, as nearly as we can judge, for the appointed hour of our appearance at the feast. This we also know, that when the Divine Man came into the world,--unlike the Port Royalists, he did not refuse the temperate use of any of these luxuries, not even of that "ointment of spikenard, very precious" (a product of the labiate family), with which Mary anointed his feet. [Illustration: Fig. 44. CYCLOPHTHALMUS BUCKLANDI. (A Fossil Scorpion of the Coal Measures of Bohemia.)] [Illustration: Fig. 45. FOSSIL DRAGON-FLY. Solenhofen.] Though it may at first seem a little out of place, let us anticipate here, for the sake of the illustration which it affords, one of the sections of the other great division of our subject,--that which treats of the fossil animals. Let us run briefly over the geologic history of insects, in order that we may mark the peculiar light which it casts on the character of the ancient floras. No insects have yet been detected in the Silurian or Old Red Sandstone Systems. They first appear amid the hard, dry, flowerless vegetation of the Coal Measures, and in genera suited to its character. Among these the scorpions take a prominent place,--carnivorous arachnidæ of ill repute, that live under stones and fallen trunks, and seize fast with their nippers upon the creatures on which they prey, crustaceans usually, such as the wood-louse, or insects, such as the earth-beetles and their grubs. With the scorpions there occur cockroaches of types not at all unlike the existing ones, and that, judging from their appearance, must have been foul feeders, to which scarce anything could have come amiss as food. Books, manuscripts, leather, ink, oil, meat, even the bodies of the dead, are devoured indiscriminately by the recent _Blatta gigantea_ of the warmer parts of the globe,--one of the most disagreeable pests of the European settler, or of war vessels on foreign stations. I have among my books an age-embrowned copy of Ramsay's "Tea Table Miscellany," that had been carried into foreign parts by a musical relation, after it had seen hard service at home, and had become smoke dried and black; and yet even it, though but little tempting, as might be thought, was not safe from the cockroaches; for, finding it left open one day, they ate out in half an hour half its table of contents, consisting of several leaves. Assuredly, if the ancient _Blattæ_ were as little nice in their eating as the devourers of the "Tea Table Miscellany," they would not have lacked food amid even the unproductive flora and meagre fauna of the Coal Measures. With these ancient cockroaches a few locusts and beetles have been found associated, together with a small _Tinea_,--a creature allied to the common clothes-moth, and a _Phasmia_,--a creature related to the spectre insects. But the group is an inconsiderable one; for insects seem to have occupied no very conspicuous place in the carboniferous fauna. The beetles appear to have been of the wood and seed devouring kinds, and would probably have found their food among the conifers; the _Phasmidæ_ and grasshoppers would have lived on the tender shoots of the less rigid plants their contemporaries; the _Tinea_, probably on ligneous or cottony fibre. Not a single insect has the system yet produced of the now numerous kinds that seek their food among flowers. In the Oolitic ages, however, insects become greatly more numerous,--so numerous that they seemed to have formed almost exclusively the food of the earliest mammals, and apparently also of some of the flying reptiles of the time. The magnificent dragon-flies, the carnivorous tyrants of their race, were abundant; and we now know, that while they were, as their name indicates, dragons to the weaker insects, they themselves were devoured by dragons as truly such as were ever yet feigned by romancer of the middle ages. Ants were also common, with crickets, grasshoppers, bugs both of the land and water, beetles, two-winged flies, and, in species distinct from the preceding carboniferous ones, the disgusting cockroaches. And for the first time amid the remains of a flora that seems to have had its few flowers,--though flowers could have formed no conspicuous feature in even an Oolitic landscape,--we detect in a few broken fragments of the wings of butterflies, decided trace of the flower-sucking insects. Not, however, until we enter into the great Tertiary division do these become numerous. The first bee makes its appearance in the amber of the Eocene, locked up hermetically in its gem-like tomb,--an embalmed corpse in a crystal coffin,--along with fragments of flower-bearing herbs and trees. The first of the Bombycidæ too,--insects that maybe seen suspended over flowers by the scarce visible vibrations of their wings, sucking the honied juices by means of their long, slender trunks,--also appear in the amber, associated with moths, butterflies, and a few caterpillars. Bees and butterflies are present in increased proportions in the latter Tertiary deposits: but not until that terminal creation to which we ourselves belong was ushered on the scene did they receive their fullest development. There is exquisite poetry in Wordsworth's reference to "the soft murmur of the vagrant bee,"-- "A slender sound, yet hoary Time Doth to the soul exalt it with the chime Of all his years; a company Of ages coming, ages gone, Nations from before them sweeping." And yet, mayhap, the naked scientific facts of the history of this busy insect are scarcely less poetic than the pleasing imagination of the poet regarding it. They tell that man's world, with all its griefs and troubles, is more emphatically a world of flowers than any of the creations that preceded it, and that as one great family--the grasses--were called into existence, in order, apparently, that he might enter in favoring circumstances upon his two earliest avocations, and be in good hope a keeper of herds and a tiller of the ground; and as another family of plants--the Rosaceæ--was created in order that the gardens which it would be also one of his vocations to keep and to dress should have their trees "good for food and pleasant to the taste;" so flowers in general were profusely produced just ere he appeared, to minister to that sense of beauty which distinguishes him from all the lower creatures, and to which he owes not a few of his most exquisite enjoyments. The poet accepted the bee as a sign of high significance: the geologist also accepts her as a sign. Her entombed remains testify to the gradual fitting up of our earth as a place of habitation for a creature destined to seek delight for the mind and the eye as certainly as for the grosser senses, and in especial marks the introduction of the stately forest trees, and the arrival of the delicious flowers. And, "Thus in their stations lifting toward the sky The foliaged head in cloud-like majesty, The shadow-casting race of trees survive: Thus in the train of spring arrive Sweet flowers: what living eye hath viewed Their myriads? endlessly renewed Wherever strikes the sun's glad ray, Where'er the subtile waters stray, Wherever sportive zephyrs bend Their course, or genial showers descend." LECTURE SECOND. THE PALÆONTOLOGICAL HISTORY OF ANIMALS. Amid the unceasing change and endless variety of nature there occur certain great radical ideas, that, while they form, if I may so express myself, the groundwork of the change,--the basis of the variety,--admit in themselves of no change or variety whatever. They constitute the aye-enduring tissue on which the ever-changing patterns of creation are inscribed: the patterns are ever varying; the tissue which exhibits them for ever remains the same. In the animal kingdom, for instance, the prominent ideas have always been uniform. However much the faunas of the various geologic periods may have differed from each other, or from the fauna which now exists, in their general aspect and character, they were all, if I may so speak, equally underlaid by the great leading ideas which still constitute the master types of animal life. And these leading ideas are four in number. _First_, there is the _star-like_ type of life,--life embodied in a form that, as in the corals, the sea-anemones, the sea-urchins, and the star-fishes, radiates outwards from a centre; _second_, there is the _articulated_ type of life,--life embodied in a form composed, as in the worms, crustaceans, and insects, of a series of rings united by their edges, but more or less moveable on each other; _third_, there is the bilateral or _molluscan_ type of life,--life embodied in a form in which there is a duality of corresponding parts, ranged, as in the cuttle-fishes, the clams, and the snails, on the sides of a central axis or plane; and _fourth_, there is the _vertebrate_ type of life,--life embodied in a form in which an internal skeleton is built up into two cavities placed the one over the other; the upper for the reception of the nervous centres, cerebral and spinal,--the lower for the lodgment of the respiratory, circulatory, and digestive organs. Such have been the four central ideas of the faunas of every succeeding creation, except perhaps the earliest of all, that of the Lower Silurian System, in which, so far as is yet known, only three of the number existed,--the radiated, articulated, and molluscan ideas or types. That Omnipotent Creator, infinite in his resources,--who, in at least the details of his workings, seems never yet to have repeated himself, but, as Lyell well expresses it, breaks, when the parents of a species have been moulded, the dye in which they were cast,--manifests himself, in these four great ideas, as the unchanging and unchangeable One. They serve to bind together the present with all the past; and determine the unity of the authorship of a wonderfully complicated design, executed on a groundwork broad as time, and whose scope and bearing are deep as eternity. The fauna of the Silurian System bears in all its three great types the stamp of a fashion peculiarly antique, and which, save in a few of the mollusca, has long since become obsolete. Its radiate animals are chiefly corals, simple or compound, whose inhabitants may have somewhat resembled the sea-anemones; with zoophites, akin mayhap to the sea-pens, though the relationship must have been a remote one; and numerous crinoids, or stone lilies, some of which consisted of but a sculptured calyx without petals, while others threw off a series of long, flexible arms, that divided and subdivided like the branches of a tree, and were thickly fringed by hair-like fibres. There is great variety and beauty among these Silurian crinoids; and, from the ornate sculpture of their groined and ribbed _capitals_ and slender _columns_, the Gothic architect might borrow not a few striking ideas. [Illustration: Fig. 46. CYATHAXONIA DALMANI.] The difference between the older and newer fashions, as exemplified in the cup-shaped corals, may be indicated in a single sentence. The ancient corals were stars of four rays, or of multiples of four; the modern corals are stars of six rays, or of multiples of six. But though, at a certain definite period,--that during which the great Palæozoic division ended and the Secondary division began--nature, in forming this class of creatures, discarded the number four, and adopted instead the number six, the great leading idea of the star itself was equally retained in corals of the modern as in those of the more ancient type. [Illustration: Fig. 47. GLYPTOCRINUS DECADACTYLUS. (Hudson River Group, Lower Silurian.)] [Illustration: Fig. 48. CALYMENE BLUMENBACHII.] [Illustration: Fig. 49. ORTHISINA VERNEUILI.] [Illustration: Fig. 50. LITUITES CORNU-ARIETIS.] [Illustration: Fig. 51. LINGULA LOWISII.] The articulata of the Silurian period bore a still more peculiar character. They consisted mainly of the Trilobites,--a family in whose nicely-jointed shells the armorer of the middle ages might have found almost all the contrivances of his craft, anticipated, with not a few besides which he had failed to discover; and which, after receiving so immense a development during the middle and later times of the Silurian period, that whole rocks were formed almost exclusively of their remains, gradually died out in the times of the Old Red Sandstone, and disappeared for ever from creation after the Carboniferous Limestone had been deposited. The Palæontologist knows no more unique family than that of the Trilobites, or a family more unlike any which now exists, or a family which marks with more certainty the early rocks in which they occur. And yet, though formed in a fashion that perished myriads of ages ago, how admirably does it not exhibit the articulated type of being, and illustrate that unity of design which, amid endless diversity, pervades all nature. The mollusca of the Silurians ranged from the high cephalopoda, represented in our existing seas by the nautili and the cuttle-fishes, to the low brachipods, some of whose congeners may still be detected in the terebratula of our Highland lochs and bays, and some in the lingulæ of the southern hemisphere. The cephalopods of the system are all of an obsolete type, that disappeared myriads of ages ago,--a remark which, with the exceptions just intimated, and perhaps one or two others, applies equally to its brachipods; but of at least two of its intermediate families,--the gasteropoda and lamellibranchiata,--several of the forms resemble those of recent shells of the temperate latitudes. In its general aspect, however, the Silurian fauna, antiquely fashioned, as I have said, as became its place in the primeval ages of existence, was unlike any other which the world ever saw; and the absence of the vertebrata, or at least the inconspicuous place which they occupied if they were at all present, must have imparted to the whole, as a group, a humble and mediocre character. It seems to have been for many ages together a creation of molluscs, corals, and Crustacea. At length, in an upper bed of the system, immediately under the base of the Old Red Sandstone, the remains of the earliest known fishes appear, blent with what also appears for the first time,--the fragmentary remains of a terrestrial vegetation. The rocks beneath this ancient bone-bed have yielded, as I have already said, no trace of any plant higher than the Thallogens, or at least not higher than the Zosteracea,--plants whose proper habitat is the sea; but, through an apparently simultaneous advance of the two kingdoms, animal and vegetable,--though of course the simultaneousness may be but merely apparent,--the first land plants and the first vertebrates appear together in the same deposit. What, let us inquire, is the character of these ancient fishes, that first complete the scale of animated nature in its four master ideas, by adding the vertebrate to the invertebrate divisions? So far as is yet known, they all consist of one well marked order,--that placoidal order of Agassiz that to an internal framework of cartilage adds an external armature, consisting of plates, spines, and shagreen points of solid bone. Either of the two kinds of dog-fishes on our coasts,--the spiked or spotted,--maybe accepted as not inadequate representatives of this order as it now exists. The Port Jackson shark, however,--a creature that to the dorsal spines and shagreen-covered skin of the common dog-fish adds a mouth terminal at the snout, not placed beneath, as in most other sharks, and a palate covered with a dense pavement of crushing teeth,--better illustrates the order as it first appeared in creation than any of our British placoids.

(_Eocene._)] And here let me adduce another and very remarkable instance of the correspondence which obtains between the sequence in which certain classes of organisms were first ushered into being, and the order of classification adopted, after many revisions, by the higher naturalists. Cuvier, with not a few of the ichthyologists who preceded him, arranged the fishes into two distinct series,--the Cartilaginous and Osseous; and these last he mainly divided into the hard or spiny-finned fishes, and the soft or joint-finned fishes. He placed the sturgeon in his Cartilaginous series; while in his soft-finned order he found a place for the Polypterus of the Nile and the Lepidosteus of the Ohio and St. Lawrence. But the arrangement, though it seemed at the time one of the best and most natural possible, failed to meet any corresponding arrangement in the course of geologic history. The place assigned to the class of fishes as a whole corresponded to their place in the Palæontological scale;--- first of the vertebrate division in the order of their appearance, they border, as in the "_Animal Kingdom_" of the naturalist, on the invertebrate divisions. But it was not until the new classification of Agassiz had ranged them after a different fashion that the correspondence became complete in all its parts. First, he erected the fishes that to an internal cartilaginous skeleton unite an external armature of plates and points of bone, into his Placoid order; next, gathering together a mere handful of individuals from among the various orders and families over which they had been scattered,--the sturgeons from among the cartilaginous fishes, and the lepidosteus and polypterus from among the Clupia or herrings,--he erected into a small ganoid order all the fishes that are covered, whatever the consistency of their skeleton, by a continuous or nearly continuous armor of enamelled bone, or by great bony plates that lock into each other at their edges. Out of the remaining fishes,--those covered with scales of a horny substance, and which now comprise nearly nine tenths of the whole class,--he erected two orders more,--a Ctenoid order, consisting of fishes whose scales, like those of the perch, are pectinated at their lower edges like the teeth of a comb, and a Cycloid order, composed of fishes whose scales, like those of the salmon, are defined all around by a simple continuous margin; and no sooner was the division effected than it was found to cast a singularly clear light on the early history of the class. The earliest fishes--firstborn of their family--seem to have been all placoids. The Silurian System has not yet afforded trace of any other vertebral animal. With the Old Red Sandstone the ganoids were ushered upon the scene in amazing abundance; and for untold ages, comprising mayhap millions of years, the entire ichthyic class consisted, so far as is yet known, of but these two orders. During the times of the Old Red Sandstone, of the Carboniferous, of the Permian, of the Triassic, and of the Oolitic Systems, all fishes, though apparently as numerous individually as they are now, were comprised in the ganoidal and placoidal orders. The period of these orders seems to have been nearly correspondent with the reign, in the vegetable kingdom, of the Acrogens and Gymnogens, with the intermediate classes, their allies. At length, during the ages of the Chalk, the Cycloids and Ctenoids were ushered in, and were gradually developed in creation until the human period, in which they seem to have reached their culminating point, and now many times exceed in number and importance all other fishes. We do not see a sturgeon (our British representative of the ganoids) once in a twelvemonth; and though the skate and dog-fish (our representatives of the placoids) are greatly less rare, their number bears but a small proportion to that of the fishes belonging to the two prevailing orders, of which thousands of boat-loads are landed on our coasts every day. The all but entire disappearance of the ganoids from creation is surely a curious and not unsuggestive circumstance. In the human family there are races that have long since reached their culminating point, and are now either fast disappearing or have already disappeared. The Aztecs of Central America, or the Copts of the valley of the Nile, are but the inconsiderable fragments of once mighty nations, memorials of whose greatness live in the vast sepulchral mounds of the far West, or in the temples of Thebes or Luxor, or the pyramids of Gizah. But in the rivers of these very countries,--in the Polypterus of the Nile, or the Lepidosteus of the Mississippi,--we are presented with the few surviving fragments of a dynasty compared with which that of Egypt or of Central America occupied but an exceedingly small portion of either space or time. The dynasty of the ganoids was at one time coextensive with every river, lake, and sea, and endured during the unreckoned _eons_ which extended from the times of the Lower Old Red Sandstone until those of the Chalk. I may here mention, that as there are orders of plants, such as the Rosaceæ and the Grasses, that scarce preceded man in their appearance, so there are families of fishes that seem peculiarly to belong to the human period. Of these, there is a family very familiar on our coasts, and which, though it furnishes none of our higher ichthyic luxuries, is remarkable for the numbers of the human family which it provides with a wholesome and palatable food. The delicate Salmonidæ and the Pleuronectidæ,--families to which the salmon and turbot belong,--were ushered into being as early as the times of the Chalk; but the Gadidæ or cod family,--that family to which the cod proper, the haddock, the dorse, the whiting, the coal-fish, the pollock, the hake, the torsk, and the ling belong, with many other useful and wholesome species,--did not precede man by at least any period of time appreciable to the geologist. No trace of the family has yet been detected in even the Tertiary rocks. [Illustration: Fig. 57 PTERICHTHYS OBLONGUS. (One half nat. size.)] Of the ganoids of the second age of vertebrate existence,--that of the Old Red Sandstone,--some were remarkable for the strangeness of their forms, and some for constituting links of connection which no longer exist in nature, between the ganoid and placoid orders. The Acanth family, which ceased with the Coal Measures, was characterized, especially in its Old Red species, by a combination of traits common to both orders; and among the extremer forms, in which Palæontologists for a time failed to detect that of the fish at all, we reckon those of the genera Coccosteus, Pterichthys, and Cephalaspis. The more aberrant genera, however, even while they consisted each of several species, were comparatively short lived. The Coccosteus and Cephalaspis were restricted to but one formation apiece; while the Pterichthys, which appears for the first time in the lower deposits of the Old Red Sandstone, becomes extinct at its close. On the other hand, some of the genera that exemplified the general type of their class were extremely long lived. The Celacanths were reproduced in many various species, from the times of the Lower Old Red Sandstone to those of the Chalk; and the Cestracions, which appear in the Upper Ludlow Rocks as the oldest of fishes, continue in at least one species to exist still. It would almost seem as if some such law influenced the destiny of genera in this ichthyic class, as that which we find so often exemplified in our species. The dwarf, or giant, or deformed person, is seldom a long liver;--all the more remarkable instances of longevity have been furnished by individuals cast in the ordinary mould and proportions of the species. Not a few of these primordial ganoids wore, however, of the highest rank and standing ever exemplified by their class; and we find Agassiz boldly assigning a reason for their superiority to their successors, important for the fact which it embodies, and worthy, as coming from him, of our most respectful attention. "It is plain," we find him saying, "that before the class of reptiles was introduced upon our globe, the fishes, being then the only representatives of the type of vertebrata, were invested with the characters of a higher order, embodying, as it were, a prospective view of a higher development in another class, which was introduced as a distinct type only at a later period; and from that time the reptilian character, which had been so prominent in the oldest fishes, was gradually reduced, till in more recent periods, and in the present creation, the fishes lost all this herpetological relationship, and were at last endowed with characters which contrast as much, when compared with those of reptiles, as they agreed closely in the beginning. Lepidosteus alone reminds us in our time of these old-fashioned characters of the class of fishes as it was in former days." [Illustration: Fig. 58 PLEURACANTHUS LÆVISSIMUS. (_Coal Measures._) (Half nat. size.)] The ancient fishes seem to have received their fullest development during the Carboniferous period. Their number was very great: some of them attained to an enormous size, and, though the true reptile had already appeared, they continued to retain, till the close of the system, the high reptilian character and organization. Nothing, however, so impresses the observer as the formidable character of the offensive weapons with which they were furnished, and the amazing strength of their defensive armature. I need scarce say, that the Palæontologist finds no trace in nature of that golden age of the world, of which the poets delighted to sing, when all creatures lived together in unbroken peace, and war and bloodshed were unknown. Ever since animal life began upon our planet, there existed, in all the departments of being, carnivorous classes, who could not live but by the death of their neighbors, and who were armed, in consequence, for their destruction, like the butcher with his axe and knife, and the angler with his hook and spear. But there were certain periods in the history of the past, during which these weapons assumed a more formidable aspect than at others; and never were they more formidable than in the times of the Coal Measures. The teeth of the Rhizodus--a ganoidal fish of our coal fields--were more sharp and trenchant than those of the crocodile of the Nile, and in the larger specimens fully four times the bulk and size of the teeth of the hugest reptile of this species that now lives. The dorsal spine of its contemporary, the Gyracanthus, a great placoid, much exceeded in size that of any existing fish: it was a mighty spear head, ornately carved like that of a New Zealand chief, but in a style that, when he first saw a specimen in my collection, greatly excited the admiration of Mr. Ruskin. But one of the most remarkable weapons of the period was the sting of the Pleuracanthus, another great placoid of the age of gigantic fishes. It was sharp and polished as a stiletto, but, from its rounded form and dense structure, of great strength; and along two of its sides, from the taper point to within a few inches of the base, there ran a thickly-set row of barbs, hooked downwards, like the thorns that bristle on the young shoots of the wild rose, and which must have rendered it a weapon not merely of destruction, but also of torture. The defensive armor of the period, especially that of its ganoids, seems to have been us remarkable for its powers of resistance as the offensive must have been for their potency in the assault; and it seems probable that in the great strength of the bony and enamelled armature of this order of fishes we have the secret of the extremely formidable character of the teeth, spines, and stings that coexisted along with it. [Illustration: Fig. 59. CARCHARIAS PRODUCTUS. Cutting Tooth. (_Miocene._)] [Illustration: Fig. 60. PLACODUS GIGAS. Crushing Teeth. (_Trias._)] Such of the fishes of the present time as live on crustacea and the shelled molluscs,--such as the Wrasse or rock-fish family, and at least one of the Goby family, the sea-wolf,--have an apparatus of crushing teeth greatly more solid and strong than the teeth of such of their contemporaries as are either herbivorous or feed on the weaker families of their own class. A similar remark applies to the ancient sharks, as contrasted with those of later times. So long as the strongly-armed ganoidal order prevailed in nature, the sharks were furnished with massive crushing teeth; but when the ganoids waned in creation, and the soft-scaled cycloid and ctenoid orders took and amply filled the place which they had left vacant, the well known modern form of sharks' teeth was introduced,--a form much rather suited for cutting soft bodies than for crushing hard ones. In fine, the offensive weapons of the times of the Coal Measures seem very formidable, just as those personal weapons of the middle ages seem so that were borne at a time when every soldier took the field cased in armor of proof. The slim scimitar or slender rapier would have availed but little against massive iron helmets or mail coats of tempered steel. And so the warriors of the period armed themselves with ponderous maces, battle-axes as massive as hammers, and double-handed swords of great weight and strength. Before passing onwards to other and higher classes and orders, as they occurred in creation, permit me to make the formidable armor of the earlier fishes, offensive and defensive, the subject of a single remark. We are told by Goethe, in his autobiography, that he had attained his sixth year when the terrible earthquake at Lisbon took place,--"an event," he says, "which greatly disturbed" his "peace of mind for the first time." He could not reconcile a catastrophe so suddenly destructive to thousands, with the ideas which he had already formed for himself of a Providence all-powerful and all-benevolent. But he afterwards learned, he tells us, to recognize in such events the "_God of the Old Testament._" I know not in what spirit the remark was made; but this I know, that it is the God of the Old Testament whom we see exhibited in all nature and all providence; and that it is at once wisdom and duty in his rational creatures, however darkly they may perceive or imperfectly they may comprehend, to hold in implicit faith that the Adorable Monarch of all the past and of all the future is a King who "can do no wrong." This early exhibition of tooth, and spine, and sting,--of weapons constructed alike to cut and to pierce,--to unite two of the most indispensable requirements of the modern armorer,--a keen edge to a strong back,--nay, stranger still, the examples furnished in this primeval time, of weapons formed not only to kill, but also to torture,--must be altogether at variance with the preconceived opinions of those who hold that until man appeared in creation, and darkened its sympathetic face with the stain of moral guilt, the reign of violence and outrage did not begin, and that there was no death among the inferior creatures, and no suffering. But preconceived opinion, whether it hold fast, with Lactantius and the old Schoolmen, to the belief that there can be no antipodes, or assert, with Caccini and Bellarmine, that our globe hangs lazily in the midst of the heavens, while the sun moves round it, must yield ultimately to scientific truth. And it is a truth as certain as the existence of a southern hemisphere, or the motion of the earth round both its own axis and the great solar centre, that, untold ages ere man had sinned or suffered, the animal creation exhibited exactly its present state of war,--that the strong, armed with formidable weapons, exquisitely constructed to kill, preyed upon the weak; and that the weak, sheathed, many of them, in defensive armor equally admirable in its mechanism, and ever increasing and multiplying upon the earth far beyond the requirements of the mere maintenance of their races, were enabled to escape, as species, the assaults of the tyrant tribes, and to exist unthinned for unreckoned ages. It has been weakly and impiously urged,--as if it were merely with the geologist that men had to settle this matter,--that such an economy of warfare and suffering,--of warring and of being warred upon,--would be, in the words of the infant Goethe, unworthy of an all-powerful and all-benevolent Providence, and in effect a libel on his government and character. But that grave charge we leave the objectors to settle with the great Creator himself. Be it theirs, not ours, according to the poet, to "Snatch from his hand the balance and the rod, Rejudge his justice, be the god of God." Be it enough for the geologist rightly to interpret the record of creation,--to declare the truth as he finds it,--to demonstrate, from evidence no clear intellect ever yet resisted, that he, the Creator, from whom even the young lions seek their food, and who giveth to all the beasts, great and small, their meat in due season, ever wrought as he now works in his animal kingdom,--that he gave to the primeval fishes their spines and their stings,--to the primeval reptiles their trenchant teeth and their strong armor of bone,--to the primeval mammals their great tusks and their sharp claws,--that he of old divided all his creatures, as now, into animals of prey and the animals preyed upon,--that from the beginning of things he inseparably established among his non-responsible existences the twin laws of generation and of death,--nay, further, passing from the established truths of _Geologic_ to one of the best established truths of _Theologic_ science,--God's eternal justice and truth,--let us assert, that in the Divine government the matter of fact always determines the question of right, and that whatever has been done by him who rendereth no account to man of his matters, he had in all ages, and in all places, an unchallengeable right to do. The oldest known reptiles appear just a little before the close of the Old Red Sandstone, just as the oldest known fishes appeared just a little before the close of the Silurian System. What seems to be the Upper Old Red of our own country, though there still hangs a shade of doubt on the subject, has furnished the remains of a small reptile, equally akin, it would appear, to the lizards and the batrachians; and what seems to be the Upper Old Red of the United States has exhibited the foot-tracks of a larger animal of the same class, which not a little resemble those which would be impressed on recent sand or clay by the alligator of the Mississippi, did not the alligator of the Mississippi efface its own footprints (a consequence of the shortness of its legs) by the trail of its abdomen. In the Coal Measures, the reptiles hitherto found,--and it is still little more than ten years since the first was detected,--are all allied, though not without a cross of the higher crocodilian or lacertian nature, to the batrachian order,--that lowest order of the reptiles to which the frogs, newts, and salamanders belong. These reptiles of the carboniferous era, though only a few twelvemonths ago we little suspected the fact, seem to have been not very rare in our own neighborhood. My attention was called some time since by Mr. Henry Cadell,--an intelligent practical geologist,--to certain appearances in one of the Duke of Buccleuch's coal pits near Dalkeith, which lie regarded as the tracks of air-breathing quadrupeds; and, after examining a specimen, containing four footprints, which he had brought above ground, and which not a little excited my curiosity, we visited the pit together. And there, in a side working about half a mile from the pit mouth, and about four hundred feet under the surface, I found the roof of the coal, which rose at a high angle, traversed by so many foot-tracks, upwards, downwards, and athwart, that it cost me some little care to trace the individual lines. At least one of the number, however,--consisting of eleven footprints of the right and as many of the left foot--I was able to trace from side to side of the working, a distance of four yards; and several of the others for shorter spaces. The prints, which were reverses or casts in a very coarse sandstone, were about thirtecn inches apart across the creature's chest, and rather more than a foot apart from its fore to its hinder limbs. They were alternately larger and smaller,--the smaller (those of the fore feet) measuring about four inches in length, and the larger (those of the hinder feet) about six inches. The number of toes seemed to be alternately four and five; but from the circumstance that the original matrix on which the tracks had been impressed,--a micaceous clay resolved into a loose fissile sandstone,--had fallen away in the working of the pit, leaving but the boldly-relieved though ill-defined casts on the coarse sandstone, I could not definitely determine the point. Enough, however, remained to show that at that spot,--little more than a mile from where the Duke of Buccleuch's palace now stands,--large reptiles had congregated in considerable numbers shortly after the great eight feet coal seam of the Dalkeith basin had been formed. In another part of the pit I found foot-tracks of apparently the same animal in equal abundance, but still less distinct in their state of keeping. But they bore testimony with the others to the comparative abundance of reptilian life at an early period, when the coal-bearing strata of the empire were little more than half deposited. It was not, however, until the Permian and Triassic Systems had come to a close, and even the earlier ages of the Oolitic System had passed away, that the class received its fullest development in creation. And certainly very wonderful was the development which it then did receive. Reptiles became everywhere the lords and masters of this lower world. When any class of the air-breathing vertebrates is very largely developed, we find it taking possession of all the three old terrestrial elements,--earth, air, and water. The human period, for instance, like that which immediately preceded it, is peculiarly a period of mammals; and we find the class, _free_, if I may so express myself, of the three elements, disputing possession of the sea with the fishes, in its Cetaceans, its seals, and its sea-lions, and of the air with the birds, in its numerous genera of the bat family. Further, not until the great mammaliferous period is fairly ushered in do either the bats or the whales make their appearance in creation. Remains of Oolitic reptiles have been mistaken in more than one instance for those of Cetacea; but it is now generally held that the earliest known specimens of the family belong to the Tertiary ages, while those of the oldest bats occur in the Eocene of the Paris Basin, associated with the bones of dolphins, lamantines, and morses. Now, in the times of the Oolite it was the reptilian class that possessed itself of all the elements. Its gigantic enaliosaurs, huge reptilian _whales_ mounted on paddles, were the tyrants of the ocean, and must have reigned supreme over the already reduced class of fishes; its pterodactyles,--dragons as strange as were ever feigned by romancer of the middle ages, and that to the jaws and teeth of the crocodile added the wings of a bat and the body and tail of an ordinary mammal, had "the power of the air," and, pursuing the fleetest insects in their flight, captured and bore them down;[14] its lakes and rivers abounded in crocodiles and fresh water tortoises of ancient type and fashion; and its woods and plains were the haunts of a strange reptilian fauna, of what has been well termed "fearfully great lizards,"--some of which, such as the iguanodon, rivalled the largest elephant in height, and greatly more than rivalled him in length and bulk. Judging from what remains, it seems not improbable that the reptiles of this Oolitic period were quite as numerous individually, and consisted of well nigh as many genera and species, as all the mammals of the present time. In the cretaceous ages, the class, though still the dominant one, is visibly reduced in its standing; it had reached its culminating point in the Oolite, and then began to decline; and with the first dawn of the Tertiary division we find it occupying, as now, a very subordinate place in creation. Curiously enough, it is not until its times of humiliation and decay that one of the most remarkable of its orders appears,--an order itself illustrative of extreme degradation, and which figures largely, in every scheme of mythology that borrowed through traditional channels from Divine revelation, as a meet representative of man's great enemy the Evil One. I of course refer to the ophidian or serpent family. The earliest ophidian remains known to the Palæontologist occur in that ancient deposit of the Tertiary division known as the London Clay, and must have belonged to serpents, some of them allied to the Pythons, some to the sea-snakes, which, judging from the corresponding parts of recent species, must have been from fourteen to twenty feet in length. [Illustration: Fig. 61. VESPERTILIO PARISIENSIS. A Bat of the Eocene.] [Illustration: Fig. 62 ICHTHYOSAURUS COMMUNIS. (_Lias._)] [Illustration: Fig. 63. PLESIOSAURUS DOLICHODEIRUS. (_Lias._)] [Illustration: Fig. 64. PTERODACTYLUS CRASSIROSTRIS. (_Oolite._)] [Illustration: Fig. 65. CHELONIA BENSTEDI. (_Chalk._)] [Illustration: Fig. 66. PALÆOPHIS TOLIAPICUS. (_Ophidian of the Eocene._)] And here let us again pause for a moment, to remark how strangely these irascible, repulsive reptiles,--creatures lengthened out far beyond the proportions of the other members of their class by mere vegetative repetitions of the vertebræ,--condemned to derive, worm-like, their ability of progressive motion from the ring-like scutes of the abdomen--venomous in many of their species,--formidable in others to even the noblest animals, from their fascinating powers and their great craft,--without, fore or hinder limbs, without thoracic or pelvic arches,--the very types and exemplars (our highest naturalists being the judges) of the extreme of animal degradation,--let us, I say, remark how strangely their history has been mixed up with that of man and of religion in all the older mythologies, and in that Divine Revelation whence the older mythologies were derived. It was one of the most ancient of the Phoenician fables, that the great antagonist of the gods was a gigantic serpent, that had at one time been their subject, but revolted against them and became their enemy. It was a monstrous serpent that assailed and strove to destroy the _mother_ of Apollo ere yet the birth of the god, but which, long after, _Apollo_ in turn assaulted and slew. It was a great serpent that watched over the apples of the Hesperides, and that Hercules, ere he could possess himself of the fruit, had to combat and kill. It was a frightful serpent that guarded the golden fleece from Jason, and which the hero had to destroy in the first instance, and next to exterminate the strange brood of armed men that sprang up from its sown teeth. In short, the old mythologies are well nigh as full of the serpent as those ancient Runic obelisks of our country, whose endless knots and complicated fretwork are formed throughout of the interlacings of snakes. Let us, however, accept as representative of this innumerable class of legends, the classical story, rendered yet more classical by the profound and reverend comment given by Bacon in his "Wisdom of the Ancients." "Jupiter and the other gods," says the philosopher, in his simple version of the tradition, "conferred upon men a most acceptable and desirable boon,--the gift of perpetual youth. But men, foolishly overjoyed hereat, laid this present of the gods upon an ass, who, in returning back with it, being extremely thirsty, and coming to a fountain, the serpent who was guardian thereof would not suffer him to drink but upon condition of receiving the burden he carried, whatever it should be. The silly ass complied; and thus the perpetual renewal of youth was for a sup of water transferred from men to the race of serpents." "That this gift of perpetual youth should pass from men to serpents," continues Bacon, "seems added, by way of ornament and illustration, to the fable." And it certainly _has_ much the appearance of an after-thought. But how very striking the resemblance, borne by the story, as a whole, to that narrative in the opening page of human history which exhibits the first parents of the race as yielding up to the temptation of the serpent the gift of immortality; and further, how remarkable the fact, that the reptile selected as typical here of the great fallen spirit that kept not his first estate, should be at once the reptile of latest appearance in creation, and the one selected by philosophical naturalists as representative of a reversed process in the course of being,--of a downward, sinking career, from the vertebrate antetype towards greatly lower types in the invertebrate divisions! The fallen spirit is represented in revelation by what we are now taught to recognize in science as a _degraded_ reptile. [Illustration: Fig. 67. BIRD TRACKS OF THE CONNECTICUT. (_Lias or Oolite._)] [Illustration: Fig. 68. FOSSIL FOOTPRINT. Connecticut.] Birds make their first appearance in a Red Sandstone deposit of the United States in the valley of the Connecticut, which was at one time supposed to belong to the Triassic System, but which is now held to be at least not older than the times of the Lias. No fragments of the skeletons of birds have yet been discovered in formations older than the Chalk: the Connecticut remains are those of footprints exclusively; and yet they tell their extraordinary story, so far as it extends, with remarkable precision and distinctness. They were apparently all of the Grallæ or stilt order of birds,--an order to which the cranes, herons, and bustards belong, with the ostriches and cassowaries, and which is characterized by possessing but three toes on each foot (one species of ostrich has but two), or, if a fourth toe be present, so imperfectly is it developed in most of the cases, that it fails to reach the ground. And in almost all the footprints of the primeval birds of the Connecticut there are only three toes exhibited. Peculiar, ill understood laws regulate the phalangal divisions of the various animals. It is a law of the human kind, for instance, that the thumb should consist of but three phalanges; while the fingers, even the smallest, consist of four. And, in the same way, it is a law generally exemplified among birds, that of the three toes which correspond to the fingers, the inner toe should be composed of three phalanges, the middle or largest toe of four phalanges, and the outer toe, though but second in point of size, of five phalanges. Such is the law now, and such was equally the law, as shown by the American footprints, in the times of the Lias. Some of the impressions are of singular distinctness. Every claw and phalange has left its mark in the stone; while the trifid termination of the tarso-metatarsal bone leaves three marks more,--fifteen in all,--the true ornithic number. In some of the specimens even the pressure of a metatarsal brush, still possessed by some birds, is distinctly traceable; nay, there are instances in which the impress of the dermoid papillæ has remained as sharply as if made in wax. But the immense size of some of these footprints served to militate for a time against belief in their ornithic origin. The impressions that are but secondary in point of size greatly exceed those of the hugest birds which now exist; while those of the largest class equal the prints of the bulkier quadrupeds. There are tridactyle footprints in the red sandstones of Connecticut that measure eighteen inches in length from the heel to the middle claw, nearly thirteen inches in breadth from the outer to the inner toe, and which indicate, from their distance apart in the straight line, a stride of about six feet in the creature that impressed them in these ancient sands,--measurements that might well startle zoologists who had derived their experience of the ornithic class from existing birds exclusively. Comparatively recent discoveries have, however, if not lessened, at least familiarized us to the wonder. In a deposit of New Zealand that dates little if at all in advance of the human period, there have been detected the remains of birds scarce inferior in size to those of America in the Liassic ages. The bones of the _Dinornus giganteus_, exhibited by the late Dr. Mantell in Edinburgh in the autumn of 1850, greatly exceeded in bulk those of the largest horse. A thigh bone sixteen inches in length measured nearly nine inches in circumference in the middle of the shaft: the head of a tibia measured twenty-one inches in circumference. It was estimated that a foot entire in all its parts, which formed an interesting portion of the exhibition, would, when it was furnished with nails, and covered by the integuments, have measured about fifteen inches in length; and it was calculated by a very competent authority, Professor Owen, that of the other bones of the leg to which it belonged, the tibia must have been about two feet nine inches, and the femur about fourteen and a half inches long. The larger thigh bone referred to must have belonged, it was held, to a bird that stood from eleven to twelve feet high,--the extreme height of the great African elephant. Such were the monster birds of a comparatively recent period; and their remains serve to render credible the evidence furnished by the great footprints of their remote predecessors of the Lias. The huge feet of the greatest Dinornus whose bones have yet been found would have left impressions scarcely an inch shorter than those of the still huger birds of the Connecticut. Is it not truly wonderful, that in this late age of the world, in which the invention of the poets seems to content itself with humbler and lowlier flights than of old, we should thus find the facts of geology fully rivalling, in the strange and the _outré_, the wildest fancies of the romancers who flourished in the middle ages? I have already referred to flying dragons,--real existences of the Oolitic period,--that were quite as extraordinary of type, if not altogether so huge of bulk, as those with which the Seven Champions of Christendom used to do battle; and here are we introduced to birds of the Liassic ages that were scarce less gigantic than the roc of Sinbad the Sailor. They are fraught with strange meanings these footprints of the Connecticut. They tell of a time far removed into the by-past eternity, when great birds frequented by myriads the shores of a nameless lake, to wade into its shallows in quest of mail-covered fishes of the ancient type, or long-extinct molluscs; while reptiles equally gigantic, and of still stranger proportions, haunted the neighboring swamps and savannahs; and when the same sun that shone on the tall moving forms beside the waters, and threw their long shadows across the red sands, lighted up the glades of deep forests, all of whose fantastic productions,--tree, bush, and herb,--have even in their very species long since passed away. And of this scene of things only the footprints remain,--"footprints on the sands of time," that tell us, among other matters, whence the graceful American poet derived his quiet but singularly effective and unmistakeably indigenous figure:-- "Lives of great men all remind us We can make our lives sublime, _And, departing, leave behind us_ _Footprints on the sand of time._ Footprints that perhaps another, Sailing o'er life's solemn main, A forlorn and shipwrecked brother, Seeing, shall take heart again." [Illustration: Fig. 69. THYLACOTHERIUM PREVOSTI. (_Stonisfield Slate._)] With the Stonisfield slates,--a deposit which lies above what is known as the Inferior Oolite,--the remains of mammaliferous animals first appear. As, however, no other mammalian remains occur until after the close of the great Secondary Division, and as certain marked peculiarities attach to these Oolitic ones, it may be well to inquire whether their place, so far in advance of their fellows, may not be indicative of a radical difference of character,--a difference considerable enough to suggest to the zoologist an improvement in his scheme of classification. It has been shown by Professor Owen,--our highest authority in comparative anatomy,--that while one Stonisfield genus unequivocally belonged to the marsupial order, another of its genera bears also certain of the marsupial traits; and that the group which they composed,--a very small one, and consisting exclusively of minute insect-eating animals,--exhibits in its general aspect the characteristics of this pouched family. Even the genus of the group that least resembles them was pronounced by Cuvier to have its nearest affinities with the opossums. And let us mark how very much may be implied in this circumstance. In the "_Animal Kingdom_" of the great naturalist just named, the marsupiata, or pouched animals, are made to occupy the fourth place among the nine orders of the Mammalia; but should they not rather occupy a place intermediate between the placental mammals and the birds? and does not nature indicate their true position by the position which she assigns to them in the geologic scale? The birds are oviparous; and between the extrusion of the egg and the development of the perfect young bird they have to hatch it into life during a long period of incubation. The marsupiata are not oviparous, for their _eggs_ want the enveloping shell or skin; but they, too, are extruded in an exceedingly rudimentary and foetal state, and have to undergo in the pouch a greatly longer period of _incubation_ than that demanded by nature for any bird whatever. The young kangaroo is extruded, after it has remained for little more than a month in the womb, as a foetus scarcely an inch in length by somewhat less than half an inch in breadth: it is blind, exhibiting merely dark eye spots; its limbs are so rudimentary, that even the hinder legs, so largely developed in the genus when mature, exist as mere stumps; it is unable even to suck, but, holding permanently on by a minute dug, has the sustaining fluid occasionally pressed into its mouth by the mother. And, undergoing a peculiar but not the less real process of incubation, the creature that had to remain for little more than a month in the womb,--strictly thirty-nine days,--has to remain in the mother's pouch, ere it is fully developed and able to provide for itself, for a period of eight months. It is found to increase in weight during this hatching process, from somewhat less than an ounce to somewhat more than eight pounds. Now, this surely is a process quite as nearly akin to the incubation of egg-bearing birds as to the ordinary nursing process of the placental mammals; and on the occult but apparently real principle, that the true arrangement of the animal kingdom is that which we find exemplified by the successive introduction of its various classes and orders in the course of geologic history, should we not anticipate a point of time for the introduction of the marsupiata, intermediate between the widely-distant points at which the egg-bearing birds and the true placental mammals appeared? Ranged at once chronologically, and by their mode of reproduction, the various classes of the vertebrata would run, did we accept the suggested reading, as follows:--First appear cold-blooded vertebrates (fishes), that propagate by eggs or spawn,--chiefly by the latter. Next appear cold-blooded vertebrates (reptiles), that propagate by eggs or spawn,--chiefly by the former. Then appear warm-blooded vertebrates (birds), that propagate by eggs exclusively. Then warm-blooded vertebrates come upon the stage, that produce _eggs_ without shells, which have to be subjected for months to a species of extra-placental incubation. And last of all the true placental mammals appear. And thus, tried by the test of perfect reproduction, the great vertebral division receives its full development in creation. [Illustration: Fig. 70. ANOPLTHERIUM COMMUNE. (_Eocene._)] The placental mammals make their appearance, as I have said, in the earliest ages of the great Tertiary division, and exhibit in the group an aspect very unlike that which they at present bear. The Eocene ages were peculiarly the ages of the Palæotheres,--strange animals of that pachydermatous or thick-skinned order to which the elephants, the tapirs, the hogs, and the horses belong. It had been remarked by naturalists, that there are fewer families of this order in living nature than of almost any other, and that, of the existing genera, not a few are widely separated in their analogies from the others. But in the Palæotheres of the Eocene, which ranged in size from a large horse to a hare, not a few of the missing links have been found,--links connecting the tapirs to the hogs, and the hogs to the Palæotheres proper; and there is at least one species suggestive of an union of some of the more peculiar traits of the tapirs and the horses. It was among these extinct Pachydermata of the Paris basin that Cuvier effected his wonderful restorations, and produced those figures in outline which are now as familiar to the geologist as any of the forms of the existing animals. The London Clay and the Eocene of the Isle of Wight have also yielded numerous specimens of those pachyderms, whose identity with the Continental ones has been established by Owen; but they are more fragmentary, and their state of keeping less perfect, than those furnished by the gypsum quarries of Velay and Montmartre. In these the smaller animals occur often in a state of preservation so peculiar and partial as to excite the curiosity of even the untaught workmen. Only half the skeleton is present. The limbs and ribs of the under side are found lying in nearly their proper places; while of the limbs and ribs of the upper side usually not a trace can be detected,--even the upper side of the skull is often awanting. It-would almost seem as if some pre-Adamite butcher had divided the carcasses longitudinally, and carried away with him all the upper halves. The reading of the enigma seems to be, that when the creatures lay down and died, the gypsum in which their remains occur was soft enough to permit their under sides to sink into it, and that then gradually hardening, it kept the bones in their places; while the uncovered upper sides, exposed to the disintegrating influences, either mouldered away piecemeal, or were removed by accident. The bones of the larger animals of the basin are usually found detached; and ere they could be reconstructed into perfect skeletons, they taxed the extraordinary powers of the greatest of comparative anatomists. Rather more than twenty different species of extinct mammals have been detected in the Paris basin,--not a great number, it may be thought; and yet for so limited a locality we may deem it not a very small one, when we take into account the fact that all our native mammals of Britain and Ireland amount (according to Fleming), if we except the Cetaceæ and the seals, to but forty species. [Illustration: Fig 71. ANIMALS OF THE PARIS BASIN.[15] (_Eocene._)] [Illustration: Fig. 72. DINOTHERIUM GIGANTEUM. (_Miocene._)] In the Middle or Miocene Tertiary, pachyderms, though of a wholly different type from their predecessors, are still the prevailing forms. The Dinotherium, one of the greatest quadrupedal mammals that ever lived, seems to have formed a connecting link in this middle age between the Pachydermata and the Cetaceæ. Each ramus of the under jaw, which in the larger specimens are fully four feet in length, bore at the symphysis a great bent tusk turned downwards, which appears to have been employed as a pickaxe in uprooting the aquatic plants and liliaceous roots on which the creature seems to have lived. The head, which measured about three feet across,--a breadth, sufficient, surely, to satisfy the demands of the most exacting phrenologist,--was provided with muscles of enormous strength, arranged so as to give potent effect to the operations of this strange tool. The hinder part of the skull not a little resembled that of the Cetaceæ; while, from the form of the nasal bones, the creature was evidently furnished with a trunk like the elephant. It seems not improbable, therefore, that this bulkiest of mammaliferous quadrupeds constituted, as I have said, a sort of uniting tie between creatures still associated in the human mind, from the circumstance of their massive proportions, as the greatest that swim the sea or walk the land,--the whale and the elephant. The Mastodon, an elephantoid animal, also furnished, like the elephant, with tusks and trunk, but marked by certain peculiarities which constitute it a different genus, seems in Europe to have been contemporary with the Dinotherium; but in North America (the scene of its greatest numerical development) it appears to belong to a later age. In height it did not surpass the African elephant, but it considerably exceeded it in length,--a specimen which could not have stood above twelve feet high indicating a length of about twenty-five feet: it had what the elephants want,--tusks fixed in its lower jaw, which the males retained through life, but the females lost when young; its limbs were proportionally shorter, but more massive, and its abdomen more elongated and slim; its grinder teeth too, some of which have been known to weigh from seventeen to twenty pounds, and their cusps elevated into great mammæ-like protuberances, to which the creature owes its name, and wholly differ in their proportions and outline from the grinders of the elephant. The much greater remoteness of the mastodonic period in Europe than in America is a circumstance worthy of notice, as it is one of many facts that seem to indicate a general transposition of at least the later geologic ages on the opposite sides of the Atlantic. Groups of corresponding character on the eastern and western shores of this great ocean were not contemporaneous in time. It has been repeatedly remarked, that the existing plants and trees of the United States, with not a few of its fishes and reptiles, bear in their forms and construction the marks of a much greater antiquity than those of Europe. The geologist who sets himself to discover similar types on the eastern side of the Atlantic would have to seek for them among the deposits of the later Tertiaries. North America seems to be still passing through its later Tertiary ages; and it appears to be a consequence of this curious transposition, that while in Europe the mastodonic period is removed by two great geologic eras from the present time, it is removed from it in America by only one. Even in America, however, that period lies far beyond the reach of human tradition,--a fact borne out by the pseudo-traditions retailed by the aborigines regarding the mastodon. By none of at least the higher naturalists has there been a doubt entertained respecting its herbivorous character; and the discovery of late years of the stomach of an individual charged with decayed herbage and fragments of the succulent branches of trees, some of them of existing species, has demonstrated the solidity of the reasonings founded on its general structure and aspect. The pseudo-traditions, however, represent it in every instance as a carnivorous tyrant, that, had it not been itself destroyed, would have destroyed all the other animals its contemporaries. It is said by the red men of Virginia, "that a troop of these tremendous quadrupeds made fearful havoc for some time among the deer, the buffaloes, and all the other animals created for the use of the Indians, and spread desolation far and wide. At last '_the Mighty Man above_' seized his thunder and killed them all, with the exception of the largest of the males, who presenting his head to the thunderbolts, shook them off as they fell; but, being wounded in the side, he betook himself to flight towards the great lakes, where he still resides at the present day." Let me here remind you in the passing, that that antiquity of type which characterizes the recent productions of North America is one of many wonders,--not absolutely geological in themselves, but which, save for the revelations of geology, would have forever remained unnoted and unknown,--which have been pressed, during the last half century, on the notice of naturalists. "It is a circumstance quite extraordinary and unexpected," says Agassiz, in his profoundly interesting work on Lake Superior, "that the fossil plants of the Tertiary beds of Oeningen resemble more closely the trees and shrubs which grow at present in the eastern parts of North America, than those of any other parts of the world; thus allowing us to express correctly the difference between the opposite coasts of Europe and America, by saying that the present eastern American flora, and, I may add, the fauna also, have a more ancient character than those of Europe. The plants, especially the trees and shrubs, growing in our days in the United States, are, as it were, old-fashioned; and the characteristic genera Lagomys, Chelydra, and the large Salamanders with permanent gills, that remind us of the fossils of Oeningen, are at least equally so;--they bear the marks of former ages." How strange a fact! Not only are we accustomed to speak of the eastern continents as the Old World, in contradistinction to the great continent of the west, but to speak also of the world before the Flood as the Old World, in contradistinction to the post-diluvian world which succeeded it. And yet equally, if we receive the term in either of its acceptations, is America an older world still,--an older world than that of the eastern continents,--an older world, in the fashion and type of its productions, than the world before the Flood. And when the immigrant settler takes axe amid the deep backwoods, to lay open for the first time what he deems a new country, the great trees that fall before him,--the brushwood that he lops away with a sweep of his tool,--the unfamiliar herbs which he tramples under foot,--the lazy fish-like reptile that scarce stirs out of his path as he descends to the neighboring creek to drink,--the fierce alligator-like tortoise, with the large limbs and small carpace, that he sees watching among the reeds for fish and frogs, just as he reaches the water,--and the little hare-like rodent, without a tail, that he startles by the way,--all attest, by the antiqueness of the mould in which they are cast, how old a country the seemingly new one really is,--a country vastly older, in type at least, than that of the antediluvians and the patriarchs, and only to be compared with that which flourished on the eastern side of the Atlantic long ere the appearance of man, and the remains of whose perished productions we find locked up in the _loess_ of the Rhine, or amid the lignites of Nassau. America is emphatically the _Old_ World. If we accept, however, as sound the ingenious logic by which Colton labors to show, in not inelegant verse, that the _Moderns_ are the true _Ancients_, we may continue to term it the New World still. "We that on these late days are thrown Must be the oldest Ancients known; The _earliest_ Modern earth hath seen Was Adam in his apron green. He lived when young Creation pealed Her morning hymn o'er flood and field, Till all her infant offspring came To that great christening for a name. And he that would the Ancients know, Must forward come, not backward go: The learned lumber of the shelves Shows nothing older than ourselves. But who in older times than we Shall live?--That infant on the knee,-- See sights to us were never shown, And secrets known to us unknown." [Illustration: Fig. 73. ELEPHAS PRIMIGENIUS. (_Mammoth._) Great British Elephant.] [Illustration: Fig. 74. TROGONTHERIUM CUVIERI. Gigantic Beaver. (_Pleistocene._)] [Illustration: Fig. 75. URSUS SPELÆUS. Cave Bear. (_Pleistocene._)] [Illustration: Fig. 76. HYENA SPELÆA. Cave Hyæna. (_Pleistocene._)] The group of mammals which, in Europe, at least, immediately preceded the human period seems to have been everywhere a remarkable one; and nowhere was it more so than in the British islands. Our present mammaliferous fauna is rather poor; but the contents of the later deposits show that we must regard it as but a mere fragment of a very noble one. Associated with species that still exist in the less cultivated parts of the country, such as the badger, the fox, the wild cat, the roe and the red deer, we find the remains of great animals, whose congeners must now be sought for in the intertropical regions. Britain, during the times of the boulder clay, and for ages previous, had its native elephant, its two species of rhinoceros, its hippopotamus, its hyæna, its tiger, its three species of bears, its two species of beavers, its great elk, and its gigantic deer. Forms now found widely apart, and in very different climates, meet within the British area. During at least the earlier times of the group, the temperature of our island seems to have been very much what it is now. As I have already had occasion to remark, the British oak flourished on its plains and lower slopes, and the birch and Scotch fir on its hills. And yet under these familiar trees the lagomys or tailless hare, a form now mainly restricted to Siberia and the wilds of Northern America, and the reindeer, an animal whose proper habitat at the present time is Lapland, were associated with forms that are now only to be found between the tropics, such as that of the hippopotamus and rhinoceros. These last, however, unequivocally of extinct species, seem to have been adapted to live in a temperate climate; and we know from the famous Siberian specimen, that the British elephant, with its covering of long hair and closely-felted wool, was fitted to sustain the rigors of a very severe one. It is surely a strange fact, but not less true than strange, that since hill and dale assumed in Britain their present configuration, and the oak and birch flourished in its woods, there were caves in England haunted for ages by families of hyænas,--that they dragged into their dens with the carcasses of long extinct animals those of the still familiar denizens of our hill-sides, and feasted, now on the lagomys, and now on the common hare,--that they now fastened on the beaver or the reindeer, and now upon the roebuck or the goat. In one of these caves, such of the bones as projected from the stiff soil have been actually worn smooth in a narrow passage where the hyænas used to come in contact with them in passing out and in; and for several feet in depth the floor beneath is composed almost exclusively of gnawed fragments, that still exhibit the deeply indented marks of formidable teeth. In the famous Kirkdale cave alone, parts of the skeletons of from two to three hundred hyænas have been detected, mixed with portions of the osseous framework of the cave-tiger, the cave-bear, the ox, the deer, the mammoth, and the rhinoceros. That cave must have been a den of wild creatures for many ages ere the times of the boulder clay, during which period it was shut up from all access to the light and air by a drift deposit, and lay covered over until again laid open by some workmen little more than thirty years ago. Not only were many of the wild animals of the country which still exist contemporary for a time with its extinct bears, tigers, and elephants, but it seems at least highly probable that several of our domesticated breeds derived their origin from progenitors whose remains we find entombed in the bone-caves and other deposits of the same age; though of course the changes effected by domestication in almost all the tame animals renders the question of their identity with the indigenous breeds somewhat obscure. Cuvier was, however, unable to detect any difference between the skeleton of a fossil horse, contemporary with the elephant, and that of our domestic breed: a fossil goat of the same age cannot be distinguished from the domesticated animal; and one of our two fossil oxen (_Bos longifrons_) does not differ more from some of the existing breeds than these have, in the course of time, been made, chiefly by artificial means, to differ among themselves. But of one of our domestic tribes no trace has yet been found in the rocks: like the cod family among fishes, or the Rosaceæ among plants, it seems to have preceded man by but a very brief period. And certainly, if created specially for his use, though the pride of the herald might prevent him from selecting it as in aught typical of the human race, it would yet not be easy to instance a family of animals that has ministered more extensively to his necessities. I refer to the sheep,--that soft and harmless creature, that clothes civilized man everywhere in the colder latitudes with its fleece,--that feeds him with its flesh,--that gives its bowels to be spun into the catgut with which he refits his musical instruments,--whose horns he has learned to fashion into a thousand useful trinkets,--and whose skin, converted into parchment, served to convey to later times the thinking of the first full blow of the human intellect across the dreary gulf of the middle ages. At length the human period begins. A creature appears upon the scene unlike all that had preceded him, and whose nature it equally is to look back upon the events of the past,--among other matters, on that succession of beings upon the planet which he inhabits, with which we are this evening attempting to deal,--and to anticipate at least one succession more, in that still future state in which he himself is again to appear, in happier circumstances than now, and in a worthier character. We possess another history of the primeval age and subsequent chronology of the human family than that which we find inscribed in the rocks. And it is well that we do so. From various causes, the geologic evidence regarding the period of man's first appearance on earth is singularly obscure. That custom of "burying his dead out of his sight," which obtained, we know, in the patriarchal times, and was probably in use ever since man came first under the law of death, has had the effect of mingling his remains with those of creatures that were extinct for ages ere he began to be. The cavern, once a haunt of carnivorous animals, that in the first simple ages of his history had furnished him with a shelter when living, became his burying-place when dead; and thus his bones, and his first rude attempts in pottery and weapon-making, have been found associated with the remains of the cave-hyæna and cave-tiger, with the teeth of the ancient hippopotamus, and the tusks of the primeval elephant. The evidence on the point, too,--from the great paucity of human remains of a comparatively remote period, and from the circumstance that they are rarely seen by geologists in the stratum in which they occur,--is usually very imperfect in its details. Further, it is an evidence obnoxious to suspicion, from the fact that a keen controversy has arisen on the subject of man's antiquity, that such fragments of man himself or of his works as manifest great age have been pressed to serve as weapons in the fray,--that, occurring always in superficial and local deposits, their true era may be greatly antedated, under the influence of prejudice, by men who have no design wilfully to deceive,--and that while, respecting the older formations, with their abundant organisms, the conclusions of any one geologist may be tested by all the others, the geologist who once in a lifetime picks up in a stratified sand or clay a stone arrow-head or a human bone, finds that the data on which he founds his conclusions may be received or rejected by his contemporaries, but not re-examined. It may be safely stated, however, that that ancient record in which man is represented as the lastborn of creation, is opposed by no geologic fact; and that if, according to Chalmers, "the Mosaic writings do not fix the antiquity of the globe," they at least _do_ fix--making allowance, of course, for the varying estimates of the chronologer--"the antiquity of the human species." The great column of being, with its base set in the sea, and inscribed, like some old triumphal pillar, with many a strange form,--at once hieroglyphic and figure,--bears, as the ornately sculptured capital, which imparts beauty and finish to the whole, reasoning, responsible man. There is surely a very wonderful harmony manifested in the proportions of that nice sequence in which the invertebrates--the fishes, the reptiles, the birds, the marsupials, the placental mammals, and, last of all, man himself--are so exquisitely arranged. It reminds us of the fine figure employed by Dryden in his first Ode for St. Cecilia's Day,--a figure which, viewed in the light cast on it by the modern science of Palæontology, stands out in bolder relief than that in which it could have appeared to the poet himself:-- "From harmony, from heavenly harmony, This universal frame began; From harmony to harmony, Through all the compass of the notes it ran, The _diapason_ closing full in man." [Illustration: Fig. 77. ASAPHUS CAUDATUS. (_Silurian._)] [Illustration: Fig. 78. ORTHOCERAS LATERALE. (_Mountain Limestone._)] [Illustration: Fig. 79. SPIRIGERINA RETICULARIS. (_Old Red Sandstone._)] [Illustration: Fig. 80. A. MARGARITATUS. (_Lias._)] [Illustration: Fig. 81. A. BISULCATUS. (_Lias._)] [Illustration: Fig. 82. BELEMNITELLA MUCRONATA. (_Chalk._)] [Illustration: Fig. 83. BELEMNITES SULCATUS. (_Oolite._)] In the limits to which I have restricted myself, I have been able to do little more than simply to chronicle the successive eras in which the various classes and divisions of the organic kingdom, vegetable and animal, make their appearance in creation. I have produced merely a brief record of the various births, in their order, of that great family whose father is God. And in pursuing such a plan, much, of necessity, must have been omitted. I ought perhaps to have told you, that very rarely, if ever, do the master forms of a period constitute the prevailing or typical organisms of its deposits. Of the three great divisions of which the geologic scale consists,--Palæozoic, Secondary, and Tertiary,--the first, or ichthyic period, is marked chiefly, not by its great fishes, but by the peculiar character of its brachipodous and cephalopodous mollusca, and in its earlier stages by its three-lobed crustaceæ; the second or reptilian period was emphatically the period of the ammonite and belemnite; while the third and last, or mammalian period, was that of gastropodous and conchiferous molluscs, impressed, generically at least, by all the features of the group which still exists in our seas. Save in a few local deposits, fishes do not form the prevailing organisms in the formations of the age of fishes; nor reptiles in the formations of the age of reptiles; nor yet mammals in the formations of the age of mammals. Nay, it is not improbable that the recent or human period may be marked most prominently in the future, when it comes to exist simply as a geologic system, by a still humbler organism than most of these molluscs. On almost all rocky shores a line of pale gray may be seen at low water, running for mile after mile along the belt that has been laid bare at the bases of the cliffs by the fall of the tide. It owes its pale color to millions of millions of a small balanus (_B. balanoides_), produced in such amazing abundance in the littoral zone as to cover with a rough crust every minute portion of rock and every sedentary shell. Other species of the same genus (_B. crenatus_ and _B. porcatus_) occupy the depths of the sea beyond; and their remains, washed ashore by the waves, and mingled with those of the littoral species, form often great accumulations of shell sand. I have seen among the Hebrides a shell sand accumulated along the beach to the depth of many feet, of which fully two thirds was composed of the valves and compartments of balanidæ; and a similar sand on the east coast of Scotland, a little to the south of St. Andrews, formed in still larger proportions of the fragments of a single species,--_Balanus crenatus_. Now, this genus, so amazingly abundant at the present time in every existing sea, and whose accumulated remains bid fair to exist as great limestone rocks in the future, had no existence in the Palæozoic or Secondary ages. It first appears in the times of the earlier Tertiary, in, however, only a single species; and, becoming gradually of more and more importance as a group, it receives its fullest numerical development in the present time. And thus the remains of a sub-class of animals, low in their standing among the articulata, may form one of the most prominent Palæontological features of the human period. But enough for the present of circumstance and detail. [Illustration: Fig. 84. MUREX ALVEOLATUS. (_Red Crag._)] [Illustration: Fig. 85. ASTARTE OMALII. (_Red Crag._)] [Illustration: Fig. 86. BALANUS CRASSUS. (_Red Crag._)] Such, so far as the geologist has yet been able to read the records of his science, has been the course of creation, from the first beginnings of vitality upon our planet, until the appearance of man. And very wonderful, surely, has that course been! How strange a procession! Never yet on Egyptian obelisk or Assyrian frieze,--where long lines of figures seem stalking across the granite, each charged with symbol and mystery,--have our Layards or Rawlinsons seen aught so extraordinary as that long procession of being which, starting out of the blank depths of the bygone eternity, is still defiling across the stage, and of which we ourselves form some of the passing figures. Who shall declare the profound meanings with which these geologic hieroglyphics are charged, or indicate the ultimate goal at which the long procession is destined to arrive? The readings already given, the conclusions already deduced, are as various as the hopes and fears, the habits of thought, and the cast of intellect, of the several interpreters who have set themselves,--some, alas! with but little preparation and very imperfect knowledge,--to declare in their order the details of this marvellous, dream-like vision, and, with the dream, "the interpretation thereof." One class of interpreters may well remind us of the dim-eyed old man,--the genius of unbelief so poetically described by Coleridge,--who, sitting in his cold and dreary cave, "talked much and vehemently concerning an infinite series of causes and effects, which he explained to be a string of blind men, the last of whom caught hold of the skirt of the one before him, he of the next, and so on, till they were all out of sight, and that they all walked infallibly straight, without making one false step, though all were alike blind." With these must I class those assertors of the development hypothesis who can see in the upward progress of being only the operations of an incomprehending and incomprehensible law, through which, in the course of unreckoned ages, the lower tribes and families have risen into the higher, and inferior into superior natures, and in virtue of which, in short, the animal creation has grown, in at least its nobler specimens, altogether unwittingly, without thought or care on its own part, and without intelligence on the part of the operating law, from irrational to rational, and risen in the scale from the mere promptings of instinct to the highest exercise of reason,--from apes and baboons to Bacons and Newtons. The blind lead the blind;--the unseeing law operates on the unperceiving creatures; and they go, not together into the ditch, but direct onwards, straight as an arrow, and higher and higher at every step. Another class look with profound melancholy on that great city of the dead,--the burial-place of all that ever lived in the past,--which occupies with its ever-extending pavements of gravestones, and its ever-lengthening streets of tombs and sepulchres, every region opened up by the geologist. They see the onward procession of being as if but tipped with life, and nought but inanimate carcasses all behind,--dead individuals, dead species, dead genera, dead creations,--a universe of death; and ask whether the same annihilation which overtook in turn all the races of all the past, shall not one day overtake our own race also, and a time come when men and their works shall have no existence save as stone-pervaded fossils locked up in the rock forever? Nowhere do we find the doubts and fears of this class more admirably portrayed than in the works of perhaps the most thoughtful and suggestive of living poets:-- "Are God and Nature then at strife, That Nature lends such evil dreams, So careful of the type she seems, So careless of the single life? 'So careful of the type!' but no, From scarped cliff and quarried stone, She cries, 'A thousand types are gone; I care for nothing; all shall go: Thou makest thine appeal to me; I bring to life, I bring to death; The spirit does but mean the breath. I know no more.' And he,--shall he, Man, her last work, who seemed so fair, Such splendid purpose in his eyes, Who rolled the psalm to wintry skies And built him fanes of fruitless prayer, Who trusted God was love indeed, And love creation's final law, Though Nature, red in tooth and claw, With ravine shrieked against his creed,-- Who loved, who suffered countless ills, Who battled for the true, the just,-- Be blown about the desert dust, Or sealed within the iron hills? No more!--a monster then, a dream, A discord. Dragons of the prime, That tore each other in their slime, Were mellow music matched with him. O, life, as futile then as frail,-- O for thy voice to soothe and bless! What hope of answer or redress, Behind the vail, behind the vail!" The sagacity of the poet here,--that strange sagacity which seems so nearly akin to the prophetic spirit,--suggests in this noble passage the true reading of the enigma. The appearance of man upon the scene of being constitutes a new era in creation; the operations of a new _instinct_ come into play,--that _instinct_ which anticipates a life after the grave, and reposes in implicit faith upon a God alike just and good, who is the pledged "rewarder of all who diligently seek Him." And in looking along the long line of being,--ever rising in the scale from higher to yet higher manifestations, or abroad on the lower animals, whom instinct never deceives,--can we hold that man, immeasurably higher in his place, and infinitely higher in his hopes and aspirations, than all that ever went before him, should be, notwithstanding, the one grand error in creation,--the one painful worker, in the midst of present trouble, for a state into which he is never to enter,--the befooled expectant of a happy future, which he is never to see? Assuredly no. He who keeps faith with all his humbler creatures,--who gives to even the bee and the dormouse the winter for which they prepare,--will to a certainty not break faith with man,--with man, alike the deputed lord of the present creation, and the chosen heir of all the future. We have been looking abroad on the old geologic burying-grounds, and deciphering the strange inscriptions on their tombs; but there are other burying-grounds, and other tombs,--solitary churchyards among the hills, where the dust of the martyrs lies, and tombs that rise over the ashes of the wise and good; nor are there awanting, on even the monuments of the perished races, frequent hieroglyphics, and symbols of high meaning, which darkly intimate to us, that while _their_ burial-yards contain but the debris of the past, we are to regard the others as charged with the sown seed of the future. LECTURE THIRD. THE TWO RECORDS, MOSAIC AND GEOLOGICAL. It is now exactly fifty years since a clergyman of the Scottish Church, engaged in lecturing at St. Andrews, took occasion in enumerating the various earths of the chemist, to allude to the science, then in its infancy, that specially deals with the rocks and soils which these earths compose. "There is a prejudice," he remarked, "against the speculations of the geologist, which I am anxious to remove. It has been said that they nurture infidel propensities. It has been alleged that geology, by referring the origin of the globe to a higher antiquity than is assigned to it by the writings of Moses, undermines our faith in the inspiration of the Bible, and in all the animating prospects of the immortality which it unfolds. This is a false alarm. _The writings of Moses do not fix the antiquity of the globe._" The bold lecturer on this occasion,--for it needed no small courage in a divine of any Established Church to take up, at the beginning of the present century, a position so determined on the geologic side,--was at the time an obscure young man, characterized, in the small circle in which he moved, by the ardor of his temperament and the breadth and originality of his views; but not yet distinguished in the science or literature of his country, and of comparatively little weight in the theological field. He was marked, too, by what his soberer acquaintance deemed eccentricities of thought and conduct. When the opposite view was all but universal, he held and taught that free trade would be not only a general benefit to the people of this country, but would inflict permanent injury on no one class or portion of them; and further, at a time when the streets and lanes of all the great cities of the empire were lighted with oil burnt in lamps, he held that the time was not distant when a carburetted hydrogen gas would be substituted instead; and, on getting his snug parsonage-house repaired, he actually introduced into the walls a system of tubes and pipes for the passage into its various rooms of the gaseous fluid yet to be employed as the illuminating agent. Time and experience have since impressed their stamp on these supposed eccentricities, and shown them to be the sagacious forecastings of a man who saw further and more clearly than his contemporaries; and fame has since blown his name very widely, as one of the most comprehensive and enlightened, and, withal, one of the most thoroughly earnest and sincere, of modern theologians. The bold lecturer of St. Andrews was Dr. Thomas Chalmers,--a divine whose writings are now known wherever the English language is spoken, and whose wonderful eloquence lives in memory as a vanished power, which even his extraordinary writings fail adequately to represent. And in the position which he took up at this early period with respect to geology and the Divine Record, we have yet another instance of the great sagacity of the man, and of his ability of correctly estimating the prevailing weight of the evidence with which, though but partially collected at the time, the geologist was preparing to establish the leading propositions of his science. Even in this late age, when the scientific standing of geology is all but universally recognized, and the vast periods of time which it demands fully conceded, neither geologist nor theologian, could, in any new scheme of reconciliation, shape his first proposition more skilfully than it was shaped by Chalmers a full half century ago. It has formed since that time the preliminary proposition of those ornaments of at once science and the English Church, the present venerable Archbishop of Canterbury, Dr. Bird Sumner, with Doctors Buckland, Conybeare, and Professor Sedgwick; of eminent evangelistic Dissenters too, such as the late Dr. Pye Smith, Dr. John Harris, Dr. Robert Vaughan, Dr. James Hamilton, and the Rev. Mr. Binney,--enlightened and distinguished men, who all came early to the conclusion, with the lecturer of St. Andrews, that "the writings of Moses do not fix the antiquity of the globe." In 1814, ten years after the date of the St. Andrews' lectures, Dr. Chalmers produced his more elaborate scheme of reconciliation between the Divine and the Geologic Records, in a "Review of Cuvier's Theory of the Earth;" and that scheme, perfectly adequate to bring the Mosaic narrative into harmony with what was known at the time of geologic history, has been very extensively received and adopted. It may, indeed, still be regarded as the most popular of the various existing schemes. It teaches, and teaches truly, that between the first act of creation, which evoked out of the previous nothing the _matter_ of the heavens and earth, and the first act of the first day's work recorded in Genesis, periods of vast duration may have intervened; but further, it insists that the days themselves were but natural days of twenty-four hours each; and that, ere they began, the earth, though mayhap in the previous period a fair residence of life, had become void and formless, and the sun, moon, and stars, though mayhap they had before given light, had been, at least in relation to our planet, temporarily extinguished. In short, while it teaches that the successive creations of the geologist may all have found ample room in the period preceding that creation to which man belongs, it teaches also that the record in Genesis bears reference to but the existing creation, and that there lay between it and the preceding ones a chaotic period of death and darkness. The scheme propounded by the late Dr. Pye Smith, and since adopted by several writers, differs from that of Chalmers in but one circumstance, though an important one. Dr. Smith held, with the great northern divine, that the Mosaic days were natural days; that they were preceded by a chaotic period; and that the work done in them related to but that last of the creations to which the human species belongs. Further, however, he held in addition, that the chaos of darkness and confusion out of which that creation was called was of but limited extent, and that outside its area, and during the period of its existence, many of our present lands and seas may have enjoyed the light of the sun, and been tenanted by animals and occupied by plants, the descendants of which still continue to exist. The treatise of Dr. Pye Smith was published exactly a quarter of a century posterior to the promulgation, through the press, of the argument of Dr. Chalmers; and this important addition,--elaborated by its author between the years 1837 and 1839,--seems to have been made to suit the more advanced state of geological science at the time. The scheme of reconciliation perfectly adequate in 1814 was found in 1839 to be no longer so; and this mainly through a peculiarity in the order in which geological fact has been evolved and accumulated in this country, and the great fossiliferous systems studied and wrought out; to which I must be permitted briefly to advert. William Smith, the "Father of English Geology," as he has been well termed (a humble engineer and mineral surveyor, possessed of but the ordinary education of men of his class and profession), was born upon the English Oolite,--that system which, among the five prevailing divisions of the great Secondary class of rocks, holds exactly the middle place. The Triassic system and the Lias lie beneath it; the Cretaceous system and the Weald rest above. Smith, while yet a child, had his attention attracted by the Oolitic fossils; and it was observed, that while his youthful contemporaries had their garnered stores of marbles purchased at the toy shop, he had collected, instead, a hoard of spherical fossil terebratulæ, which served the purposes of the game equally well. The interest which he took in organic remains, and the deposits in which they occur, influenced him in the choice of a profession; and, when supporting himself in honest independence as a skilful mineral surveyor and engineer, he travelled over many thousand miles of country, taking as his starting point the city of Bath, which stands near what is termed the Great Oolite: and from that centre he carefully explored the various Secondary formations above and below. He ascertained that these always occur in a certain determinate order; that each contains fossils peculiar to itself; and that they run diagonally across the kingdom in nearly parallel lines from north-east to south-west. And, devoting every hour which he could snatch from his professional labors to the work, in about a quarter of a century, or rather more, he completed his great stratigraphical map of England. But, though a truly Herculean achievement, regarded as that of a single man unindebted to public support, and uncheered by even any very general sympathy in his labors, it was found to be chiefly valuable in its tracings of the Secondary deposits, and strictly exact in only that Oolitic centre from which his labors began. It was remarked at an early period that he ought to have restricted his publication to the formations which lie between the Chalk and the Red Marl inclusive; or, in other words, to the great Secondary division. The Coal Measures had, however, been previously better known, from their economic importance, and the number of the workings opened among them, than the deposits of any other system; and ere the publication of the map of Smith, Cuvier and Brogniart had rendered famous all over the world the older Tertiary formations of the age of the London Clay. But both ends of the geological scale, comprising those ancient systems older than the Coal, and representative of periods in which, so far as is yet known, life, animal and vegetable, first began upon our planet, and those systems of comparatively modern date, representative of the periods which immediately preceded the human epoch, were equally unknown. The light fell strongly on only that middle portion of the series on which the labors of Smith had been mainly concentrated. The vast geologic bridge, which, like that in the exquisite allegory of Addison, strode across a "part of the great tide of eternity," "had a black cloud hanging at each end of it." And such was the state of geologic science when, in 1814, Dr. Chalmers framed his scheme of reconciliation. Since that time, however, a light not less strong than the one thrown by William Smith on the formations of the Lias and the Oolite has been cast on both the older and the newer fossiliferous systems. Two great gaps still remain to be filled up,--that which separates the Palæozoic from the Secondary division, and that which separates the Secondary from the Tertiary one. But they occur at neither end of the geological scale. Mainly through the labors of two distinguished geologists, who, finding the geologic school of their own country distracted by a fierce and fruitless controversy, attached themselves to the geologic school of England, and have since received the honor of knighthood in acknowledgment of their labors, both ends of the geologic scale have been completed. Sir Roderick Murchison addressed himself to the formations older than the Coal, more especially to the Upper and Lower Silurian systems, from the Ludlow rooks to the Llandeilo flags. The Old Red Sandstone too, a system which lies more immediately beneath the Coal, has also been explored, and its various deposits, with their peculiar organic remains, enumerated and described. And Sir Charles Lyell, setting himself to the other extremity of the scale, has wrought out the Tertiary formations, and separated them into the four great divisions which they are now recognized as forming. And of these, the very names indicate that certain proportions of their organisms still continue to exist. It is a great fact, now fully established in the course of geological discovery, that between the plants which in the present time cover the earth, and the animals which inhabit it, and the animals and plants of the later extinct creations, there occurred no break or blank, but that, on the contrary, many of the existing organisms were contemporary during the morning of their being, with many of the extinct ones during the evening of theirs. We know further, that not a few of the shells which now live on our coasts, and several of even the wild animals which continue to survive amid our tracts of hill and forest, were in existence many ages ere the human age began. Instead of dating their beginning only a single natural day, or at most two natural days, in advance of man, they must have preceded him by many thousands of years. In fine, in consequence of that comparatively recent extension of geologic fact in the direction of the later systems and formations, through which we are led to know that the present creation was not cut off abruptly from the preceding one, but that, on the contrary, it dovetailed into it at a thousand different points, we are led also to know, that any scheme of reconciliation which would separate between the recent and the extinct existences by a chaotic gulf of death and darkness, is a scheme which no longer meets the necessities of the case. Though perfectly adequate forty years ago, it has been greatly outgrown by the progress of geological discovery, and is, as I have said, adequate no longer; and it becomes a not unimportant matter to determine the special scheme that would bring into completest harmony the course of creation, as now ascertained by the geologist, and that brief but sublime narrative of its progress which forms a meet introduction in Holy Writ to the history of the human family. The first question to which we must address ourselves in any such inquiry is of course a very obvious one,--_What are the facts scientifically determined which now demand a new scheme of reconciliation?_ There runs around the shores of Great Britain and Ireland a flat terrace of unequal breadth, backed by an escarpment of varied height and character, which is known to geologists as the old coast-line. On this flat terrace most of the seaport towns of the empire are built. The subsoil which underlies its covering of vegetable mould consists usually of stratified sands and gravels, arranged after the same fashion as on the neighboring beach, and interspersed in the same manner with sea shells. The escarpment behind, when formed of materials of no great coherency, such as gravel or clay, exists as a sloping, grass-covered bank,--at one place running out into promontories that encroach upon the terrace beneath,--at another receding into picturesque, bay-like recesses; and where composed, as in many localities, of rock of an enduring quality, we find it worn, as if by the action of the surf,--in some parts relieved into insulated stacks, in others hollowed into deep caverns,--in short, presenting all the appearance of a precipitous coast-line, subjected to the action of the waves. Now, no geologist can or does doubt that this escarpment was at one time the coast-line of the island,--the line against which the waves broke at high water in some distant age, when either the sea stood from twenty to thirty feet higher along our shores than it does now, or the land sat from twenty to thirty feet lower. Nor can the geologist doubt, that along the flat terrace beneath, with its stratified beds of sand and gravel, and its accumulations of sea shells, the tides must have risen and fallen twice every day, as they now rise and fall along the beach that at present girdles our country. But, in reference to at least human history, the age of the old coast-line and terrace must be a very remote one. Though geologically recent, it lies far beyond the reach of any written record. It has been shown by Mr. Smith of Jordanhill, one of our highest authorities on the subject, that the wall of Antoninus, erected by the Romans as a protection against the Northern Caledonians, was made to terminate at the Firths of Forth and Clyde, with relation, not to the level of the old coast-line, but to that of the existing one. And so we must infer that, ere the year A.D. 140 (the year during which, according to our antiquaries, the greater part of the wall was erected) the old coast-line had attained to its present elevation over the sea. Further, however, we know from the history of Diodorus the Sicilian, that at a period earlier by at least two hundred years, St. Michael's Mount, in Cornwall, was connected with the mainland at low water, just as it is now, by a flat isthmus, across which, upon the falling of the tide, the ancient Cornish miners used to carry over their tin in carts. Had the relative levels of sea and land been those of the old coast-line at the time, St. Michael's Mount, instead of being accessible at low ebb would have been separated from the shore by a strait from three to five fathoms in depth. It would not have been then as now, as described in the verse of Carew,-- "Both land and island twice a day." But even the incidental notice of Diodorus Siculus represents very inadequately the antiquity of the existing coast-line. Some of its caves, hollowed in hard rock in the line of faults and shifts by the attrition of the surf, are more than a hundred feet in depth; and it must have required many centuries to excavate tough trap or rigid gneiss to a depth so considerable, by a process so slow. And yet, however long the sea may have stood against the present coast-line, it must have stood for a considerably longer period against the ancient one. The latter presents generally marks of greater attrition than the modern line, and its wave-hollowed caves are of a depth considerably more profound. In determining, on an extensive tract of coast, the average profundity of both classes of caverns from a considerable number of each, I ascertained that the proportional average depth of the modern to the ancient is as two to three. For every two centuries, then, during which the waves have been scooping out the caves of the present coast-line, they must have been engaged for three centuries in scooping out those of the old one. But we know _historically_, that for at least twenty centuries the sea has been toiling in these modern caves; and who shall dare affirm that it has not been toiling in them for at least ten centuries more? But if the sea has stood for but even two thousand six hundred years against the present coast-line (and no geologist would dare fix his estimate lower), then must it have stood against the old line, ere it could have excavated caves one third deeper, three thousand nine hundred years. And both periods united (six thousand five hundred years) more than exhaust the Hebrew chronology. Yet what a mere beginning of geologic history does not the epoch of the old coast-line form! It is but a mere starting point from the recent period. Not a single shell seems to have become extinct during the last six thousand five hundred years! The shells which lie embedded in the subsoils beneath the old coast-line are exactly those which still live in our seas. [Illustration: Fig. 87. ASTARTE ARCTICA.] [Illustration: Fig. 88. TELLINA PROXIMA.] Above this ancient line of coast we find, at various heights, beds of shells of vastly older date than those of the low-lying terrace, and many of which are no longer to be found living around our shores. I spent some time last autumn in exploring one of these beds, once a sea bottom, but now raised two hundred and thirty feet over the sea, in which there occurred great numbers of shells now not British, though found in many parts of Britain at heights varying from two hundred to nearly fourteen hundred feet over the existing sea level. But though no longer British shells, they are shells that still continue to live in high northern latitudes, as on the shores of Iceland and Spitzbergen; and the abundance in which they were developed on the submerged plains and hill-sides of what are now England and Scotland, during what is termed the Pleistocene period, shows of itself what a very protracted period that was. The prevailing tellina of the bed which I last explored,--a bed which occurs in some places six miles inland, in others elevated on the top of dizzy crags,--is a sub-arctic shell (_Tellina proxima_), of which only dead valves are now to be detected on our coasts, but which may be found living at the North Cape and in Greenland. The prevailing astarte, its contemporary, was _Astarte arctica_, now so rare as a British species, that many of our most sedulous collectors have never seen a native specimen, but which is comparatively common on the northern shores of Iceland, and on the eastern coasts of Norway, within the arctic circle. In this elevated Scottish bed of the Pleistocene period I laid these boreal shells open to the light by hundreds, on the spot evidently where the individuals had lived and died. Under the severe climatal conditions to which (probably from some change in the direction of the gulf stream) what is now Northern Europe had been brought, this tellina and astarte had increased and multiplied until they became prevailing shells of the British area; and this increase must have been the slow work of ages, during which the plains, and not a few of the table lands, of the country, were submerged in a sub-arctic sea, and Great Britain existed as but a scattered archipelago of wintry islands. But in a still earlier period, of which there exists unequivocal evidence in the buried forests of Happisburgh and Cromer, the country had not only its head above water, as now, but seems to have possessed oven more than its present breadth of surface. During this ancient time,--more remote by many centuries than not only the times of the old coast-line, but than even those of the partial submergence of the island,--that northern mammoth lived in great abundance, of which the remains have been found by hundreds in England alone, together with the northern hippopotamus, and at least two northern species of rhinoceros. And though they have all ceased to exist, with their wild associates in the forests and jungles of the Pleistocene, the cave-hyæna, the cave-tiger, and the cave-bear, we know that the descendants of some of their feebler contemporaries, such as the badger, the fox, the wild cat, and the red deer, still live amid our hills and brakes. The trees, too, under which they roamed, and whose remains we find buried in the same deposits as theirs, were of species that still hold their place as aboriginal trees of the country, or of at least the more northerly provinces of the continent. The common Scotch fir, the common birch, and a continental species of conifer of the far north, the Norwegian spruce (_Abies excelsa_), have been found underlying the Pleistocene drift, and rooted in the mammiferous crag; and for many ages must the old extinct elephant have roamed amid these familiar trees. From one limited tract of sea bottom on the Norfolk coast the fishermen engaged in dredging oysters brought ashore, in the course of thirteen years (from 1820 to 1833), no fewer than two thousand elephants' grinders, besides great tusks and numerous portions of skeletons. It was calculated that these remains could not have belonged to fewer than five hundred individual mammoths of English growth; and, various in their states of keeping, and belonging to animals of which only a few at a time could have found sufficient food in a limited tract of country, the inference seems inevitable that they must have belonged, not to one or two, but to many succeeding generations. The further fact, that remains of this ancient elephant (_Elephas primigenius_) occur all round the globe in a broad belt, extending from the fortieth to near the seventieth degree of north latitude, leads to the same conclusion. It must have required many ages ere an animal that breeds so slowly as the elephant could have extended itself over an area so vast. [Illustration: Fig. 89. NORWEGIAN SPRUCE. (Abies excelsa.)] Many of the contemporaries of this northern mammoth, especially of its molluscan contemporaries, continue, as I have said, to live in their descendants. Of even a still more ancient period, represented by the Red Crag, seventy out of every hundred species of shells still exist; and of an older period still, represented by the Coraline Crag, there survive sixty out of every hundred. In the Red Crag, for instance, we find the first known ancestors of our common edible periwinkle and common edible mussel; and in the Coraline Crag, the first known ancestors of the common horse-mussel, the common whelk, the common oyster, and the great pecten. There then occurs a break in the geologic deposits of Britain, which, however, in other parts of Europe we find so filled up as to render it evident that no corresponding break took place in the chain of existence; but that, on the contrary, from the present time up to the times represented by the earliest Eocene formations of the Tertiary division, day has succeeded day, and season has followed season, and that no chasm or hiatus--no age of general chaos, darkness, and death--has occurred, to break the line of succession, or check the course of life. All the evidence runs counter to the supposition that immediately before the appearance of man upon earth, there existed a chaotic period which separated the previous from the present creation. Up till the commencement of the Eocene ages, if even then, there was no such chaotic period, in at least what is now Britain and the European continent: the persistency from a high antiquity of some of the existing races, of not only plants and shells, but of even some of the mammiferous animals, such as the badger, the goat, and the wild cat, prove there was not; and any scheme of reconciliation which takes such a period for granted must be deemed as unsuited to the present state of geologic knowledge, as any scheme would have been forty years ago which took it for granted that the writings of Moses _do_ "fix the antiquity of the globe." The scheme of reconciliation adopted by the late Dr. Pye Smith, though, save in one particular, identical, as I have said, with that of Dr. Chalmers, is made, in virtue of its single point of difference, to steer clear of the difficulty. Both schemes exhibit the creation recorded in Genesis as an event which took place about six thousand years ago; both describe it as begun and completed in six natural days; and both represent it as cut off from a previously existing creation by a chaotic period of death and darkness. But while, according to the scheme of Chalmers, both the Biblical creation and the previous period of death are represented as coextensive with the globe, they are represented, according to that of Dr. Smith, as limited and local. They may have extended, it is said, over only a few provinces of Central Asia, in which, when all was life and light in other parts of the globe, there reigned for a time only death and darkness amid the welterings of a chaotic sea; which, at the Divine command, was penetrated by light, and occupied by dry land, and ultimately, ere the end of the creative week, became a centre in which certain plants and animals, and finally man himself, were created. And this scheme, by leaving to the geologist in this country and elsewhere, save mayhap in some unknown Asiatic district, his unbroken series, certainly does not conflict with the facts educed by geologic discovery. It virtually removes Scripture altogether out of the field. I must confess, however, that on this, and on some other accounts, it has failed to satisfy me. I have stumbled, too, at the conception of a merely local and limited chaos, in which the darkness would be so complete, that when first penetrated by the light, that penetration could be described as actually a _making_ or creating of light; and that, while life obtained all around its precincts, could yet be thoroughly void of life, A local darkness so profound as to admit no ray of light seems to have fallen for a time on Egypt, as one of the ten plagues; but the event was evidently miraculous; and no student of natural science is entitled to have recourse, in order to extricate himself out of a difficulty, to supposititious, unrecorded miracle. Creation cannot take place without miracle; but it would be a strange reversal of all our previous conclusions on the subject, should we have to hold that the dead, dark, blank out of which creation arose was miraculous also. And if, rejecting miracle, we cast ourselves on the purely natural, we find that the local darknesses dependent on known causes, of which we have any record in history, were always either very imperfect, like the darkness of your London fogs, or very temporary, like the darkness described by Pliny as occasioned by a cloud of volcanic ashes; and so, altogether inadequate to meet the demands of a hypothesis such as that of Dr. Smith. And yet further, I am disposed, I must add, to look for a broader and more general meaning in that grand description of the creation of all things with which the Divine record so appropriately opens, than I could recognize it as forming, were I assured it referred to but one of many existing creations,--a creation restricted to mayhap a few hundred square miles of country, and to mayhap a few scores of animals and plants. What, then, is the scheme of reconciliation which I would venture to propound? Let me first remark, in reply, that I come before you this evening, not as a philologist, but simply as a student of geological fact, who, believing his Bible, believes also, that though theologians have at various times striven hard to pledge it to false science, geographical, astronomical, and geological, it has been pledged by its Divine Author to no falsehood whatever. I occupy exactly the position now, with respect to geology, that the mere Christian geographer would have occupied with respect to geography in the days of those doctors of Salamanca who deemed it unscriptural to hold with Columbus that the world is round,--not flat; or exactly the position which the mere Christian astronomer would have occupied with respect to astronomy in the days of that Francis Turrettine who deemed it unscriptural to hold with Newton and Galileo, that it is the earth which moves in the heavens, and the sun which stands still. The mere geographer or astronomer might have been wholly unable to discuss with Turrettine or the doctors the niceties of Chaldaic punctuation, or the various meanings of the Hebrew verbs. But this much, notwithstanding, he would be perfectly qualified to say:--However great your skill as linguists, your reading of what you term the scriptural geography or scriptural astronomy must of necessity be a false reading, seeing that it commits Scripture to what, in my character as a geographer or astronomer, I know to be a monstrously false geography or astronomy. Premising, then, that I make no pretensions to even the slightest skill in philology, I remark further, that it has been held by accomplished philologists, that the days of the Mosaic creation may be regarded, without doing violence to the genius of the Hebrew language, as successive periods of great extent. And certainly, in looking at my English Bible, I find that the portion of time spoken of in the first chapter of Genesis as _six_ days, is spoken of in the second chapter as _one_ day. True, there are other philologers, such as the late Professor Moses Stuart, who take a different view; but then I find this same Professor Stuart striving hard to make the phraseology of Moses "fix the antiquity of the globe;" and so, as a mere geologist, I reject his philology, on exactly the same principle on which the mere geographer would reject, and be justified in rejecting, the philology of the doctors of Salamanca, or on which the mere astronomer would reject, and be justified in rejecting, the philology of Turrettine and the old Franciscans. I would, in any such case, at once, and without hesitation, cut the philological knot, by determining that that philology cannot be sound which would commit the Scriptures to a science that cannot be true. Waiving, however, the question as a philological one, and simply holding with Cuvier, Parkinson, and Silliman, that each of the _six_ days of the Mosaic narrative in the first chapter were what is assuredly meant by the _day_ referred to in the second,--not natural days, but lengthened periods,--I find myself called on, as a geologist, to account for but three of the six. Of the period during which light was created,--of the period during which a firmament was made to separate the waters from the waters,--or of the period during which the two great lights of the earth, with the other heavenly bodies, became visible from the earth's surface,--we need expect to find no record in the rocks. Let me, however, pause for a moment, to remark the peculiar character of the language in which we are first introduced in the Mosaic narrative to the heavenly bodies,--sun, moon, and stars. The moon, though absolutely one of the smallest lights of our system, is described as secondary and subordinate to only its greatest light, the sun. It is the apparent, then, not the actual, which we find in the passage,--what _seemed_ to be, not what _was_; and as it was merely what appeared to be greatest that was described as greatest, on what grounds are we to hold that it may not also have been what _appeared_ at the time to be made that has been described as made? The sun, moon, and stars may have been created long before, though it was not until this fourth period of creation that they became visible from the earth's surface. The geologist, in his attempts to collate the Divine with the geologic record, has, I repeat, only three of the six periods of creation to account for,--the period of plants, the period of great sea monsters and creeping things, and the period of cattle and beasts of the earth. He is called on to question his systems and formations regarding the remains of these three great periods, and of these only. And the question once fairly stated, what, I ask, is the reply? All geologists agree in holding that the vast geological scale naturally divides into _three_ great parts. There are many lesser divisions,--divisions into systems, formations, deposits, beds, strata; but the master divisions, in each of which we find a type of life so unlike that of the others, that even the unpractised eye can detect the difference, are simply three,--the Palæozoic, or oldest fossiliferous division; the Secondary, or middle fossiliferous division; and the Tertiary, or latest fossiliferous division. In the first, or Palæozoic division, we find corals, crustaceans, molluscs, fishes, and, in its later formations, a few reptiles. But none of these classes of organisms give its leading character to the Palæozoic; they do not constitute its prominent feature, or render it more remarkable as a scene of life than any of the divisions which followed. That which chiefly distinguished the Palæozoic from the Secondary and Tertiary periods was its gorgeous flora. It was emphatically the period of plants,--"of herbs yielding seed after their kind." In no other age did the world ever witness such a flora: the youth of the earth was peculiarly a green and umbrageous youth,--a youth of dusk and tangled forests, of huge pines and stately araucarians, of the reed-like calamite, the tall tree-fern, the sculptured sigillaria, and the hirsute lepidodendron. Wherever dry land, or shallow lake, or running stream appeared, from where Melville Island now spreads out its ice wastes under the star of the pole, to where the arid plains of Australia lie solitary beneath the bright cross of the south, a rank and luxuriant herbage cumbered every footbreadth of the dank and steaming soil; and even to distant planets our earth must have shone through the enveloping cloud with a green and delicate ray. Of this extraordinary age of plants we have our cheerful remembrancers and witnesses in the flames that roar in our chimneys when we pile up the winter fire,--in the brilliant gas that now casts its light on this great assemblage, and that lightens up the streets and lanes of this vast city,--in the glowing furnaces that smelt our metals, and give moving power to our ponderous engines,--in the long dusky trains that, with shriek and snort, speed dart-like athwart our landscapes,--and in the great cloud-enveloped vessels that darken the lower reaches of your noble river, and rush in foam over ocean and sea. The geologic evidence is so complete as to be patent to all, that the first great period of organized being was, as described in the Mosaic record, peculiarly a period of herbs and trees, "yielding seed after their kind." The middle great period of the geologist--that of the Secondary division--possessed, like the earlier one, its herbs and plants, but they were of a greatly less luxuriant and conspicuous character than their predecessors, and no longer formed the prominent trait or feature of the creation to which they belonged. The period had also its corals, its crustaceans, its molluscs, its fishes, and in some one or two exceptional instances its dwarf mammals. But the grand existences of the age,--the existences in which it excelled every other creation, earlier or later, were its huge creeping things,--its enormous monsters of the deep,--and, as shown by the impressions of their footprints stamped upon the rocks, its gigantic birds. It was peculiarly the age of egg-bearing animals, winged and wingless. Its wonderful _whales_, not, however, as now, of the mammalian, but of the reptilian class,--ichthyosaurs, plesiosaurs, and cetiosaurs,--must have tempested the deep; its creeping lizards and crocodiles, such as the teliosaurus, megalosaurus, and iguanodon,--creatures some of which more than rivalled the existing elephant in height, and greatly more than rivalled him in bulk,--must have crowded the plains or haunted by myriads the rivers of the period; and we know that the footprints of at least one of its many birds are fully twice the size of those made by the horse or camel. We are thus prepared to demonstrate, that the second period of the geologist was peculiarly and characteristically a period of whale-like reptiles of the sea, of enormous creeping reptiles of the land, and of numerous birds, some of them of gigantic size; and, in meet accordance with the fact, we find that the second Mosaic period with which the geologist is called on to deal was a period in which God created the fowl that flieth above the earth, with moving [or creeping] creatures, both in the waters and on the land, and what our translation renders great whales, but that I find rendered, in the margin, great sea monsters. The Tertiary period had also its prominent class of existences. Its flora seems to have been no more conspicuous than that of the present time; its reptiles occupy a very subordinate place; but its beasts of the field were by far the most wonderfully developed, both in size and numbers, that ever appeared upon earth. Its mammoths and its mastodons, its rhinoceri and its hippopotami, its enormous dinotherium and colossal megatherium, greatly more than equalled in bulk the largest mammals of the present time, and vastly exceeded them in number. The remains of one of its elephants (_Elephas primigenius_) are still so abundant amid the frozen wastes of Siberia, that what have been not inappropriately termed "ivory quarries" have been wrought among their bones for more than a hundred years. Even in our own country, of which, as I have already shown, this elephant was for long ages a native, so abundant are the skeletons and tusks, that there is scarcely a local museum in the kingdom that has not its specimens, dug out of the Pleistocene deposits of the neighborhood. And with this ancient elephant there were meetly associated in Britain, as on the northern continents generally all around the globe, many other mammals of corresponding magnitude. "Grand indeed," says an English naturalist, "was the fauna of the British islands in those early days. Tigers as large again as the biggest Asiatic species lurked in the ancient thickets; elephants of nearly twice the bulk of the largest individuals that now exist in Africa or Ceylon roamed in herds; at least two species of rhinoceros forced their way through the primeval forest; and the lakes and rivers were tenanted by hippopotami as bulky, and with as great tusks, as those of Africa." The massive cave-bear and large cave-hyæna belonged to the same formidable group, with at least two species of great oxen (_Bos longifrons_ and _Bos primigenius_), with a horse of smaller size, and an elk (_Megaceros Hibernicus_) that stood ten feet four inches in height. Truly this Tertiary age--this third and last of the great geologic periods--was peculiarly the age of great "beasts of the earth after their kind, and of cattle after their kind." Permit me at this stage, in addressing myself to a London audience, to refer to what has been well termed one of the great _sights_ of London. An illustration drawn from what must be familiar to you all may impart to your conceptions, respecting the facts on which I build, a degree of tangibility which otherwise they could not possess. [Illustration: Fig. 90. LEPIDODENDRON STERNBERGII.] One of perhaps the most deeply interesting departments of your great British Museum--the wonder of the world--is that noble gallery, consisting of a suite of rooms, opening in line, the one beyond the other, which forms its rich storehouse of organic remains. You must of coarse remember the order in which the organisms of that gallery are ranged. The visitor is first ushered into a spacious room devoted to fossil plants, chiefly of the Coal Measures. And if these organisms are in any degree less imposing in their aspect than those of the apartments which follow in the series, it is only because that, from the exceeding greatness of the Coal Measure plants, they can be exhibited in but bits and fragments. Within less than an hour's walk of the Scottish capital there are single trees of this ancient period deeply embedded in the sandstone strata, which, though existing as mere mutilated portions of their former selves, would yet fail to find accommodation in that great apartment. One of those fossil trees,--a noble araucarian,--which occurs in what is known as the Granton quarry, is a mere fragment, for it wants both root and top, and yet what remains is sixty-one feet in length by six feet in diameter; and beside it there lies a smaller araucarian, also mutilated, for it wants top and branches, and _it_ measures seventy feet in length by four feet in diameter. I saw lately, in a quarry of the Coal Measures about two miles from my dwelling-house, near Edinburgh, the stem of a plant (_Lepidodendron Sternbergii_), allied to the dwarfish club mosses of our moors, considerably thicker than the body of a man, and which, reckoning on the ordinary proportions of the plant, must have been at least seventy feet in height. And of a kind of aquatic reed (calamites), that more resembles the diminutive mare's tail of our marshes than aught else that now lives, remains have been found in abundance in the same coal field, more than a foot in diameter by thirty feet in length. Imposing, then, as are the vegetable remains of this portion of the National Museum, they would be greatly more imposing still did they more adequately represent the gigantic flora of the remote age to which they belong. [Illustration: Fig. 91. CALAMITES CANNÆFORMIS.] Passing onwards in the gallery from the great plants of the Palæozoic division to the animals of the Secondary one, the attention is at once arrested by the monstrous forms on the wall. Shapes that more than rival in strangeness the great dragons, and griffins, and "laithly worms," of mediæval legend, or, according to Milton, the "gorgons, hydras, and chimeras dire," of classical fable, frown on the passing visitor; and, though wrapped up in their dead and stony sleep of ages, seem not only the most strange, but also the most terrible things on which his eye ever rested. Enormous jaws, bristling with pointed teeth, gape horrid in the stone, under staring eye-sockets a full foot in diameter. Necks that half equal in length the entire body of the boa-constrictor stretch out from bodies mounted on fins like those of a fish, and furnished with tails somewhat resembling those of the mammals. Here we see a winged dragon, that, armed with sharp teeth and strong claws, had careered through the air on leathern wings like those of a bat; there an enormous crocodilian whale, that, mounted on many-jointed paddles, had traversed, in quest of prey, the green depths of the sea; yonder a herbivorous lizard, with a horn like that of the rhinoceros projecting from its snout, and that, when it browsed amid the dank meadows of the Wealden, must have stood about twelve feet high. All is enormous, monstrous, vast, amid the creeping and flying things and the great sea monsters of this division of the gallery. [Illustration: Fig. 92. MEGATHERIUM CUVIERI.] We pass on into the third and lower division, and an entirely different class of existences now catch the eye. The huge mastodon, with his enormous length of body, and his tusks projecting from both upper and under jaw, stands erect in the middle of the floor,--a giant skeleton. We see beside him the great bones of the megatherium,--thigh bones eleven inches in diameter, and claw-armed toes more than two feet in length. There, too, ranged species beyond species, are the extinct elephants; and there the ponderous skull of the dinotherium, with the bent tusks in its lower jaw, that give to it the appearance of a great pickaxe, and that must have dug deeply of old amid the liliaceous roots and bulbs of the Tertiary lakes and rivers. There also are the massive heads and spreading horn-cores of the _Bos primigenius_, and the large bones and broad plank-like horns of the great Irish elk. And there too, in the same apartment, but leaning against its further wall,--last, as most recent, of all the objects of wonder in that great gallery,--is the famous human skeleton of Guadaloupe, standing out in bold relief from its slab of gray limestone. It occurs in the series, just as the series closes, a little beyond the mastodon and the mammoths; and, in its strange character as a fossil man, attracts the attention scarce less powerfully than the great Palæozoic plants, the great Secondary reptiles, or the great Tertiary mammals. [Illustration: Fig. 93. SKULL OF DINOTHERIUM GIGANTEUM. (_Miocene._)] I last passed through this wondrous gallery at the time when the attraction of the Great Exhibition had filled London with curious visitors from all parts of the empire; and a group of intelligent mechanics, fresh from some manufacturing town of the midland counties, were sauntering on through its chambers immediately before me. They stood amazed beneath the dragons of the Oolite and Lias; and, with more than the admiration and wonder of the disciples of old when contemplating the huge stones of the Temple, they turned to say, in almost the old words, "Lo! master, what manner of great beasts are these?" "These are," I replied, "the sea monsters and creeping things of the second great period of organic existence." The reply seemed satisfactory, and we passed on together to the terminal apartments of the range appropriated to the Tertiary organisms. And there, before the enormous mammals, the mechanics again stood in wonder, and turned to inquire. Anticipating the query, I said, "And these are the huge beasts of the earth, and the cattle of the third great period of organic existence; and yonder, in the same apartment, you see, but at its further end, is the famous fossil man of Guadaloupe, locked up by the petrifactive agencies in a slab of limestone." The mechanics again seemed satisfied. And, of course, had I encountered them in the first chamber of the suite, and had they questioned me respecting the organisms with which _it_ is occupied, I would have told them that they were the remains of the herbs and trees of the _first_ great period of organic existence. But in the chamber of the mammals we parted, and I saw them no more. There could not be a simpler incident. And yet, rightly apprehended, it reads its lesson. You have all visited the scene of it, and must all have been struck by the three salient points, if I may so speak, by which that noble gallery lays strongest hold of the memory, and most powerfully impresses the imagination,--by its gigantic plants of the first period (imperfectly as these are represented in the collection), by its strange misproportioned sea monsters and creeping things of the second, and by its huge mammals of the third. Amid many thousand various objects, and a perplexing multiplicity of detail, which it would require the patient study of years even partially to classify and know, these are the great prominent features of the gallery, that involuntarily, on the part of the visitor, force themselves on his attention. They at once pressed themselves on the attention of the intelligent though unscientific mechanics, and, I doubt not, still dwell vividly in their recollections; and I now ask you, when you again visit the national museum, and verify the fact of the great prominence of these classes of objects, to bear in mind, that the gallery in which they occur represents, both in the order and character of its contents, the course of creation. I ask you to remember that, had there been human eyes on earth during the Palæozoic, Secondary, and Tertiary periods, they would have been filled in succession by the great plants, the great reptiles, and the great mammals, just as those of the mechanics were filled by them in the museum. As the sun and moon, when they first became visible in the heavens, would have seemed to human eyes--had there been human eyes to see--not only the greatest of the celestial lights, but peculiarly the prominent objects of the epoch in which they appeared, so would these plants, reptiles, and mammals, have seemed in succession the prominent objects of the several epochs in which _they_ appeared. And, asking the geologist to say whether my replies to the mechanics were not, with all their simplicity, true to geological fact, and the theologian to say whether the statements which they embodied were not, with all their geology, true to the scriptural narrative, I ask further, whether (of course, making due allowance for the laxity of the terms botanic and zoological of a primitive language unadapted to the niceties of botanic or zoologic science) the Mosaic account of creation could be rendered more essentially true, than we actually find it, to the history of creation geologically ascertained. If, taking the Mosaic days as equivalent to lengthened periods, we hold that, in giving their brief history, the inspired writer seized on but those salient points that, like the two great lights of the day and night, would have arrested most powerfully, during these periods, a human eye, we shall find the harmony of the two records complete. In your visit to the museum, I would yet further ask you to mark the place of the human skeleton in the great gallery. It stands--at least it stood only a few years ago--in the same apartment with the huge mammifers. And it is surely worthy of remark, that while in both the sacred and geologic records a strongly defined line separates between the period of plants and the succeeding periods of reptiles, and again between the period of reptiles and the succeeding period of mammals, no line in either record separates between this period of mammals and the human period. Man came into being as the lastborn of creation, just ere the close of that sixth day--the third and terminal period of organic creation--to which the great mammals belong. Let me yet further remark, that in each of these three great periods we find, with respect to the classes of existences, vegetable or animal, by which they were most prominently characterized, certain well marked culminating points together, if I may so express myself,--twilight periods of morning dawn and evening decline. The plants of the earlier and terminal systems of the Palæozoic division are few and small: it was only during the protracted _eons_ of the Carboniferous period that they received their amazing development, unequalled in any previous or succeeding time.[16] In like manner, in the earlier or Triassic deposits of the Secondary division, the reptilian remains are comparatively inconsiderable; and they are almost equally so in its Cretaceous or later deposits. It was during those middle ages of the division, represented by its Liassic, Oolitic, and Wealden formations, that the class existed in that abundance which rendered it so peculiarly, above every other age, an age of creeping things and great sea monsters. And so also, in the Tertiary, regarded as but an early portion of the human division, there was a period of increase and diminution,--a morning and evening of mammalian life. The mammals of its early Eocene ages were comparatively small in bulk and low in standing; in its concluding ages, too, immediately ere the appearance of man, or just as he had appeared, they exhibited, both in size and number, a reduced and less imposing aspect. It was chiefly in its middle and latter, or Miocene, Pliocene, and Pleistocene ages, that the myriads of its huger giants,--its dinotheria, mastodons, and mammoths,--cumbered the soil. I, of course, restrict my remarks to the three periods of organic life, and have not inquired whether aught analogous to these mornings and evenings of increase and diminution need be sought after in any of the others. Such are a few of the geological facts which lead me to believe that the _days_ of the Mosaic account were great periods, not natural days; and be it remembered, that between the scheme of lengthened periods and the scheme of a merely local chaos, which existed no one knows how, and of a merely local creation, which had its scene no one knows where, geological science leaves us now no choice whatever. It has been urged, however, that this scheme of periods is irreconcileable with that Divine "reason" for the institution of the Sabbath which he who appointed the day of old has, in his goodness, vouchsafed to man. I have failed to see any force in the objection. God the Creator, who wrought during six periods, rested during the seventh period; and as we have no evidence whatever that he recommenced his work of creation,--as, on the contrary, man seems to be the last formed of creatures,--God may be resting still. The presumption is strong that his Sabbath is an extended period, not a natural day, and that the work of Redemption is his Sabbath day's work. And so I cannot see that it in the least interferes with the integrity of the reason rendered to read it as follows:--Work during six periods, and rest on the seventh; for in six periods the Lord created the heavens and the earth, and on the seventh period _He_ rested. The Divine periods may have been very great,--the human periods very small; just as a vast continent or the huge earth itself is very great, and a map or geographical globe very small. But if in the map or globe the proportions be faithfully maintained, and the scale, though a minute one, be true in all its parts and applications, we pronounce the map or globe, notwithstanding the smallness of its size, a faithful copy. Were man's Sabbaths to be kept as enjoined, and in the Divine proportions, it would scarcely interfere with the logic of the "reason annexed to the fourth commandment," though in this matter, as in all others in which man can be an imitator of God, the imitation should be a miniature one. The work of Redemption may, I repeat, be the work of God's Sabbath day. What, I ask, viewed as a whole, is the prominent characteristic of geologic history, or of that corresponding history of creation which forms the grandly fashioned vestibule of the sacred volume? Of both alike the leading characteristic is progress. In both alike do we find an upward progress from dead matter to the humbler forms of vitality, and from thence to the higher. And after great cattle and beasts of the earth had, in due order, succeeded inanimate plants, sea monsters, and moving creatures that had life, the moral agent, man, enters upon the scene. Previous to his appearance on earth, each succeeding elevation in the long upward march had been a result of creation. The creative fiat went forth, and dead matter came into existence. The creative fiat went forth, and plants, with the lower animal forms, came into existence. The creative fiat went forth, and the oviparous animals,--birds and reptiles,--came into existence. The creative fiat went forth, and the mammiferous animals,--cattle and beasts of the earth,--came into existence. And, finally, last in the series, the creative fiat went forth, and responsible, immortal man, came into existence. But has the course of progress come, in consequence, to a close? No. God's work of elevating, raising, heightening,--of making the high in due progression succeed the low,--still goes on. But man's responsibility, his immortality, his God-implanted instincts respecting an eternal future, forbid that that work of elevation and progress should be, as in all the other instances, a work of creation. To create would be to supersede. God's work of elevation _now_ is the work of fitting and preparing peccable, imperfect man for a perfect, impeccable, future state. God's seventh day's work is the work of Redemption. And, read in this light, his reason vouchsafed to man for the institution of the Sabbath is found to yield a meaning of peculiar breadth and emphasis. God, it seems to say, rests on _his_ Sabbath from his creative labors, in order that by his Sabbath day's work he may save and elevate you. Rest ye also on your Sabbaths, that through your co-operation with him in this great work ye may be elevated and saved. Made originally in the image of God, let God be your pattern and example. Engaged in your material and temporal employments, labor in the proportions in which he labored; but, in order that you may enjoy an eternal future with him, rest also in the proportions in which he rests. One other remark ere I conclude. In the history of the earth which we inhabit, molluscs, fishes, reptiles, mammals, had each in succession their periods of vast duration; and then the human period began,--the period of a fellow worker with God, created in God's own image. What is to be the next advance? Is there to be merely a repetition of the past?--an introduction a second time of man made in the image of God? No. The geologist, in those tables of stone which form his records, finds no example of dynasties once passed away again returning. There has been no repetition of the dynasty of the fish, of the reptile, of the mammal. The dynasty of the future is to have glorified man for its inhabitant; but it is to be the dynasty--"the _kingdom_"--not of glorified man made in the image of God, but of God himself in the form of man. In the doctrine of the two conjoined natures, human and Divine, and in the further doctrine that the terminal dynasty is to be peculiarly the dynasty of HIM in whom the natures are united, we find that required progression beyond which progress cannot go. We find the point of elevation never to be exceeded meetly coincident with the final period never to be terminated,--the infinite in height harmoniously associated with the eternal in duration. Creation and the Creator meet at one point, and in one person. The long ascending line from dead matter to man has been a progress Godwards,--not an asymptotical progress, but destined from the beginning to furnish a point of union; and occupying that point as true God and true man,--as Creator and created,--we recognize the adorable Monarch of all the future! LECTURE FOURTH. THE MOSAIC VISION OF CREATION. The history of creation is introduced into the "Paradise Lost" as a piece of narrative, and forms one of the two great episodes of the poem. Milton represents the common father of the race as "led on" by a desire to know "What within Eden or without was done Before his memory;" and straightway Raphael, "the affable archangel," in compliance with the wish, enters into a description of the six days' work of the Divine Creator,--a description in which, as Addison well remarks, "the whole energy of our tongue is employed, and the several great scenes of creation rise up to view, one after another, in such a manner, that the reader seems present at this wonderful work, and to assist among the choirs of angels who are spectators of it." In the other great episode of the poem,--that in which the more prominent changes which were to happen in after time upon the earth are made to pass before Adam, he is represented as carried by Michael to the top of a great mountain, lofty as that on which in a long posterior age the Tempter placed our Saviour, and where the coming events are described as rising up in vision before him. In the earlier episode, as in those of the Odyssey and Æneid, in which heroes relate in the courts of princes the story of their adventures, there is but narrative and description; in the later, a series of magnificent pictures, that form and then dissolve before the spectator, and comprise, in their vivid tints and pregnant outlines, the future history of a world. And one of these two episodes,--that which relates to the creation of all things,--must have as certainly had a place in human history as in the master epic of England. Man would have forever remained ignorant of many of those events related in the opening chapters of Scripture, which took place ere there was a human eye to witness, or a human memory to record, had he not been permitted, like Adam of old, to hold intercourse with the intelligences that had preceded him in creation, or with the great Creator himself, the Author of them all; and the question has been asked of late, both in our own country and on the Continent, What was the form and nature of the revelation by which the pre-Adamic history of the earth and heavens was originally conveyed to man? Was it conveyed, like the sublime story of Raphael, as a piece of narrative, dictated, mayhap, to the inspired penman, or miraculously borne in upon his mind? Or was it conveyed by a succession of sublime visions like that which Michael is represented as calling up before Adam, when, purging his "visual nerves with euphrasy and rue," he enabled him to see, in a series of scenes, the history of his offspring from the crime of Cain down to the destruction of the Old World by a flood? The passages in which the history of creation is recorded give no intimation whatever of their own history; and so we are left to balance the probabilities regarding the mode and form in which they were originally revealed, and to found our ultimate conclusions respecting them on evidence, not direct, but circumstantial. The Continental writers on this curious subject may be regarded as not inadequately represented by Dr. J.H. Kurtz, Professor of Theology at Dorpat,--one of the many ingenious biblical scholars of modern Germany. We find him stating the question, in his _Bibel und Astronomie_ (second edition, 1849), with great precision and clearness, but in a manner, so far at least as the form of his thinking is concerned, strikingly characteristic of what may be termed the theological fashion of his country in the present day. "The source of all human history," he says, "is _eye-witness_, be it that of the reporter, or of another whose account has been handed down. Only what man has himself seen or experienced can be the subject of man's historical compositions. So that history, so far as man can write it, can begin with but the point at which he has entered into conscious existence, and end with the moment that constitutes the present time. Beyond these points, however, lies a great province of historic development, existing on the one side as the _Past_, on the other side as the _Future_. For when man begins to be an observer or actor of history, he himself, and the whole circumstantials of his condition, have already come historically into being. Nor does the flow of development stop with what is his present. Millions of influences are spinning the thread still on; but no one can tell what the compound result of all their energies is to be. Both these sorts of history, then, lie beyond the region of man's knowledge, which is shut up in space and time, and can only call the present its own. It is God alone who, standing beyond and above space and time, sees backwards and forwards both the development which preceded the first _present_ of men, and that which will succeed this our latest _present_. Whatever the difference of the two kinds of history may be, they hold the same position in relation both to the principle of the human ignorance and the principle of the human knowledge. The principle of the ignorance is man's condition as a creature; the principle of the knowledge is the Divine knowledge; and the medium between ignorance and knowledge is objectively Divine revelation, and subjectively prophetic vision by man, in which he beholds with the eye of the mind what is shut and hid from the eye of his body." From these premises Dr. Kurtz goes on to argue that the pre-Adamic history of the past being _theologically_ in the same category as the yet undeveloped history of the future, that record of its leading events which occurs in the Mosaic narrative is simply _prophecy_ described backwards; and that, coming under the prophetic law, it ought of consequence to be subjected to the prophetic rule of exposition. There are some very ingenious reasonings employed in fortifying this point; and, after quoting from Eichhorn a passage to the effect that the opening chapter in Genesis is much rather a creative picture than a creative history, and from Ammon to the effect that the author of it evidently takes the position of a beholder of creation, the learned German concludes his general statement by remarking, that the scenes of the chapter are prophetic tableaux, each containing a leading phase of the drama of creation. "Before the eye of the seer," he says, "scene after scene is unfolded, until at length, in the seven of them, the course of creation, in its main _momenta_, has been fully represented." The revelation has every characteristic of prophecy by vision,--prophecy by eye-witnessing; and may be perhaps best understood by regarding it simply as an exhibition of the actual phenomena of creation presented to the mental eye of the prophet under the ordinary laws of perspective, and truthfully described by him in the simple language of his time. In our own country a similar view has been taken by the author of a singularly ingenious little work which issued about two years ago from the press of Mr. Constable of Edinburgh, "The Mosaic Record in Harmony with Geology."[17] The writer, however, exhibits, in dealing with his subject, the characteristic sobriety of the Anglo-Saxon mind; and while the leading features of his theory agree essentially with those of the Continental one, he does not press it so far. In canvassing the _form_ of the revelation made to Moses in the opening of Genesis, he discusses the nature of the inspiration enjoyed by that great prophet; and thus retranslates literally from the Hebrew the passage in which the Divine Being is himself introduced as speaking direct on the point in the controversy raised by Aaron and Miriam. "And He [the Lord] said, hear now my words: If he [Moses] were _your_ prophet [subordinate, or at least not superior, to the prophetess and the high priest], I, Jehovah, in the vision to him would make myself known: in the dream would I speak to him. Not so _my_ servant Moses [God's prophet, not theirs]; in all my house faithful is he. Mouth to mouth do I speak to him, and vision, but not in dark speeches; and likeness of Jehovah he beholds." Moses, then, was favored with "visions without dark speeches." Now, as implied in the passage thus retranslated, there is a grand distinction between symbolic and therefore _dark_ visions, and visions not symbolic nor dark. Visions addressed, as the word indicates, to the eye, may be obviously of a twofold character,--they may be either darker than words, or a great deal clearer than words. The vision, for instance, of future monarchies which Daniel saw symbolized under the form of monstrous animals had to be explained in words; the vision of Peter, which led to the general admission of the Gentiles into the Christian Church, had also virtually to be explained in words; they were both visions of the dark class; and revelation abounds in such. But there were also visions greatly clearer than words. Such, for instance, was the vision of the secret chamber of imagery, with its seventy men of the ancients of Israel given over to idolatry, which was seen by the prophet as he sat in his own house; and the vision of the worshippers of the sun in the inner court of the temple, witnessed from what was _naturally_ the same impossible point of view; with the vision of the Jewish women in the western gate "weeping for Thammuz," when, according to Milton's noble version, "The love tale Infected Sion's daughters with like heat, Whose wanton passions in the sacred porch Ezekiel saw, when, by the vision led, His eye surveyed the dark idolatries Of alienated Judah." Here, then, were there visions of scenes actually taking place at the time, which, greatly clearer than any merely verbal description, substituted the seeing of the eye for the hearing of the ear. And visions of this latter kind were enjoyed, argues the writer of this ingenious treatise, by the prophet Moses. One of the cases adduced may be best given in the author's own words. "Moses," he says, "received directions from God how to proceed in constructing the Tabernacle and its sacred furniture; and David also was instructed how the Temple of Solomon should be built. Let us hear Scripture regarding the nature of the directions given to these men:-- 'According unto the _appearance_ [literally sight, vision] which the Lord had showed unto Moses, so he made the _candlestick_.'--(Num. 5:4.) 'The whole in _writing_, by the hand of Jehovah upon me, he taught; the whole works of the pattern.'--(1 Chron. 28:19.) "There was thus a writing in the case of David; a sight or vision of the thing to be made in that of Moses." So far the author of the Treatise. He might have added further, that from the nature of things, the revelation to Moses in this instance _must_ have been "sight or vision," if, indeed, what is not in the least likely, the peculiar architecture and style of ornament used in the Tabernacle was not a borrowed style, already employed in the service of idolatry. An old, long established architecture can be adequately described by speech or writing; a new, original architecture can be adequately described only by pattern or model, that is, by sight or vision. Any intelligent cutter in stone or carver in wood could furnish to order, though the order were merely a verbal one, a Corinthian or Ionic capital; but no such mechanic, however skilful or ingenious, could furnish to order, if unprovided with a pattern or drawing, a _facsimile_ of one of the ornately sculptured capitals of Gloucester Cathedral or York Minster. To ensure a _facsimile_ in any such case, the originals, or representations of them, would require to be submitted to the eye,--not merely described to the ear. Nay, from the example given in the text,--that of the golden candlestick,--we have an instance furnished in recent times of the utter inadequacy of mere description for the purposes of the sculptor or artist. Ever since copperplate engravings and illustrated Bibles became comparatively common, representations of the branched candlestick taken from the written description have been common also. The candlestick on the arch of Titus, though not deemed an exact representation of the original one described in the Pentateuch, is now regarded,--correctly, it cannot be doubted,--as at least the nearest approximation to it extant. Public attention was first drawn to this interesting piece of sculpture in comparatively modern times; and it was then found that all the previous representations taken from the written description were widely erroneous. They only served to show, not the true outlines of the golden candlestick, but merely that inadequacy of verbal description for artistic purposes which must have rendered _vision_, or, in other words, optical representation, imperative in the case of Moses. Some of our most sober minded commentators take virtually the same view of this necessity of vision for ensuring the production of the true pattern of the Tabernacle. "The Lord," says Thomas Scott, "not only directed Moses by words how to build the Tabernacle and form its sacred furniture, but showed him a model exactly representing the form of every part, and the proportion of each to all the rest." There must have been clear optical vision in the case,--"vision without dark speeches." Such, too, was the character of other of the Mosaic visions, besides that of the "pattern" seen in the Mount. The burning bush, for instance, was a vision addressed to the eye; and seemed to come so palpably under the ordinary optical laws, that the prophet _drew near_ to examine the extraordinary phenomena which it exhibited. The visual or optical character of _some_ of the revelations made to Moses thus established, the writer goes on to inquire whether that special revelation which exhibits the generations of the heavens and earth in their order was not a visual revelation also. "Were the words that Moses wrote," he asks, "merely impressed upon his mind? Did he hold the pen, and another dictate? Or did he see in vision the scenes that he describes? The freshness and point of the narrative," he continues, "the freedom of the description, and the unlikelihood that Moses was an unthinking machine in the composition, all indicate that he saw in vision what he has here given us in writing. _He is describing from actual observation._" The writer remarks in an earlier portion of his treatise, that all who have adopted the theory advocated in the previous lecture,--the "Two Records," which was, I may state, published in a separate form, ere the appearance of his work, and which he does me the honor of largely quoting,--go upon the supposition that things during the Mosaic days are described as they would appear to the eye of one placed upon earth; and he argues that, as no man existed in those distant ages, a reason must be assigned for this _popular_ view of creation which the record is rightly assumed to take. And certainly, if it was in reality a view described from actual vision, the fact would form of itself an adequate reason. What man had actually seen, though but in dream or picture, would of course be described _as seen by man_: like all human history, it would, to borrow from Kurtz, be founded on eye-witnessing; and the fact that the Mosaic record of creation is _apparently_ thus founded, affords a strong presumption that it was in reality revealed, not by dictation, but by vision. Nor, be it remembered, has the recognition of a purely _optical_ character in the revelation been restricted to the assertion of any one theory of reconciliation. It was as certainly held by Chalmers and Dr. Pye Smith, as by Dr. Kurtz and the author of this treatise; nay, it has been recognized by not a few of their opponents also. Granville Penn, for instance, does not scruple to avow his belief, in his elaborate "Estimate of the Mineral and Mosaic Geologies," that both sun and moon were created on the first day of creation, though they did not become "_optically_ visible" until the fourth. "In truth, that the fourth day only rendered visible the sidereal creation of the first day, is manifested," he says, "by collating the transactions of the two days. On the first day, we are told generally, 'God divided the light, or day, and the darkness, or night;' but the physical agents which he employed for that division are not there declared. On the fourth day, we are told referentially, 'God commanded the lights [or luminaries] for dividing day and night, to give their light upon earth.' Here, then, it is evident from the retrospective implication of the latter description, that the lights or luminaries for dividing day and night, which were to give their light upon the earth for the first time on the fourth day, were the unexpressed physical agents by which God divided the day and night on the first day." Now, whatever may be thought of Mr. Penn's argument here, there can be no doubt that it demonstrates at least his own belief in the purely optical character of the Mosaic account of the sidereal creation. It is an account, he held, not of what God wrought on the first day in the heavens, but of what a human eye would have seen on the fourth day from the earth. And Moses Stuart, in his philological assault on the geologists, is scarce less explicit in his avowal of a similar belief. "Every one sees," he says, "that to speak of the sun as rising and setting, is to describe, in common parlance, what appears _optically_, that is, to our sensible view, as reality. But the history of creation is a different affair. In ONE RESPECT, indeed, there is a resemblance. _The historian everywhere speaks as an optical observer stationed on a point of our world, and surveying from this the heavens and the earth, and speaking of them as seen in this manner by his bodily eye._ The sun, and moon, and stars, are servants of the earth, lighted up to garnish and to cheer it, and to be the guardians of its times and seasons. Other uses he knows not for them: certainly of other uses he does not speak. The distances, magnitudes, orbicular motions, gravitating powers, and projectile forces of the planets and of the stars, are all out of the circle of his history, and probably beyond his knowledge. Inspiration does not make men _omniscient_. It does not teach them the scientific truths of astronomy, or chemistry, or botany, nor any science as such. Inspiration is concerned with teaching _religious_ truths, and such facts or occurrences as are connected immediately with illustrating, or with impressing them on the mind." Thus far Dr. Stuart and Mr. Penn,--men whose evidence on this special head must be sufficient to show that it is not merely geologists who have recognized an _optical_ or _visual_ character in the Mosaic history of creation. And certainly the inference deduced from the admitted _fact_, that is, the inference that the optical description must have been founded on a revelation addressed to the eye,--a revelation by vision,--does seem a fair and legitimate one. The revelation must have been either a revelation in words or ideas, or a revelation of scenes and events pictorially exhibited. Failing, however, to record its own history, it leaves the student equally at liberty, so far as _external_ evidence is concerned, to take up either view; while, so far as _internal_ evidence goes, the presumption seems all in favor of revelation by vision; for, while no reason can be assigned why, in a revelation by word or idea, appearances which took place ere there existed a human eye should be _optically_ described, nothing can be more natural or obvious than that they should be so described, had they been revealed by vision as a piece of _eye-witnessing_. It seems, then, at least eminently probable that such was the mode or form of the revelation in this case, and that he who saw by vision on the Mount the pattern of the Tabernacle and its sacred furniture, and in the Wilderness of Horeb the bush burning but not consumed,--types and symbols of the coming dispensation and of its Divine Author,--saw also by vision the _pattern_ of those successive pre-Adamic creations, animal and vegetable, through which our world was fitted up as a place of human habitation. The _reason_ why the drama of creation has been _optically_ described seems to be, that it was in reality _visionally_ revealed. A further question still remains: _If_ the revelation was by vision, that circumstance affords of itself a satisfactory reason why the description should be _optical_; and, on the other hand, since the description is decidedly _optical_, the presumption is of course strong that the revelation was by vision. But why, it may be asked, by vision? Can the presumption be yet further strengthened by showing that this visual mode or form was preferable to any other? Can there be a reason, in fine, assigned _for_ the _reason_,--for that revelation by vision which accounts for the optical character of the description? The question is a difficult one; but I think there can. There seems to be a peculiar fitness in a revelation made by vision, for conveying an account of creation to various tribes and peoples of various degrees of acquirement, and throughout a long course of ages in which the knowledge of the heavenly bodies or of the earth's history, that is, the sciences of astronomy and geology, did not at first exist, but in which ultimately they came to be studied and known. We must recognize such a mode as equally fitted for the earlier and the more modern times,--for the ages anterior to the rise of science, and the ages posterior to its rise. The prophet, by describing what he had actually seen in language fitted to the ideas of his time, would shock no previously existing prejudice that had been founded on the apparent evidence of the senses; he could as safely describe the moon as the second great light of creation, as he could the sun as its first great light, and both, too, as equally subordinate to the planet which we inhabit. On the other hand, an enlightened age, when it had come to discover this key to the description, would find it _optically_ true in all its details. But how differently would not a revelation have fared, in at least the earlier time, that was strictly scientific in its details,--a revelation, for instance, of the great truth demonstrated by Galileo, that the sun rests in the centre of the heavens, while the apparently immoveable earth sweeps with giddy velocity around it; or of the great truth demonstrated by Newton, that our ponderous planet is kept from falling off into empty space by the operation of the same law that impels a descending pebble towards the ground! A great miracle wrought in proof of the truth of the revelation might serve to enforce the belief of it on the generation to whom it had been given; but the generations that followed, to whom the miracle would exist as a piece of mere testimony, would credit, in preference, the apparently surer evidence of their senses, and become unbelievers. They would act, all unwittingly, on the principle of Hume's famous argument, and prefer to rest rather on their own _experience_ of the great phenomena of nature, than on the doubtful testimony of their ancestors, reduced in the lapse of ages to a dim, attenuated tradition. Nor would a geological revelation have fared better, in at least those periods intermediate between the darker and more scientific ages, in which ingenious men, somewhat skeptical in their leanings, cultivate literature, and look down rather superciliously on the ignorance and barbarism of the past. What would skeptics such as Hobbes and Hume have said of an opening chapter in Genesis that would describe successive periods,--first of molluscs, star-lilies, and crustaceans, next of fishes, next of reptiles and birds, then of mammals, and finally of man; and that would minutely portray a period in which there were lizards bulkier than elephants, reptilian whales furnished with necks slim and long as the bodies of great snakes, and flying dragons, whose spread of wing greatly more than doubled that of the largest bird? The world would assuredly not receive such a revelation. Nor, further, have scientific facts or principles been revealed to man which he has been furnished with the ability of observing or discovering for himself. It is according to the economy of revelation, that the truths which it exhibits should be of a kind which, lying beyond the reach of his ken, he himself could never have elicited. From every view of the case, then, a prophetic exhibition of the pre-Adamic scenes and events by vision seems to be the one best suited for the opening chapters of a revelation vouchsafed for the accomplishment of moral, not scientific purposes, and at once destined to be contemporary with every stage of civilization, and to address itself to minds of every various calibre, and every different degree of enlightenment. The statement of Dr. Kurtz, that as vision of pre-Adamic history comes under the same laws as vision of history still future, it ought therefore to be read by the same rules, craves reflection. "Since the source of knowledge for both kinds of history," we find him saying, "and not only the source, but the means, and manner, and way of coming to know, is the same, viz., the _eye-witness_ of the prophet's mental eye, it follows that the historical representation which he who thus comes to know, _projects_ [or portrays], in virtue of this eye-witnessing of his, holds the same relation to the reality in both the cases we speak of, and must be subjected to the same laws of exposition. We thus get this very important rule of interpretation, viz., that the representations of pre-human events, which rest upon revelation, are to be handled from the same point of view, and expounded by the same laws, as the prophecies and representations of future times and events, which also rest upon revelation. This, then, is the only proper point of view for scientific exposition of the Mosaic history of creation; that is to say, if we acknowledge that it proceeded from Divine revelation, not from philosophic speculation or experimental investigation, or from the ideas of reflecting men." There is certainly food for thought in this striking and original view; and there is at least one simple rule of prophetic exposition which may be applied to the pre-Adamic history, in accordance with the principle which it suggests. After all that a scientific theology has done for the right interpretation of prophecy, we find the prediction always best read by the light of its accomplishment. The event which it foretold forms its true key; and when this key is wanting, all is uncertainty. The past is comparatively clear. The hieroglyphic forms which crowd the anterior portions of the prophetic tablet are found wonderfully to harmonize (men such as the profound Newton being the judges) with those great historic events, already become matter of history, which they foreshadowed and symbolized; but, on the other hand, the hieroglyphics which occupy the tablet's posterior portion,--the hieroglyphics that symbolize events still future,--are invincibly difficult and inexplicable. I have read several works on prophecy produced in the last age, in which the writers were bold enough to quit the clue with which history furnishes the student of fulfilled prophecy, and, with the prophecies yet unfulfilled as their guide, to plunge into a troubled sea of speculation regarding the history of the future. And I have found that in every instance they were deplorably at fault regarding even the events that were nearest at hand at the time. History is thus the surest interpreter of the revealed prophecies which referred to events _posterior_ to the times of the prophet. In what shall we find the surest interpretation of the revealed _prophecies_ that referred to events _anterior_ to his time? In what light, or on what principle, shall we most correctly read the prophetic drama of creation? In the light, I reply, of scientific discovery,--on the principle that the clear and certain must be accepted, when attainable, as the proper exponents of the doubtful and obscure. What fully developed history is to the prophecy which of old looked forwards, fully developed science is to the prophecy which of old looked backwards. Scarce any one will question whether that portion of the creation drama which deals with the heavenly bodies ought to be read in the light of established astronomic discovery or no; for, save by perhaps a few of Father Cullen's monks, who can still hold that the sun moves round the earth, and is only six feet in diameter, all theologians have now received the astronomic doctrines, and know that they rest upon a basis at least as certain as any of the historic events symbolized in fulfilled prophecy. And were we to challenge for the established geologic doctrines a similar place and position with respect to those portions of the drama which deal with the two great kingdoms of nature, plant and animal, we might safely do so in the belief that the claim will be one day as universally recognized as the astronomic one is now. On this principle there may, of course, be portions of the _prophetic_ pre-Adamic past of as doubtful interpretation at the present time, from the imperfect development of physical science, as is any portion of the prophetic future from the imperfect development of historic events. The science necessary to the interpretation of the one may be as certainly still to discover as the events necessary to the interpretation of the other may be still to take place. Three centuries have not yet passed since astronomic science was sufficiently developed to form a true key to the various notices of the heavenly bodies which occur in Scripture; among the others, to the notice of their final appearance on the _fourth_ day of creation. Little more than half a century has yet passed since geologic science was sufficiently developed to influence the interpretation given of the three _other_ days' work. And respecting the work of at least the first and second days, more especially that of the second, we can still but vaguely guess. The science necessary to the right understanding of these portions of the prophetic record has still, it would seem, to be developed, if, indeed, it be destined at all to exist; and at present we can indulge in but doubtful surmises regarding them. What may be termed the three _geologic_ days,--the third, fifth, and sixth,--may be held to have extended over those Carboniferous periods during which the great plants were created,--over those Oolitic and Cretacious periods during which the great sea monsters and birds were created,--and over those Tertiary periods during which the great terrestrial mammals were created. For the intervening or fourth day we have that wide space represented by the Permian and Triassic periods, which, less conspicuous in their floras than the period that went immediately before, and less conspicuous in their faunas than the periods that came immediately after, were marked by the decline, and ultimate extinction, of the Palæozoic forms, and the first partially developed beginnings of the Secondary ones. And for the first and second days there remain the great Azoic period, during which the immensely developed gneisses, mica schists, and primary clay slates, were deposited, and the two extended periods represented by the Silurian and Old Red Sandstone systems. These, taken together, exhaust the geologic scale, and may be named in their order as, _first_, the Azoic day or period; _second_, the Silurian and Old Red Sandstone day or period; _third_, the Carboniferous day or period; _fourth_, the Permian and Triassic day or period; _fifth_, the Oolitic and Cretaceous day or period; and _sixth_, the Tertiary day or period. Let us attempt conceiving how they might have appeared pictorially, if revealed in a series of visions to Moses, as the successive scenes of a great air-drawn panorama. During the Azoic period, ere life appears to have begun on our planet, the temperature of the earth's crust seems to have been so high, that the strata, at first deposited apparently in water, passed into a semi-fluid state, became strangely waved and contorted, and assumed in its composition a highly crystalline character. Such is peculiarly the case with the fundamental or gneiss deposits of the period. In the overlying mica schist there is still much of contortion and disturbance; whereas the clay slate, which lies over all, gives evidence, in its more mechanical texture, and the regularity of its strata, that a gradual refrigeration of the general mass had been taking place, and that the close of the Azoic period was comparatively quiet and cool. Let us suppose that during the earlier part of this period of excessive heat the waters of the ocean had stood at the boiling point even at the surface, and much higher in the profounder depths, and further, that the half-molten crust of the earth, stretched out over a molten abyss, was so thin that it could not support, save for a short time, after some convulsion, even a small island above the sea level. What, in such circumstances, would be the aspect of the scene, optically exhibited from some point in space elevated a few hundred yards over the sea? It would be simply a blank, in which the intensest glow of fire would fail to be seen at a few yards' distance. An inconsiderable escape of steam from the safety-valve of a railway engine forms so thick a screen, that, as it lingers for a moment, in the passing, opposite the carriage windows, the passengers fail to discern through it the landscape beyond. A continuous stratum of steam, then, that attained to the height of even our present atmosphere, would wrap up the earth in a darkness gross and palpable as that of Egypt of old,--a darkness through which even a single ray of light would fail to penetrate. And beneath this thick canopy the unseen deep would literally "boil as a pot," wildly tempested from below; while from time to time more deeply seated convulsion would upheave sudden to the surface vast tracts of semi-molten rock, soon again to disappear, and from which waves of bulk enormous would roll outwards, to meet in wild conflict with the giant waves of other convulsions, or return to hiss and sputter against the intensely heated and fast foundering mass, whose violent upheaval had first elevated and sent them abroad. Such would be the probable state of things during the times of the earlier gneiss and mica schist deposits,--times buried deep in that chaotic night or "evening" which must have continued to exist for mayhap many ages after that beginning of things in which God created the heavens and the earth, and which preceded the first day. To a human eye stationed within the cloud, all, as I have said, must have been thick darkness: to eyes Divine, that could have looked through the enveloping haze, the appearance would have been that described by Milton, as seen by angel and archangel at the beginning of creation, when from the gates of heaven they looked down upon chaos:-- "On heavenly ground they stood, and from the shore They viewed the vast immeasurable abyss, Outrageous as a sea, dark, wasteful, wild, Up from the bottom turned by furious _heat_ And surging waves, as mountains to assault Heaven's height, and with the centre mix the pole." At length, however, as the earth's surface gradually cooled down, and the enveloping waters sunk to a lower temperature,--let us suppose, during the latter times of the mica schist, and the earlier times of the clay slate,--the steam atmosphere would become less dense and thick, and at length the rays of the sun would struggle through, at first doubtfully and diffused, forming a faint twilight, but gradually strengthening as the latter ages of the slate formation passed away, until, at the close of the great primary period, day and night,--the one still dim and gray, the other wrapped in a pall of thickest darkness,--would succeed each other as now, as the earth revolved on its axis, and the unseen luminary rose high over the cloud in the east, or sunk in the west beneath the undefined and murky horizon. And here again the _optical_ appearance would be exactly that described by Milton:-- "'Let there be light,' said God, and forthwith light Ethereal, first of things, quintessence pure, Sprung from the deep, and from her native east To journey through the airy gloom began, Sphered in a radiant cloud, for yet the sun Was not: she in a cloudy tabernacle Sojourned the while. God saw the light was good, And light from darkness by the hemisphere Divided: light the day, and darkness night, He named. This was the first day, even and morn." The second day's work has been interpreted variously, according to the generally received science of the times of the various commentators who have dealt with it. Even in Milton, though the great poet rejected the earlier idea of a solid firmament, we find prominence given to that of a vast hollow sphere of "circumfluous waters," which, by encircling the atmosphere, kept aloof the "fierce extremes of chaos." Later commentators, such as the late Drs. Kitto and Pye Smith, hold that the Scriptural analogue of the _firmament_ here--by the way, a Greek, not a Hebrew idea, first introduced into the Septuagint--was in reality simply the atmosphere with its clouds. "The historian" [Moses], says Dr. Kitto, "speaks as things would have appeared to a spectator at the time of the creation. A portion of the heavy watery vapor had flown into the upper regions, and rested there in dense clouds, which still obscured the sun; while below, the whole earth was covered with water. Thus we see the propriety with which the firmament is said to have divided the waters from the waters." It is certainly probable that in a vision of creation the atmospheric phenomena of the second great act of the creation drama might have stood out with much greater prominence to the prophetic eye placed in the circumstances of a natural one, than any of its other appearances. The invertebrate life of the Silurian period, or even the ichthyic life of the earlier Old Bed Sandstone period, must have been comparatively inconspicuous from any sub-ærial point of view elevated but a few hundred feet over the sea level. Even the few islets of the latter ages of the period, with their ferns, lepidodendra, and coniferous trees, forming, as they did, an exceptional feature in these ages of vast oceans, and of organisms all but exclusively marine, may have well been excluded from a representative diorama that exhibited optically the grand characteristics of the time. Further, it seems equally probable that the introduction of organized existence on our planet was preceded by a change in the atmospheric conditions which had obtained during the previous period, in which the earth had been a desert and empty void. We know that just before the close of the Silurian ages terrestrial plants had appeared, and that before the close of the Old Red Sandstone ages, air-breathing animals had been produced; and infer that the atmosphere in which both could have existed must have been considerably different from that which lay dark and heavy over the bare hot rocks, and tenantless, steam-emitting seas, of the previous time. Under a gray, opaque sky, in which neither sun nor moon appear, we are not unfrequently presented with a varied drapery of clouds,--a drapery varied in form, though not in color: bank often seems piled over bank, shaded beneath and lighter above; or the whole breaks into dappled cloudlets, which bear--to borrow from the poetic description of Bloomfield--the "beauteous semblance of a flock at rest." And if such ærial draperies appeared in this early period, with the clear space between them and the earth which we so often see in gray, sunless days, the optical aspect must have been widely different from that of the previous time, in which a dense vaporous fog lay heavy upon rock and sea, and extended from the earth's surface to the upper heights of the atmosphere. The third day's vision seems to be more purely geological in its character than either of the previous two. Extensive tracts of dry land appear, and there springs up over them, at the Divine command, a rank vegetation. And we know that what seems to be the corresponding Carboniferous period, unlike any of the preceding ones, was remarkable for its great tracts of terrestrial surface, and for its extraordinary flora. For the first time dry land, and organized bodies at once bulky enough, and exhibited in a medium clear enough, to render them conspicuous objects in a distant prospect, appear in the Mosaic drama; and we still find at once evidence of the existence of extensive though apparently very flat lands, and the remains of a wonderfully gigantic and abundant vegetation, in what appear to be the rocks of this period. The vision of the fourth day, like that of the second, pertained not to the earth, but to the _heavens_; the sun, moon, and stars become visible, and form the sole subjects of the prophetic description. And just as, during the second period, the earth would in all probability have failed to furnish any feature of mark enough to divert a human eye placed on a commanding station from the conspicuous _atmospheric_ phenomena of the time, so it seems equally probable that during this fourth period it would have failed to furnish any feature of mark enough to divert a human eye from the still more conspicuous _celestial_ phenomena of the time. As has been already incidentally remarked, the Permian and Triassic periods were "epochs"--to employ the language of the late Professor Edward Forbes--"of great poverty of production of generic types." On the other hand, the appearance for the first time of sun, moon, and stars, must have formed a scene well suited to divert the attention of the seer from every other. Nor (as has been somewhat rashly argued by Dr. Kitto and several others) does it seem irrational to hold that three very extended _periods_ should have elapsed ere the sidereal heavens became visible on earth. Addison's popular illustration, drawn from one of the calculations of Newton, made in an age when comets were believed to be solid bodies, rendered the reading public familiar, considerably more than a century ago, with the vast time which large bodies greatly heated would take in cooling. "According to Sir Isaac Newton's calculation," said the exquisitely classical essayist, "the comet that made its appearance in 1680 imbibed so much heat by its approaches to the sun, that it would have been two thousand times hotter than red hot iron had it been a globe of that metal; and that, supposing it as big as the earth, and at the same distance from the sun, it would be fifty thousand years in cooling before it recovered its natural temper." Such was an estimate of the philosopher, that excited no little wonder in the days of our great grandfathers, for the vast time which it demanded; and, now that the data on which such a calculation ought to be founded are better known than in the age of Newton, yet more time would be required still. It is now ascertained, from the circumstance that no dew is deposited in our summer evenings save under a clear sky, that even a thin covering of cloud,--serving as a robe to keep the earth warm,--prevents the surface heat of the planet from radiating into the spaces beyond. And such a cloud, thick and continuous, as must have wrapped round the earth as with a mantle during the earlier geologic periods, must have served to retard for many ages the radiation, and consequently the reduction, of that internal heat of which it was itself a consequence. Further, the rocks and soils that form the surface of our globe would be much more indifferent conductors of heat than the iron superficies of Newton's ball, and would serve yet more to lengthen out the cooling process. Nor would a planet covered over for ages with a thick screen of vapor be a novelty even yet in the universe. It is doubtful whether astronomers have ever yet looked on the face of Mercury: it is at least very generally held that hitherto only his clouds have been seen. Even Jupiter, though it is thought his mountains have been occasionally detected raising their peaks through openings in his cloudy atmosphere, is known chiefly by the dark shifting bands that, streaking his surface in the line of his trade winds, belong not to his body, but to his thick dark covering. It is questionable whether a human eye on the surface of Mercury would ever behold the sun, notwithstanding his near proximity; nor would he be often visible, if at all, from the surface of Jupiter. Nor, yet further, would a warm steaming atmosphere muffled in clouds have been unfavorable to a rank, flowerless vegetation like that of the Coal Measures. There are moist, mild, cloudy days of spring and early Summer that rejoice the heart of the farmer, for he knows how conducive they are to the young growth on his fields. The Coal Measure climate would have consisted of an unbroken series of these, with mayhap a little more of cloud and moisture, and a great deal more of heat. The earth would have been a vast greenhouse covered with smoked glass; and a vigorous though mayhap loosely knit and faintly colored vegetation would have luxuriated under its shade. The fifth and sixth days,--that of winged fowl and great sea monsters, and that of cattle and beasts of the earth,--I must regard as adequately represented by those Secondary ages, Oolitic and Cretaceous, during which birds were introduced, and reptiles received their greatest development, and those Tertiary ages during which the gigantic mammals possessed the earth and occupied the largest space in creation. To the close of this latter period,--the evening of the sixth day,--man belongs,--at once the last created of terrestrial creatures, and infinitely beyond comparison the most elevated in the scale; and with man's appearance on the scene the days of creation end, and the Divine Sabbath begins,--that Sabbath of rest from creative labor of which the proper work is the moral development and elevation of the species, and which will terminate only with the full completion of that sublime task on the full accomplishment of which God's eternal purposes and the tendencies of man's progressive nature seem alike directed. Now, I am greatly mistaken if we have not in the six geologic periods all the elements, without misplacement or exaggeration, of the Mosaic drama of creation. I have referred in my brief survey to extended periods. It is probable, however, that the prophetic vision of creation, if such was its character, consisted of only single representative scenes, embracing each but a point of time; it was, let us suppose, a diorama, over whose shifting pictures the curtain rose and fell six times in succession,--once during the Azoic period, once during the earlier or middle Palæozoic period, once during the Carboniferous period, once during the Permian or Triassic period, once during the Oolitic or Cretaceous period, and finally, once during the Tertiary period. Dr. Kurtz holds, taking the Sabbath into the series, that the division into _seven_ scenes or stages may have been regulated with reference to the importance and sacredness of the mythic number seven,--the symbol of completeness or perfection; but the suggestion will perhaps not now carry much weight among the theologians of Britain, whatever it might have done two centuries ago. It is true, that creation _might_ have been exhibited, not by seven, but by seven hundred, or even by seven thousand scenes; and that the accomplished man of science, skilled in every branch of physics, might have found something distinct in them all. But not the less do the seven, or rather the six, exhibited scenes appear to be not symbolic or mystical, at least not exclusively symbolic or mystical, but truly representative of successive periods, strongly distinctive in their character, and capable, with the three geologic days as given points in the problem, of being treated geologically. Another of the questions raised, both by the German doctor and the writer in our own country, must be recognized as eminently suggestive. "We treat the history of creation," says Dr. Kurtz, "with its six days' work, as a connected series of so many prophetic visions. The appearance and evanishing of each such vision seem to the seer as a morning and an evening, apparently because these were presented to him as an increase and decrease of light, like morning and evening twilight." And we find the Scottish writer taking essentially the same view. "Each day contains," he says, "the description of what he [Moses] beheld in a single vision, and when it faded it was twilight. There is nothing forced in supposing that, after the vision had for a time illumined the fancy of the seer, it was withdrawn from his eyes, in the same way that the landscape becomes dim on the approach of evening.... From this point of view, a 'day' can only mean the period during which the Divinely enlightened fancy of the seer was active. When all continued bright and manifest before his entranced but still conscious soul, it was 'day' or 'light.' When the dimness of departing enlightenment fell upon the scene, it was the evening twilight." The _days_, then, are removed, we find, by the holders of this view, altogether from the province of chronology to the province of prophetic vision; they are represented simply as parts of the exhibited scenery, or rather as forming the measures of the apparent time during which the scenery _was_ exhibited. We must also hold, however, that in the character of symbolic days they were as truly representative of the lapse of foregone periods of creation as the scenery itself was representative of the creative work accomplished in these periods. For if the apparent days occurred in only the vision, and were not symbolic of foregone periods, they could not have been transferred with any logical propriety from the vision itself to that which the vision represented, as we find done in what our Shorter Catechism terms "the reason annexed to the Fourth Commandment."[18] The days must have been prophetic days, introduced, indeed, into the panorama of creation as mayhap mere openings and droppings of the curtain, but not the less symbolic of that series of successive periods, each characterized by its own productions and events, in which creation itself was comprised. Nothing more probable, however, than that even Moses himself may have been unacquainted with the _extent_ of the periods represented in the vision; nay, he may have been equally unconscious of the actual extent of the seeming days by which they were symbolized. "Visions without dark speeches,"--visions, not of symbolic apparitions, but of actual existences and events, past or present,--may, nay must, have differed from what may be termed the dark hieroglyphic visions; but we find in all visions an element of mere representative value introduced when they deal with time, and that they occur as if wholly outside its pale. These creation "days" seem, in relation to what they typify, to have been, if I may so express myself, the mere _modules_ of a graduated scale. Such a description of the creative vision of Moses as the one given by Milton of that vision of the future, which he represents as conjured up before Adam by the archangel, would be a task rather for the scientific poet than for the mere practical geologist or sober theologian. Let us suppose that it took place far from man, in an untrodden recess of the Midian desert, ere yet the vision of the burning bush had been vouchsafed; and that, as in the vision of St. John in Patmos, voices were mingled with scenes, and the ear as certainly addressed as the eye. A "great darkness" first falls upon the prophet, like that which in an earlier age fell upon Abraham, but without the "horror;" and, as the Divine Spirit moves on the face of the wildly troubled waters, as a visible aurora enveloped by the pitchy cloud, the great doctrine is orally enunciated, that "in the beginning God created the heavens and the earth." Unreckoned ages, condensed in the vision into a few brief moments, pass away; the creative voice is again heard, "Let there be light," and straightway a gray diffused light springs up in the east, and, casting its sickly gleam over a cloud-limited expanse of steaming, vaporous sea, journeys through the heavens towards the west. One heavy, sunless day is made the representative of myriads; the faint light waxes fainter,--it sinks beneath the dim, undefined horizon; the first scene of the drama closes upon the seer; and he sits awhile on his hill-top in darkness, solitary but not sad, in what seems to be a calm and starless night. The light again brightens,--it is day; and over an expanse of ocean without visible bound the horizon has become wider and sharper of outline than before. There is life in that great sea,--invertebrate, mayhap also ichthyic, life; but, from the comparative distance of the point of view occupied by the prophet, only the slow roll of its waves can be discerned, as they rise and fall in long undulations before a gentle gale; and what most strongly impresses the eye is the change which has taken place in the atmospheric scenery. That lower stratum of the heavens occupied in the previous vision by seething steam, or gray, smoke-like fog, is clear and transparent; and only in an upper region, where the previously invisible vapor of the tepid sea has thickened in the cold, do the clouds appear. But there, in the higher strata of the atmosphere they lie, thick and manifold,--an upper sea of great waves, separated from those beneath by the transparent firmament, and, like them too, impelled in rolling masses by the wind. A mighty advance has taken place in creation; but its most conspicuous optical sign is the existence of a transparent atmosphere,--of a firmament, stretched out over the earth, that separates the waters above from the waters below. But darkness descends for the third time upon the seer, for the evening and the morning have completed the second day. Yet again the light rises under a canopy of cloud; but the scene has changed, and there is no longer an unbroken expanse of sea. The white surf breaks, at the distant horizon, on an insulated reef, formed mayhap by the Silurian or Old Red coral zoophytes ages before, during the bygone yesterday; and beats in long lines of foam, nearer at hand, against a low, winding shore, the seaward barrier of a widely spread country. For at the Divine command the land has arisen from the deep,--not inconspicuously and in scattered islets, as at an earlier time, but in extensive though flat and marshy continents, little raised over the sea level; and a yet further fiat has covered them with the great carboniferous flora. The scene is one of mighty forests of cone-bearing trees,--of palms, and tree-ferns, and gigantic club mosses, on the opener slopes, and of great reeds clustering by the sides of quiet lakes and dark rolling rivers. There is deep gloom in the recesses of the thicker woods, and low thick mists creep along the dank marsh or sluggish stream. But there is a general lightening of the sky over head; as the day declines, a redder flush than had hitherto lighted up the prospect falls athwart fern covered bank and long withdrawing glade. And while the fourth evening has fallen on the prophet, he becomes sensible, as it wears on, and the fourth dawn approaches, that yet another change has taken place. The Creator has spoken, and the stars look out from openings of deep unclouded blue; and as day rises, and the planet of morning pales in the east, the broken cloudlets are transmuted from bronze into gold, and anon the gold becomes fire, and at length the glorious sun arises out of the sea, and enters on his course rejoicing. It is a brilliant day; the waves, of a deeper and softer blue than before, dance and sparkle in the light; the earth, with little else to attract the gaze, has assumed a garb of brighter green; and as the sun declines amid even richer glories than those which had encircled his rising, the moon appears full orbed in the east,--to the human eye the second great luminary of the heavens,--and climbs slowly to the zenith as night advances, shedding its mild radiance on land and sea. Again the day breaks; the prospect consists, as before, of land and ocean. There are great pine woods, reed-covered swamps, wide plains, winding rivers, and broad lakes; and a bright sun shines over all. But the landscape derives its interest and novelty from a feature unmarked before. Gigantic birds stalk along the sands, or wade far into the water in quest of their ichthyic food; while birds of lesser size float upon the lakes, or scream discordant in hovering flocks, thick as insects in the calm of a summer evening, over the narrower seas, or brighten with the sunlit gleam of their wings the thick woods. And ocean has its monsters: great "_tanninim_" tempest the deep, as they heave their huge bulk over the surface, to inhale the life-sustaining air; and out of their nostrils goeth smoke, as out of a "seething pot or cauldron." Monstrous creatures, armed in massive scales, haunt the rivers, or scour the flat rank meadows; earth, air, and water are charged with animal life; and the sun sets on a busy scene, in which unerring instinct pursues unremittingly its few simple ends,--the support and preservation of the individual, the propagation of the species, and the protection and maintenance of the young. Again the night descends, for the fifth day has closed; and morning breaks on the sixth and last day of creation. Cattle and beasts of the fields graze on the plains; the thick-skinned rhinoceros wallows in the marshes; the squat hippopotamus rustles among the reeds, or plunges sullenly into the river; great herds of elephants seek their food amid the young herbage of the woods; while animals of fiercer nature,--the lion, the leopard, and the bear,--harbor in deep caves till the evening, or lie in wait for their prey amid tangled thickets, or beneath some broken bank. At length, as the day wanes and the shadows lengthen, man, the responsible lord of creation, formed in God's own image, is introduced upon the scene, and the work of creation ceases forever upon the earth. The night falls once more upon the prospect, and there dawns yet another morrow,--the morrow of God's rest,--that Divine Sabbath in which there is no more creative labor, and which, "blessed and sanctified" beyond all the days that had gone before, has as its special object the moral elevation and final redemption of man. And over _it_ no evening is represented in the record as falling, for its special work is not yet complete. Such seems to have been the sublime panorama of creation exhibited in vision of old to "The shepherd who first taught the chosen seed, In the beginning how the heavens and earth Rose out of chaos;" and, rightly understood, I know not a single scientific truth that militates against even the minutest or least prominent of its details. LECTURE FIFTH. GEOLOGY IN ITS BEARINGS ON THE TWO THEOLOGIES. PART I. The science of the geologist seems destined to exert a marked influence on that of the natural theologian. For not only does it greatly add to the materials on which the natural theologian founds his deductions, by adding to the organisms, plant and animal, of the present creation the extinct organisms of the creations of the past, with all their extraordinary display of adaptation and design; but it affords him, besides, materials peculiar to itself, in the history which it furnishes both of the appearance of these organisms in time, and of the wonderful order in which they were chronologically arranged. Not only--to borrow from Paley's illustration--does it enable him to argue on the old grounds, from the contrivance exhibited in the _watch_ found on the moor, that the watch could not have lain upon the moor forever; but it establishes further, on different and more direct evidence, that there was a time when absolutely the watch was not there; nay, further, so to speak, that there was a previous time in which no watches existed at all, but only water clocks; yet, further, that there was a time in which there were not even water clocks, but only sundials; and further, an earlier time still in which sundials were not, nor any measurers of time of any kind. And this is distinct ground from that urged by Paley. For, besides holding that each of these contrivances must have had in turn an originator or contriver, it adds historic fact to philosophic inference. Geology takes up the master volume of the greatest of the natural theologians, and, after scanning its many apt instances of palpable design, drawn from the mechanism of existing plants and animals, authoritatively decides that not one of these plants or animals had begun to be in the times of the Chalk; nay, that they all date their origin from a period posterior to that of the Eocene. And the fact is, of course, corroborative of the inference. "That well constructed edifice," says the natural theologian, "cannot be a mere _lusus naturæ_, or chance combination of stones and wood; it must have been erected by a builder." "Yes," remarks the geologist, "it was erected some time during the last nine years. I passed the way ten years ago, and saw only a blank space where it now stands." Nor does the established fact of an absolute beginning of organic being seem more pregnant with important consequences to the science of the natural theologian than the fact of the peculiar order in which they begin to be. The importance of the now demonstrated fact, that all the living organisms which exist on earth had a beginning, and that a time was when they were not, will be best appreciated by those who know how much, and, it must be added, how unsuccessfully, writers on the evidences have labored to convict of an absurdity, on this special head, the atheistic assertors of an infinite series of beings. Even Robert Hall (in his famous Sermon on Modern Infidelity) could but play, when he attempted grappling with the subject, upon the words _time_ and _eternity_, and strangely argue, that as each member of an infinite series must have begun in _time_, while the succession itself was _eternal_, it was palpably absurd to ask us to believe in a _succession_ of beings that was thus infinitely earlier than any of the beings themselves which composed the succession. And Bentley, more perversely ingenious still, could assert, that as each of the individuals in an infinite series must have consisted of many parts,--that as each man in such a series, for instance, must have had ten fingers and ten toes,--it was palpably absurd to ask us to believe in an infinity which thus comprised many infinities,--ten infinities of fingers, for example, and ten infinities of toes. The infidels had the better in this part of the argument. It was surely easy enough to show against the great preacher, on the one hand, that _time_ in such a question is but a mere word that means simply a certain limited or definite period which had a beginning, whereas eternity means an unlimited and undefinable period which had no beginning;--that his seeming argument was no argument, but merely a sort of verbal play on this difference of signification in the words;--further, that man could conceive of an infinite series, whether extended in infinite space, or subsisting in infinite time, just as well as he could conceive of any other infinity, and in the same way; and that the only mode of disproving the possibility of such a series would be to show, what of course cannot be shown, that in conceiving of it in the progressive mode in which, according to Locke, man can alone conceive of the infinite or the eternal, there would be a point reached at which it would be impossible for him to go on adding millions on millions to the previous sum. The symbolic "_ad infinitum_" could be made as adequately representative in the case of an infinite series of men or animals in unlimited time, as of an infinite series of feet or inches in unlimited space, or of an infinite series of hours or minutes in the past eternity. And as for Bentley, on the other hand, he ought surely to have known that all infinities are not equal, seeing that Newton had expressly told him so in the second of his four famous letters; but that, on the contrary, one infinity may be not only ten times greater than another infinity, but even infinitely greater than another infinity; and that so the conception of an infinity of men possessed of ten infinities of fingers and toes is in no respect an absurdity. Of the three infinities possible in space, the second is infinitely greater than the first, and the third infinitely greater than the second. A line infinitely produced is capable of being divided into--that is, consists of--an infinity of given parts; a plane infinitely extended is capable of being divided into an infinity of infinitely divisible lines; and a cube, that is, a solid, infinitely expanded, is capable of being divided into an infinity of infinitely divisible planes. In fine, metaphysic theology furnishes no argument against the infinite series of the atheist. But geology does. Every plant and animal that now lives upon earth began to be during the great Tertiary period, and had no place among the plants and animals of the great Secondary division. We can trace several of our existing quadrupeds, such as the badger, the hare, the fox, the red deer, and the wild cat, up till the earlier times of the Pleistocene; and not a few of our existing shells, such as the great pecten, the edible oyster, the whelk, and the Pelican's-foot shell, up till the greatly earlier times of the Coraline Crag. But at certain definite lines in the deposits of the past, representative of certain points in the course of time, the existing mammals and molluscs cease to appear, and we find their places occupied by other mammals and molluscs. Even such of our British shells as seem to have enjoyed as species the longest term of life cannot be traced beyond the times of the Pliocene deposits. We detect their remains in a perfect state of keeping in almost every shell-bearing bed, till we reach the Red and Coraline Crags, where we find them for the last time; and, on passing into older and deeper lying beds, we see their places taken by other shells, of species altogether distinct. The very common shell _Purpura lapillus_, for instance, is found in our raised beaches, in our Clyde beds, in our boulder clays and mammaliferous crags, and, finally, in the Red Crag, beyond which it fails to appear. And such also is the history of the common edible mussel and common periwinkle; whereas the common edible cockle, and common edible pecten (_P. opercularis_) occur not only in all these successive beds, but in the Coral Crag also. They are older by a whole deposit than their present contemporaries, the mussel and periwinkle; and these, in turn, seem of older standing than shells such as _Murex erinaceus_, that has not been traced beyond the times of the mammaliferous crag, or than shells such as _Scrobicularia piperata_, that has not been detected in more ancient deposits than raised sea beaches of the later periods, and the elevated bottoms of old estuaries and lagoons. We thus know, that in certain periods, nearer or more remote, all our existing molluscs _began_ to exist, and that they had no existence during the previous periods; which were, however, richer in animals of the same great molluscan group than the present time. Our British group of recent marine shells falls somewhat short of _four_ hundred species;[19] whereas the group characteristic of the older Miocene deposits, largely developed in those districts of France which border on the Bay of Biscay, and more sparingly in the south of England, near Yarmouth, comprises more than six hundred species. Nearly an equal number of still older shells have been detected in a single deposit of the Paris basin,--the _Calcaire grossier_; and a good many more in a more ancient formation still, the London Clay. On entering the Chalk, we find a yet older group of shells, wholly unlike any of the preceding ones; and in the Oolite and Lias yet other and different groups. And thus group preceded group throughout all the Tertiary, Secondary, and Palæozoic periods; some of them remarkable for the number of species which they contained, others for the profuse abundance of their individual specimens, until, deep in the rocks at the base of the Silurian system, we detect what seems to be the primordial group, beneath which only a single animal organism is known to occur,--the _Oldhamia antiqua_,--a plant-like zoophyte, akin apparently to some of our recent sertularia, (See fig. 5, page 48.) Each of the extinct groups had, we find, a beginning and an end;--there is not in the wide domain of physical science a more certain fact; and every species of the group which now exists had, like all their predecessors on the scene, their beginning also. The "infinite series" of the atheists of former times can have no place in modern science: all organic existences, recent or extinct, vegetable or animal, have had their beginning;--there was a time when they were not. The geologist can indicate that time, if not by years, at least by periods, and show what its relations were to the periods that went before and that came after; and as it is equally a recognized truth on both sides of the controversy, that as something now exists, something must have existed forever, and as it must now be not less surely recognized, that that something was not the race of man, nor yet any other of the many races of man's predecessors or contemporaries, the question, What then was that something? comes with a point and directness which it did not possess at any former time. By what, or through whom, did these races of nicely organized plants and animals begin to be? Hitherto at least there has been but one reply to the question originated on the skeptical side. All these races, it is said, have been _developed_, in the long course of ages, into what they now are, as the young animal is developed in the womb, or the young plant is developed from the seed. Topsy, in the novel, "'spected that she was not made, but growed;" and the only class of opponents which the geological theist finds in the field which his science has laid open to the world is a class that hold by the philosophy of Topsy. Let me briefly remark regarding this development hypothesis, with which I have elsewhere dealt at considerable length, that while the facts of the geologist are demonstrably such, that is, truths capable of proof, the hypothesis is a mere dream, unsupported by a shadow of evidence. A man of a lively imagination could no doubt originate many such dreams; nay, we know that in the dark ages dreams of the kind were actually originated. The _Anser Bernicla_, or barnacle goose, a common winter visitant of our coasts, was once believed to be developed out of decaying wood long submerged in sea water: and one of our commonest cirripedes or barnacles, _Lepas anatifera_, still bears, in its specific name of the goose-producing _lepas_, evidence that it was the creature specially recognized by our ancestors as the half-developed goose. As if in memory of this old development legend, the bird still bears the name of the barnacle, and the barnacle of the bird; and we know further, that very intelligent men for their age, such as Gerardes the herbalist (1597), and Hector Boece the historian (1524), both examined these shells, and, knowing but little of comparative anatomy, were satisfied that the animal within was the partially developed embryo of a fowl. Such was one of the fables gravely credited as a piece of natural history in Britain about three centuries ago, and such was the kind of evidence by which it was supported. And we know that the followers of Epicurus received from their master, without apparent suspicion, fables still more extravagant, and that wanted even such a shadow of proof to support them as satisfied the herbalist and the historian. The Epicureans at least professed to believe that the earth, after spontaneously producing herbs and trees, began to produce in great numbers mushroom-like bodies, that, when they came to maturity, burst open, giving egress each to a young animal, which proved the founder of a race; and that thus, in succession, all the members of the animal kingdom were ushered into existence. But whether the dream be that of the Epicureans of classic times, or that of the naturalists of the middle ages, or that of the Lamarckians of our own days, it is equally a dream, and can have no place assigned to it among either the solid facts or the sober deductions of science. Nay, the dream of the Lamarckians labors under a special disadvantage, from which the dreams of the others are free. If some modern Boece or Epicurus were to assert that at certain definite periods, removed from fifteen to fifty thousand years from the present time, all our existing animals were developed from decaying wood, or from a wonderful kind of mushrooms that the earth produced only once every ten thousand years, the assertion, if incapable of proof, would be at least equally incapable of being _dis_-proven. But when the Lamarckian affirms that all our recent species of plants and animals were developed out of previously existing plants and animals of species entirely different, he affirms what, if true, _would_ be capable of proof; and so, if it cannot be proven, it is only because it is not true. The trilobites have been extinct ever since the times of the Mountain Limestone; and yet, by series of specimens, the individual development of certain species of this family, almost from the extrusion of the animal from the egg until the attainment of its full size, has been satisfactorily shown. By specimen after specimen has every stage of growth and every degree of development been exemplified; and the Palæontologist has come as thoroughly to know the creatures, in consequence, under their various changes from youth to age, as if they had been his contemporaries, and had grown up under his eye. And had our existing species, vegetable and animal, been derived from other species of the earlier periods, it would have been equally possible to demonstrate, by a series of specimens, _their_ relationship. Let us again instance the British shells. Losing certain species in each of the older and yet older deposits at which we successively arrive, we at length reach the Red and Coraline Crags, where we find, mingled with the familiar forms, a large per centage of forms now extinct; then going on to the shells of the lower Miocene, more than six hundred species appear, almost all of which are strange to us; and then, passing to the Eocene shells of the _Calcaire grossier_, we find ourselves among well nigh as large a group of yet other and older strangers, not one of which we are able to identify with any shell now living in the British area. There would be thus no lack of materials for forming such a genealogy of the British shells, had they been gradually developed out of the extinct species, as that which M. Barrande has formed of the trilobites. But no such genealogy can be formed. We cannot link on a single recent shell to a single extinct one. _Up_ to a certain point we find the recent shells exhibiting all their present specific peculiarities, and beyond that point they cease to appear. _Down_ to a certain point the extinct shells also exhibit all _their_ specific peculiarities, and then they disappear forever. There are no intermediate species,--no connecting links,--no such connected series of specimens to be found as enables us to trace a trilobite through all its metamorphoses from youth to age. All geologic history is full of the beginnings and the ends of species,--of their first and their last days; but it exhibits no genealogies of development. The Lamarckian sets himself to grapple, in his dream, with the history of all creation: we awaken him, and ask him to grapple, instead, with the history of but a few individual species,--with that of the mussel or the whelk, the clam or the oyster; and we find from his helpless ignorance and incapacity what a mere pretender he is. But while no hypothesis of development can neutralize or explain away the great geologic fact, that every true species had a beginning independently, apparently, of every preceding species, there was demonstrably a general progress, in the course of creation, from lower to higher forms, which seems scarce less fraught with important consequences to the natural theologian than this fact of _beginning_ itself. For while the one fact effectually disposes of the "infinite series" of the atheist, the other fact disposes scarce less effectually of those reasonings on the skeptical side which, framed on the assumption that creation is a "singular effect,"--an effect without duplicate,--have been employed in urging, that from that one effect only can we know aught regarding the producing cause. Knowing of the cause from but the effect, and having experience of but one effect, we cannot rationally hold, it has been argued, that the producing cause could have originated effects of a higher or more perfect kind. The creation which it produced we know; but, having no other measure of its power, we cannot regard it, it has been contended, as equal to the production of a better or nobler creation, or of course hold that it _could_ originate such a state of things as that perfect future state which faith delights to contemplate. It has been well said of the author of this ingenious argument,--by far the most sagacious of the skeptics,--that if we admit his premises we shall find it difficult indeed to set aside his conclusions. And how, in this case, does geology deal with his premises? By opening to us the history of the remote past of our planet, and introducing us, through the present, to former creations, it breaks down that _singularity_ of effect on which he built, and for one creation gives us many. It gives us exactly that which, as he truly argued, his contemporaries had not,--an _experience_ in creations. And let us mark how, applied to each of these in succession, his argument would tell. There was a time when life, animal or vegetable, did not exist on our planet, and when all creation, from its centre to its circumference, was but a creation of dead matter. What, in that early age, would have been the effect of the argument of Hume? Simply this,--that though the producing Cause of all that appeared was competent to the formation of gases and earths, metals and minerals, it would be unphilosophic to deem him adequate to the origination of a single plant or animal, even to that of a spore or of a monad. Ages pass by, and the Palæozoic creation is ushered in, with its tall araucarians and pines, its highly organized fishes, and its reptiles of comparatively low standing. And how now, and with what effect, does the argument apply? It is now rendered evident, that in the earlier creation the producing Cause had exerted but a portion of his power, and that he could have done greatly more than he actually did, seeing that we now find him adequate to the origination of vitality and organization in its two great kingdoms, plant and animal. But, still confining ourselves with cautious skepticism within the limits of our argument, we continue to hold that, as fishes of a high and reptiles of a low order, with trees of the cone-bearing family, are the most perfect specimens of their respective classes which the producing Cause has originated, it would be rash to hold, in the absence of proof, that he _could_ originate aught higher or more perfect. And now, as yet other ages pass away, the creation of the great Secondary division takes the place of that of the vanished Palæozoic; and we find in its few dicotyledonous plants, in its reptiles of highest standing, in its great birds, and in its some two or three humble marsupial mammals, that in the previous, as in the earlier creation, the producing Cause had been, if I may so express myself, working greatly under his strength, and that in this third creation we have a still higher display of his potency. With some misgivings, however, we again apply our argument. And now yet another creation,--that of the Tertiary period, with its noble forests of dicotyledonous trees and its sagacious and gigantic mammals,--rises upon the scene; and as our experience in creations has now become very considerable, and as we have seen each in succession higher than that which preceded it, we find that, notwithstanding our assumed skepticism, we had, compelled by one of the most deeply seated instincts of our nature, been secretly anticipating the advance which the new state of things actually realizes. But applying the argument once more, we at least assume to hold, that as the sagacious elephant is the highest example of animal life yet produced by the originating Cause, it would be unphilosophic to deem him capable of producing a higher example. And, while we are thus reasoning, man appears upon creation,--a creature immeasurably superior to all the others, and whose very nature it is to make use of his experience of the past for his guidance in the future. And if that only be solid experience or just reasoning which enables us truly to anticipate the events which are to come, and so to make provision for them; and if that experience be not solid, and that reasoning not just, which would serve but to darken our discernment, and prevent us from correctly predicating the cast and complexion of coming events; what ought to be our decision regarding an argument which, had it been employed in each of the vanished creations of the past, would have had but the effect of arresting all just anticipation regarding the immediately succeeding creation, and which, thus reversing the main end and object of philosophy, would render the philosopher who clung to it less sagacious in divining the future than even the ordinary man? But, in truth, the existing premises, wholly altered by geologic science, are no longer those of Hume. The footprint on the sand--to refer to his happy illustration--does not now stand alone. Instead of one, we see many footprints, each in turn in advance of the print behind it, and on a higher level; and, founding at once on an acquaintance with the past, extended throughout all the periods of the geologist, and on that instinct of our nature whose peculiar function it is to anticipate at least one creation more, we must regard the expectation of "new heavens and a new earth, wherein dwelleth righteousness," as not unphilosophic, but as, on the contrary, altogether rational and according to experience. Such is the bearing of geological science on two of the most important questions that have yet been raised in the field of natural theology. Nor does it bear much less directly on a controversy to which, during the earlier half of the last century, there was no little importance attached in Britain, and which engaged on its opposite sides some of the finest and most vigorous intellects of the age and country. The school of infidelity represented by Bolingbroke, and, in at least his earlier writings, by Soame Jenyns, and which, in a modified form, attained to much popularity through Pope's famous "Essay," assigned to man a comparatively inconsiderable space in the system of the universe. It regarded him as but a single link in a chain of mutual dependency,--a chain which would be no longer an entire, but a broken one, were he to be struck out of it, but as thus more important from his position than from his nature or his powers. You will remember that one of the sections of Pope's first epistle to his "good St. John" is avowedly devoted to show what he terms the "absurdity of man's supposing himself the final cause of the creation;" and though this great master of condensed meaning and brilliant point is now less read than he was in the days of our grandfathers, you will all remember the elegant stanzas in which he states the usual claims of the species only to ridicule them. It is human pride personified that he represents as exclaiming,-- "For me kind Nature wakes her genial power, Suckles each herb, and spreads out every flower, Annual for me the grape, the rose, renew The juice nectarious and the balmy dew. For me the mine a thousand treasures brings; For me health gushes from a thousand springs; Seas roll to waft me, suns to light me rise; My footstool earth, my canopy the skies." You will further remember how the poet, after thus reducing the claims and lowering the position of the species, set himself to show that man, viewed in relation to the place which he occupies, ought not to be regarded as an imperfect being. Man is, he said, as perfect as he ought to be. And, such being the case, the Author of all, looking, it would seem, very little after him, has just left him to take care of himself. A cold, unfeeling abstraction, like the gods of the old Epicurean, the Great First Cause of this school is a being "Who sees with equal eye, as God of all, A hero perish or a sparrow fall; Atoms or systems into ruin hurled, And now a bubble burst, and now a world." Such, assuredly, was not that God of the New Testament whom the Saviour of mankind revealed to his disciples as caring for all his creatures of the dust, but as caring most for the highest of all. "Are not two sparrows," he said, "sold for a farthing? and one of them shall not fall to the ground without your Father. Fear ye not, therefore; ye are of more value than many sparrows." It was the error of this ingenious but very unsolid school, that it regarded the mere _order_ of the universe as itself an end or final cause. It reasoned respecting creation, as if it would be true philosophy to account for the origin and existence of some great city, such as the city of Washington in the United States, built, as we know, for purely political purposes, by showing that,--as it was remarkable for its order, for the rectilinear directness of its streets, and the rectangularity of its squares,--it must have been erected simply to be a perfect embodiment of regularity; and to urge further that, save in their character as component parts of a perfect whole, the House of Representatives and the mansion of the President were of no more intrinsic importance, or no more decidedly the _end_ of the whole, than any low tavern or outhouse in the lesser streets or lanes. The destruction of either the outhouse or the House of Representatives would equally form a void in the general plan of the city, regarded as an admirably arranged whole. And it was thus with the grand scheme of creation; for, "From nature's chain whatever link we strike, Tenth or tenth thousand, breaks the chain alike." Nor is it in other than due keeping with such a view of creation, that its great Author should be represented as a cold abstraction, without love or regard, and equally indifferent to the man and the sparrow, to the atom and the planet. Order has respect to but the _relations_ of things or of beings,--not to the things or beings themselves; order is the _figure_ which, as mere etched points or strokes, they compose,--the legend which, as signs or characters, they form; and who cares anything for the component strokes or dots irrespective of the print, or for the component letters or words apart from the writing? The "equal eye," in such a scheme, would of necessity be an indifferent one. Against this strange doctrine, though in some measure countenanced by the glosses of Warburton in his defence of Pope, the theologians protested,--none of them, however, more vigorously than Johnson, in his famous critique on the "Free Inquiry" of Soame Jenyns. Nor is it uninteresting to mark with what a purely instinctive feeling of the right some of the better poets, whose "lyre," according to Cowper, was their "heart," protested against it too. Poor Goldsmith, when sitting a homeless vagabond on the slopes of the Alps, could exclaim in a greatly truer tone than that of his polished predecessor,-- "Creation's heir, the world, the world is mine!" And in Cowper himself we find all Goldsmith's intense feeling of appropriation, that "calls the delightful scenery all its own," associated "With worthy thoughts of that unvaried love That planned, and built, and still upholds, a world So clothed with beauty, for rebellious man." Strange to say, however, it is to the higher exponents of natural science, and in especial to the geologists, that it has been left to deal most directly with the sophistries of Bolingbroke and Pope. Oken, a man quite as far wrong in some points as either the poet or his master, was the first to remark, and this in the oracular, enigmatical style peculiar to the German, that "man is the sum total of all the animals." Gifted, as all allow, with a peculiarly nice eye for detecting those analogies which unite the animal world into a harmonious whole, he remarked, that in one existence or being all these analogies converge. Even the humbler students of the heavens have learned to find for themselves the star of the pole, by following the direction indicated by what are termed the two pointer stars in the Great Bear. And to the eye of Oken all the groups of the animal kingdom formed a sphere of constellations, each of which has its pointer stars, if I may so speak, turned towards man. Man occupies, as it were, the central point in the great circle of being; so that those lines which pass singly through each of the inferior animals stationed at its circumference, meet in him; and thus, as the focus in which the scattered rays unite, he imparts by his presence a unity and completeness to creation which it would not possess were he away. You will be startled, however, by the language in which the German embodies his view; though it may be not uninstructive to refer to it in evidence of the fact that a man may be _intellectually_ on the very verge of truth, and yet for every moral purpose infinitely removed from it. "Man," he says, "is God manifest in the flesh." And yet it may be admitted that there is a certain loose sense in which man _is_ "God manifest in the flesh." As may be afterwards shown, he is God's _image_ manifested in the flesh; and an image or likeness _is_ a manifestation or making evident of that which it represents, whether it be an image or likeness of body or of mind. Not less extraordinary, but greatly more sound in their application, are the views of Professor Owen,--supreme in his own special walk as a comparative anatomist. We find him recognizing man as exemplifying in his structure the perfection of that type in which, from the earliest ages, nature had been working with reference to some future development, and as _therefore_ a foreordained existence. "The recognition of an ideal exemplar for the vertebrated animals proves," he says, "that the knowledge of such a being as man must have existed before man appeared. For the Divine mind that planned the archetype also foreknew all its modifications. The archetypal idea was manifested in the flesh under divers modifications, upon this planet, long prior to the existence of those animal species that actually exemplify it." So far Owen. And not less wonderful is the conclusion at which Agassiz has arrived, after a survey of the geologic existences, more extended and minute, in at least the ichthyic department, than that of any other man. "It is evident," we find him saying, in the conclusion of his recent work, "The Principles of Zoology,"[20] "that there is a manifest progress in the succession of beings on the surface of the earth. This progress consists in an increasing similarity to the living fauna, and among the vertebrates, especially in their increasing resemblance to man. But this connection is not the consequence of a direct lineage between the faunas of different ages. There is nothing like parental descent connecting them. The fishes of the Palæozoic age are in no respect the ancestors of the reptiles of the Secondary age, nor does man descend from the mammals which preceded him in the Tertiary age. The link by which they are connected is of a higher and immaterial nature; and their connection is to be sought in the view of the Creator himself, whose aim in forming the earth, in allowing it to undergo the successive changes which geology has pointed out, and in creating successively all the different types of animals which have passed away, _was to introduce man upon the surface of our globe_. MAN IS THE END TOWARDS WHICH ALL THE ANIMAL CREATION HAS TENDED FROM THE FIRST APPEARANCE OF THE FIRST PALÆOZOIC FISHES." These, surely, are extraordinary deductions. "In thy book," says the Psalmist, "all my members were written, which in continuance were fashioned when as yet there was none of them." And here is natural science, by the voice of two of its most distinguished professors, saying exactly the same thing. Of the earliest known vertebrates,--the placoidal fishes of the Upper Silurian rocks,--we possess only fragments, which, however, sufficiently indicate, from their resemblance to the corresponding parts of an existing shark,--the cestracion,--that they belonged to fishes furnished with the two pairs of fins now so generally recognized as the homologues of the fore and hinder limbs in quadrupeds. With the second earliest vertebrates,--the ganoids of the Old Red Sandstone,--we are more directly acquainted, and know that they exhibited the true typical form,--a vertebral column terminating in a brain-protecting skull; and that, in at least the acanth, celacanth, and dipterian families, they had the limb-like fins. In the upper parts of the system the earliest reptiles leave the first known traces of the typical foot, with its five digits. Higher still in one of the deposits of the Trias we are startled by what seems to be the impression of a human hand of an uncouth massive shape, but with the thumb apparently set in opposition, as in man, to the other fingers; we next trace the type upwards among the wonderfully developed reptiles of the Secondary periods; then among the mammals of the Tertiary ages, higher and yet higher forms appear; the mute prophecies of the coming being become with each approach clearer, fuller, more expressive, and at length receive their fulfilment in the advent of man. A double meaning attaches to the term type; and hence some ambiguity in the writings which have appeared on this curious subject. Type means a prophecy embodied in symbol; it means also what Sir Joshua Reynolds well terms "one of the general forms of nature,"--a pattern form, from which all others in the same class or family, however numerous, are recognized as mere exceptions and aberrations. But in the geologic series both meanings converge and become one. The form or number typical as the _general_ form or number, is found typical also as a _prophecy_ of the form or number that came at length to be exemplified in the deputed lord of creation. Let us in our examples take typical numbers, as more easily illustrated without diagrams than typical forms. There are vertebrate animals of the second age of ichthyic existence, that, like the _Pterichthys_ and _Coccosteus_, were furnished with but two limbs. The murænidæ of recent times have no more; at least one of their number, the muræna proper, wants limbs altogether; so also do the lampreys. The snakes are equally limbless, save that the boas and pythons possess the rudiments of a single pair; and such also is the condition, among the amphibia, of all the known species of Coecilia. And yet, notwithstanding these exceptional cases, the true typical number of limbs, as shown by a preponderating majority of the vertebrates of all ages of the world, is four. And this typical number is the human number. There is as certainly a typical number of digits too, as of the limbs which bear them. The exceptions are many. All the species of the horse genus possess but a single digit; the cattle family possess but two digits, the rhinoceros three digits, the hippopotamus four digits; many animals, such as the dog and cat, have but four digits on one pair of limbs and five on the other; whereas in some of the fishes the number of digits is singularly great,--from ten to twenty in most species, and in the rays from eighty to a hundred. And yet, as shown in the rocks, in which, however, the aberrations appear early, the true typical number is five on both the fore and hinder limbs. And such is the number in man. There is also, in at least the mammalia, a typical number of vertebræ in the neck. The three-toed sloth has nine cervical vertebræ; the manati only six; but seven is the typical number. And seven is the human number also. Man, in short, is pre-eminently what a theologian would term the antetypical existence,--the being in whom the types meet and are fulfilled. And not only do typical forms and numbers of the exemplified character meet in man, but there are not a few parts of his framework which in the inferior animals exist as but mere symbols, of as little importance as dugs in the male animal, though they acquire significancy and use in him. Such, for instance, are the many-jointed but moveless and unnecessary bones of which the stiff inflexible _fin_ of the dugong and the fore paw of the mole consist, and which exist in his arm as essential portions, none of which could be wanted, of an exquisitely flexible instrument. In other cases, the old types are exemplified serially in the growth and development of certain portions of his frame. Such is specially the case with that all important portion of it, the organ of thought and feeling. The human brain is built up by a wonderful process, during which it assumes in succession the form of the brain of a fish, of a reptile, of a bird, of a mammiferous quadruped; and, finally, it takes upon it its unique character as a human brain. Hence the remark of Oken, that "man is the sum total of all the animals;" hence, too, a recognition of type in the _history_ of the successive vertebral periods of the geologist, symbolical of the history of every individual man. It is not difficult to conceive how, on a subject of such complexity, especially if approached in an irreverent spirit, grave mistakes and misconceptions should take place. Virgil knew just enough of Hebrew prophecy to misapply, in his _Pollio_, to his great patron Octavius, those ancient predictions which foretold that in that age the Messiah was to appear. And I am inclined to hold, that in the more ingenious speculations of the Lamarckians we have just a similar misapplication of what, emboldened by the views of Owen and Agassiz, I shall venture to term the _Geologic Prophecies_. The term is new, but the idea which it embodies, though it at first existed rather as a nice poetic instinct than as a scientifically based thought, is at least as old as the times of Herder and Coleridge. In a passage quoted from the former writer by Dr. M'Cosh, in his very masterly work on typical forms, I find the profound German remarking of the strange resemblances which pervade all nature, and impart a general unity to its forms, that it would seem "as if on all our earth the form-abounding mother had proposed to herself but one type,--one proto-plasma,--according to which, and for which, she formed them all. Know, then," he continues, "what this form is. It is the identical one which man also wears." And the remark of Coleridge, in his "Aids to Reflection," is still more definite. "Let us carry us back in spirit," he says, "to the mysterious week, the teeming work days of the Creator (as _they rose in_ VISION _before the eye of the inspired historian_) of the operations of the heavens and of the earth, in the day that the Lord God made the earth and the heavens. And who that watched their ways with an understanding heart could, as the vision evolved still advanced towards him, contemplate the filial and loyal bee, the home-building, wedded, and divorceless swallow, and, above all, the manifoldly intelligent ant tribes, with their commonwealths and confederacies, their warriors and miners, the husband folk that fold in their tiny flocks on the honey leaf, and the virgin sister with the holy instincts of maternal love detached and in selfless purity, and not say in himself, Behold the shadow of approaching humanity, the sun rising from behind in the kindling morn of creation?" There is fancy here; but it is that sagacious fancy, vouchsafed to only the true poet, which has so often proved the pioneer of scientific discovery, and which is in reality more sober and truthful, in the midst of its apparent extravagance, than the gravest cogitations of ordinary men. It is surely no incredible thing, that He who, in the dispensations of the human period, spake by type and symbol, and who, when He walked the earth in the flesh, taught in parable and allegory, should have also spoken in the geologic ages by prophetic figures embodied in the form and structure of animals. Nay, what the poet imagined, though in a somewhat extreme form, the philosophers seem to be on the very eve of confirming. The foreknown "archetypal idea" of Owen,--"the immaterial link of connection" of all the past with all the present, which Agassiz resolves into the foreordained design of the Creator,--will be yet found, I cannot doubt, to translate themselves into one great general truth, namely, that the Palæozoic, Secondary, and Tertiary dispensations of creation were charged, like the patriarchal and Mosaic dispensations of grace, with the "shadows of better things to come." The advent of man simply as such was the great event prefigured during the old geologic ages. The advent of that Divine Man "who hath abolished death, and brought life and immortality to light," was the great event prefigured during the historic ages. It is these two grand events, equally portions of one sublime scheme, originated when God took counsel with himself in the depths of eternity, that bind together past, present, and future,--the geologic with the Patriarchal, the Mosaic, and the Christian ages, and all together with that new heavens and new earth, the last of many creations, in which there shall be "no more death nor curse, but the throne of God and the Lamb shall be in it, and his servants shall serve him." "There is absurdity," said Pope, "in man's conceiting himself the final cause of creation." Unless, however, man had the entire scheme of creation before him, with the further partially known scheme of which but a part constitutes the grand theme of revelation, how could he pronounce on the absurdity? The knowledge of the geologist ascends no higher than man. He sees all nature in the pre-Adamic past, pointing with prophetic finger towards him; and on even the argument of Hume,--just and solid within its proper limits,--he refuses to acquiesce in the unfounded inference of Pope. In order to prove the absurdity of "man's conceiting himself the final cause of creation," proof of an ulterior cause,--of a higher end and aim,--must he adduced; and of aught higher than man, the geologist, as such, knows nothing. The long vista opened up by his science closes with the deputed lord of creation,--with man as he at present exists; and when, casting himself full upon revelation, the vail is drawn aside, and an infinitely grander vista stretches out before him into the future, he sees man--no longer, however, the natural, but the Divine man--occupying what is at once its terminal point and its highest apex. Such are some of the bearings of geologic science on the science of natural theology. Geology has disposed effectually and forever of the oft-urged assumption of an infinite series; it deals as no other science could have dealt with the assertion of the skeptic, that creation is a "singular effect;" it casts a flood of unexpected light on the somewhat obsolete plausibilities of Bolingbroke and Jenyns, that exhibits their utterly unsolid character; yet further, it exhibits in a new aspect the argument founded on design, and invests the place and standing of man in _creation_ with a peculiar significancy and importance, from its relation to the future. But on this latter part of my subject--necessarily of considerable extent and multiplicity, and connected rather with revealed than with natural religion--I must not now expatiate. I shall, however, attempt laying before you, on some future evening, a few thoughts on this portion of the general question, which you may at least find suggestive of others, and which, if they fail to elicit new truths, may have the effect of opening up upon an old truth or two a few fresh avenues through which to survey them. The character of man as a fellow-worker with his Creator in the material province has still to be considered in the light of geology. Man was the first, and is still the only creature of whom we know anything, who has set himself to carry on and improve the work of the world's original framer,--who is a planter of woods, a tiller of fields, and a keeper of gardens,--and who carries on his work of mechanical contrivance on obviously the same principles as those on which the Divine designer wrought of old, and on which he works still. It may not be wholly unprofitable to acquaint ourselves, through evidence furnished by the rocks, with the remarkable fact, that the Creator imparted to man the Divine image before he united to man's the Divine nature. LECTURE SIXTH. GEOLOGY IN ITS BEARINGS ON THE TWO THEOLOGIES. PART II. Up till the introduction of man upon our planet, the humbler creatures, his predecessors, formed but mere figures in its various landscapes, and failed to alter or affect by their works the face of nature. They were conspicuous, not from what they _did_, but from what they _were_. At a very early period reefs of coral, the work of minute zoophytes, whitened the shallows of the ocean, or encircled with pale, ever broadening frames, solitary islands green with the shrubs and trees of extinct floras; but, though products of the animal world, they were not built up under the direction of even an instinctive intelligence, but were as entirely the results of a _vegetative_ process of mere growth as the forests or reed brakes of the old Carboniferous savannahs. At a later time an ant hill might be here and there descried, rearing its squat, brown pyramid amid the recesses of some Oolitic forest; or, in a period still more recent, the dam of the gigantic beaver might be seen extending its minute eye-like circlet of blue amid the windings of some bosky ravine of the Pliocene age; or existing as a little mound-skirted pond, with the rude half-submerged _cottage_ of the creature, its architect, rising beside it, on some rivulet of the Pleistocene. But how inconsiderable such works, compared with the wide extent of prospect in which they were included! How entirely inconspicuous rather, save when placed in the immediate foreground of the pictures into whose composition they entered! Not until the introduction of man upon earth do we find a creature whose works sensibly affect and modify the aspects of nature. But when man appears, how mighty the change which he effects! Immediately on his creation he takes under his care the vegetable productions of use and show: it becomes his business to keep and dress a garden. He next becomes a tiller of fields, then a planter of vineyards: here he cuts down great forests; there he rears extensive woods. He makes himself places of habitation; and busy cities spring up as the trophies of his diligence and skill. His labors, as they grow upon the waste, affect the appearance of vast continents; until at length, from many a hill-top and tall spire, scarce a rood of ground can be seen on which he has not built, or sown, or planted, or around which lie has not erected his walls or reared his hedges. Man, in this great department of industry, is what none of his predecessors upon the earth ever were,--"a fellow-worker" with the Creator. He is a mighty _improver_ of creation. We recognize that as improvement which adapts nature more thoroughly to man's own necessities and wants, and renders it more pleasing both to his sense of the æsthetic and to his more material senses also. He adds to the beauty of the flowers which he takes under his charge,--to the delicacy and fertility of the fruits; the seeds of the wild grasses become corn beneath his care; the green herbs grow great of root or bulb, or bulky and succulent of top and leaf; the wild produce of nature _sports_ under his hand; the rose and lily broaden their disks and multiply their petals; the harsh green crab swells out into a delicious golden-rinded apple, streaked with crimson; the productions of his kitchen garden, strangely metamorphosed to serve the uses of his table, bear forms unknown to nature; an occult law of change and development inherent to these organisms meets in him with the developing instinct and ability, and they are regenerated under his surveillance. Nor is his influence over many of the animals less marked. The habits which he imparts to the parents become _nature_, in his behalf, in their offspring. The dog acquires, under his tutelage, the virtues of fidelity to a master and affection to a friend. The ox and horse learn to assist him in the labors of the fields. The udders of the cow and goat distend beneath his care far beyond the size necessary in the wild state, and supply him with rich milk, and the other various products of the dairy. The fleece of the sheep becomes finer of texture and longer of fibre in his pens and folds; and even the indocile silkworm spins, in his sheltered conservatories, and among the mulberry trees which he has planted, a larger, and brighter, and more glistening cocoon. Man is the great creature-worker of the world,--its one created being, that, taking up the work of the adorable Creator, carries it on to higher results and nobler developments, and finds a field for his persevering ingenuity and skill in every province in which his Maker had expatiated before him. He is evidently--to adopt and modify the remark of Oken--God's image "manifest in the flesh." Surveyed from the special point of view furnished by this peculiar nature of man, unique in creation, all the past of our planet divides into two periods;--the period, inclusive of every age known to the geologist, during which only the Creator wrought; and the period during which man has wrought, and to which all human history belongs. In such a view we are presented with two sets of works,--those of the Creator-worker, and those of the creature-worker; and the vast fund of materials on which the natural theologian frames his arguments demonstrative of design or contrivance, assumes a new significancy and interest when employed as evidence that there exists a certain correspondence of nature and intellect between the two workers, human and Divine. The ability of accomplishing the same ends by the same means,--in other words, of thinking and acting in the same practical tract,--indicates a similarity, if not identity, of intellectual nature. In the Chinese centre of civilization, for instance, printing, gunpowder, the mariner's compass, with the various chemical and mechanical arts of elegant life, were originated without concert with the European centre of civilization, simply because in China, as in Europe, the same human faculties, prompted by the same tastes and necessities, had expatiated in the same tracts of invention, and had, as a consequence, educed the same results. I was much struck, when spending half an hour in a museum illustrative of the arts in China, by the identity of these with our own, especially in the purely mechanical departments; and again, when similarly employed in that apartment devoted, in the British Museum, to the domestic utensils of the ancient Egyptians. The identity of the more common contrivances which I witnessed, with familiar contrivances in our own country, I regarded as altogether as conclusive of an identity of mind in the individuals who had originated them, as if I had actually seen human creatures at work on them all. One class of productions showed me that the potter's wheel and the turning lathe had been known and employed as certainly in China and ancient Egypt as in Britain. Another, that their weaving processes must have been nearly the same. The Chinese know, for instance, as well as ourselves, that patterns can be delicately brought out,--as in the damasks,--without the assistance of color, simply by exposing silken or flaxen fibre at different angles to the light; and they have fallen, as their work shows, on the right methods of producing it. And the Egyptians anticipated us in even our most homely household contrivances. They even fermented their bread and trussed their fowls after the same fashion; and thus gave evidence, in these familiar matters, that they thought and contrived "after the manner of men." Now, in acquainting myself with the organisms of the geologic periods, I have been similarly but more deeply impressed by what I must be permitted to term the _human_ cast and character of the contrivances which they exemplified. Not only could I understand the principles on which they were constructed, but further, not a few of them had, I found, been actually introduced into works of human invention ages ere they were discovered in the rock. What the great Creator-worker had originated in the Palæozoic and Secondary periods, had been in after times originated by the little creature-worker, wholly unaware that his contrivance had been anticipated, and was but a repetition of a previously executed design. In the later geologic ages the organization of the various extinct animals so nearly resembled that of the animals which still live, that we may regard it as not inadequately represented by the illustrations of Paley. A few such exceptional contrivances appear among the mammals of the Tertiary as that formed by the huge pickaxe-like tusks of the Dinotherium, or a few such extraordinary modifications of the ordinary mammalian framework as that exhibited in the enormously massive pelvic arches and hinder limbs of the Mylodon and Megatherium. But not until we pass into the deposits of the Secondary period, and get among its cephalopoda, do we find a mechanism altogether unlike any with which we are acquainted among living organisms. As admirably shown by Buckland, the partitions which separate into chambers all the whorls of the ammonite except the outermost one, were exquisitely adapted to strengthen, by the tortuous windings of their outer edges, a shell which had to combine great lightness with great powers of resistance. Itself a continuous arch throughout, it was supported by a series of continuous arches inside, somewhat resembling in form the groined ribs of the Gothic roof, but which, unlike the ponderous stone work of the mediæval architects, were as light as they were strong. And to this combination of arches there was added, in the ribs and grooves of the shell, yet another element of strength,--that which has of late been introduced into iron roofs, which, by means of their corrugations,--ribs and grooves like those of the ammonite,--are made to span over wide spaces, without the support of beams or rafters. Still more recently, the same principle has been introduced into metallic boats, which, when corrugated, like the old ammonites, are found to be sufficiently strong to resist almost any degree of pressure without the wonted addition of an interior framework. Similar evidences of design appear in the other extinct molluscs peculiar to these geologic ages, such as the hamite and turrilite. The belemnite seems to have united the principle of the float to that of the sinker, as we see both united in some of our modern life boats, which are steadied on their keel by one principle, and preserved from foundering by the other; or as we find them united by the boy in his mimic smack, which he hollows out and decks, in order to render it sufficiently light, while at the same time he furnishes it with a keel of lead, in order to render it sufficiently steady. The old articulata abound in marks of ingenious mechanical contrivance. The trilobites were covered over back and head with the most exquisitely constructed plate armor: but as their abdomens seem to have been soft and defenceless, they had the ability of coiling themselves round on the approach of danger, plate moving on plate with the nicest adjustment, till the rim of the armed tail rested on that of the armed head, and the creature presented the appearance of a ball defended at every point. In some genera, as in Calymene, the tail consisted of jointed segments till its termination; in others, as in Illænus, there was a great caudal shield, that in size and form corresponded to the shield which covered the head; the segments of Calymene, from the flexibility of their joints, fitted close to the cerebral rim; while the same effect was produced in the inflexible shields, caudal and cephalic, of Illænus, by their exact correspondence, and the flexibility of the connecting rings, which enabled them to fit together like two equal-sized cymbals brought into contact at every point by the hand. Nor were the ancient crinoids less remarkable for the amount of nice contrivance which their structures exhibited, than the ancient molluscs or crustaceans. In their calyx-like bodies, consisting always of many parts, we find the principle of the arch introduced in almost every possible form and modification, and the utmost flexibility secured to their stony arms by the amazing number of the pieces of which they were composed, and the nice disposition of the joints. In the Pentacrinites of the Secondary period (see Fig. 97) an immense spread of arms, about a thousand in number, and composed of about a hundred thousand separate pieces, had all the flexibility, though formed of solid lime, of a _drift_ of nets, and yet were so nicely jointed, tooth fitting into tooth in all their numerous parts, and the whole so bound together by ligament, that, with all the flexibility, they had also all the toughness and tenacity, of pieces of thread network. Human ingenuity, with the same purposes to effect, that is, the sweeping of shoals of swimming animals into a central receptacle, would probably construct a somewhat similar machine; but it would take half a lifetime to execute one equally elaborate. [Illustration: Fig. 94. AMMONITES HUMPHRIESIANUS. (_Oolite._)] [Illustration: Fig. 95. ENCRINITES MONILIFORMIS. (_Trias._)] [Illustration: Fig. 96. CUPRESSOCRINUS CRASSUS.

(_Glyptolepis._) (_Old Red Sandstone._)] In carefully examining, for purposes of restoration, some of the earliest ganoidal fishes, I was not a little impressed by the peculiar mechanical contrivances exhibited in their largely developed dermal skeletons. In some cases these contrivances were sufficiently simple, resembling those which we find exemplified in the humbler trades, originated in comparatively unenlightened ages; and yet their simplicity had but the effect of rendering the peculiarly _human_ cast of the mind exhibited in their production all the more obvious. The bony scales which covered fishes such as the Osteolepis and Diplopterus of the Old Red Sandstone, or the Megalichthys of the Coal Measures, were of considerable mass and thickness. They could not, compatibly with much nicety of finish, be laid over each other, like the thin horny scales of the salmon or herring; and so we find them curiously fitted together, not like slates on a modern roof, but like hewn stones on an ancient one. There ran on the upper surface of each, along the anterior side and higher end, a groove of a depth equal to half the thickness of the scale; and along the posterior side and lower end, on the under surface, a sort of bevelled chamfer, which, fitting into the grooves of the scales immediately behind and beneath it, brought their surfaces to the same line, and rendered the shining coverings of these strongly armed ganoids as smooth and even as those of the most delicately coated fishes of the present day. In the scales of the Celacanth family the arrangement was different. Though exceedingly massive in some of the genera, they were imbricated, like those of the Pangolins; and were chiefly remarkable for the combination of contrivances which they exhibited for securing the greatest possible amount of strength from the least possible amount of thickness. The scales of _Holoptychius giganteus_ may be selected as representative of those of the family to which it belonged. It consisted of three plates, or rather, like the human skull, of two solid plates, with a _diploe_ or spongy layer between. The outer surface was curiously fretted into alternate ridges and furrows; and hence the name of the genus,--_wrinkled scale_; and these imparted to the exterior plate on which they occurred, and which was formed of solid bone, the strength which results from a corrugated or fluted surface. Cromwell, in commissioning a friend to send him a helmet, shrewdly stipulated that it should be a "fluted pot;" and we find that the Holoptychius had got the principle of the fluted pot exemplified in the outer plate of each of its scales, untold ages before. The spongy middle plate must, like the diploe of the skull, have served to deaden the vibrations of a blow dealt from the outside. It was a stratum of sand bags piled up in the middle of a plank rampart. Their innermost table was formed, like the outer, of solid bone, but had a different arrangement. It was properly not one, but several tables, in each of which the osseous fibres, spread out in the general plane of the scale, lay at a diverse angle from those of the table immediately in contact with it. The principle was evidently that of the double-woven cloth, or cloth of two incorporated layers, such as _moleskin_, in which, from the arrangement of the threads, what a draper would term the _tear_ of the one layer or fold lies at a different angle in the general fabric from that of the other. We are thus presented, in a single fossil scale little more than the eighth part of an inch in thickness, with three distinct strengthening principles,--the principle of Cromwell's "fluted pot,"--the principle of a rampart lined with plank, and filled with sand bags in the centre,--and the principle of the double-woven fabrics of the "moleskin" manufacturer.[22] The contrivances exemplified in the cuirass of the Pterichthys were scarce less remarkable. It was formed of bony plates, strongly arched above, but comparatively flat beneath; and along both its anterior and posterior rims a sudden thickening of the plates formed a massive band, which served to strengthen the entire structure, as transverse ribs of stone are found strengthening Gothic vaults of the Norman age. The scale covered tail of the creature issued from within the posterior rim, which formed around it a complete though irregular ring, arched above and depressed beneath; whereas the anterior rim, to which the head was attached, was incomplete when separated from it. It was, in its detached state, an arch wanting the keystone. A keystone, however, projected outwards from the occipital plate of the head; and, as it had to form at once the bond of connection between the cerebral armature of the creature and its cuirass, and to complete the arch formed by the strengthening belt or rib of the latter, it curiously combined the principle of both the dovetail of the carpenter and the keystone of the mason. Viewed from above, it was a dovetail, forming a strong attachment of the head to the body; viewed in the transverse section, it was an efficient keystone, that gave solidity and strength to the arched belt or rib. Both keystone and dovetail are comparatively simple contrivances; but I know not that they have been united in the same piece, save in the very ancient instance furnished by the strong bony plate which connected the helmet of the Pterichthys with its cuirass. [Illustration: Fig. 99. SCALE OF HOLOPTYCHIUS GIGANTEUS. (Nat. size.) (_Old Red Sandstone._)] [Illustration: Fig. 100. SECTION OF SCALE OF HOLOPTYCHIUS. (Mag. eight diameters.)] A brief anecdote, yet further illustrative of the framework of this ancient ganoid, may throw some additional light on what I have ventured to term the _human_ cast of the contrivances exhibited in the organisms of the old geologic ages. After carefully examining many specimens, I published a restoration of both the upper and under side of Pterichthys fully fifteen years ago. The greatest of living ichthyologists, however, misled by a series of specimens much less complete than mine, differed from me in my conclusions; and what I had represented as the creature's under or abdominal side, he represented as its upper or dorsal side; while its actual upper side he regarded as belonging to another, though closely allied, genus. I had no opportunity, as he resided on the Continent at the time, of submitting to him the specimens on which I had founded; though, at once certain of his thorough candor and love of truth, and of the solidity of my data, I felt confident that, in order to alter his decision, it was but necessary that I should submit to him my evidence. Meanwhile, however, the case was regarded as settled against me; and I found at least one popular and very ingenious writer on geology, after referring to my description of the Pterichthys, going on to say that, though graphic, it was not correct, and that he himself could describe it at least more truthfully, if not more vividly, than I had done. And then there followed a description identical with that by which mine had been supplanted. Five years had passed, when one day our greatest British authority on fossil fishes, Sir Philip Egerton, was struck, when passing an hour among the ichthyic organisms of his princely collection, by the appearance presented by a central plate in the cuirass of the Pterichthys. It is of a lozenge form, and, occupying exactly such a place in the nether armature of the creature as that occupied by the lozenge shaped spot on the ace of diamonds, it comes in contact with four other plates that lie around it, and represent, so to speak, the white portions of the card. And Sir Philip now found, that instead of lying over, it lay under, the four contiguous plates: they overlapped it, instead of being overlapped by it. This, he at once said, on ascertaining the fact, cannot be the _upper_ side of the Pterichthys. A plate so arranged would have formed no proper protection to the exposed dorsal surface of the creature's body, as a slight blow would have at once sent it in upon the interior framework; but a proper enough one to the under side of a heavy swimmer, that, like the flat fishes, kept close to the bottom;--a character which, as shown by the massive bulk of its body, and its small spread of fin, must have belonged to the Pterichthys. Sir Philip followed up his observations on the central plate by a minute examination of the other parts of the creature's armature; and the survey terminated in a recognition of the earlier restoration,--set aside so long before,--as virtually the true one;--a recognition in which Agassiz, when made acquainted with the nature of the evidence, at once acquiesced. Now, here was there a question which had been raised regarding the true mechanism of one of the oldest ganoidal fishes, and settled erroneously on wrong data, again opened up, to be settled anew on one of the most obvious mechanical principles exemplified in the simple art of the slater or tiler. The argument of Sir Philip amounted simply to this:--If the accepted restoration be a true one, then the Creator of the Pterichthys must have committed a mistake in mechanics which an ordinary slater would have avoided; but as the Creator commits no such blunders, the mistake probably occurs in but the restoration. I may mention, that the dorsal surface of this ancient fish had also its central plate,--a lozenge truncated at its two longer ends; and that, moulded to meet the necessities of its position, it was not flat, like the under one, but strongly arched; and that on four of its six sides it overrode by a squamose suture the lower plates with which it came in contact. These are but humble illustrations of the designing principle, as exhibited of old; and yet they impress none the less strongly on that account. Among the many contrivances of the Chinese Museum, to which I have already referred, none seemed more to excite the curiosity of visitors than a set of tall-backed, elaborately carved chairs, exceedingly like those which were used in our own country two centuries ago, and which Cowper so exquisitely describes. For thousands of miles in the wide tract that spreads out between European Christendom and the great wall, the inhabitants squat upon mats or carpets, or loll on divans; and the contrivance of the chair is unknown: it reappears in China, however, and reappears, not as a mere seat or stool, but as, in every bar and limb, the identical chair of Europe arrested a century or two back in its development. And every corresponding tenon and mortise exhibited by the Chinese and European examples of this simple piece of furniture served more forcibly to show an identity of character in the minds which had originated them in countries so far apart, than the more elaborate contrivances which, though illustrative of the same principles of invention, were less easily understood. It is so with the more simple and familiar instances of adaptation furnished by the works of the Creator. We infer from them, more directly than from the complex mechanisms, that he who wrought of old after the manner of a man must have, in his intellectual character, if I may so express myself, certain man-like qualities and traits. In all those works on Natural Theology that treat, like the work of Paley, on the argument of design, the assumption of a certain unity of the intellectual nature of the Creator and creature is made, tacitly at least, the basis of all the reasonings; and it is in the cases in which the design is most simple that the argument is most generally understood. It is in the lower _skirts_ of the Divine nature that we most readily trace the resemblance to the nature of man,--an effect, mayhap, of the narrow reach of our faculties in their present infantile state. [Illustration: Fig. 101. SIGILLARIA GROESERI (_Coal Measures._)] [Illustration: Fig. 102. Fig. 103. Fig. 104. WHORLED SHELLS OF THE OLD RED SANDSTONE.[23]] But the resemblance is not restricted to the constructive department. Both in the Chinese collection and among the Egyptian antiquities exhibited in the British Museum, I found color as certainly as mechanical contrivance. And the color furnished not only a practical example from both the early and the remote peoples of the same sort of chemical science as exists at the present time among ourselves in our dyeworks and pigment manufactories, but it also showed a certain identity with our own of their sense of beauty. The Chinese satins are gorgeous with green, blue, yellow, scarlet, crimson, and purple, and have fringes heavy with thread of gold. Gilding is as common among this distant people as among ourselves, and at once shows a familiarity with the art of the gold beater, and a sensibility to the beauty of a golden surface; and in the painted ornaments I detected the rich tints of vermilion and crimson lake, with the mineral blues, yellows, and greens. In the Egyptian department, though the blanching influences of three thousand years had dimmed the tints and tarnished the metals, I found evidence of the same regard to hue and lustre as exists still in China and among ourselves; all that now pleases the eye in London and Pekin had pleased it in Thebes during the times of the earlier Pharaohs. And just as we infer from the mechanical contrivances of the Creative-Worker that he possesses a certain identity of mind in the _constructive_ department with his creature-workers, and this upon the principle on which we infer an identity of mind between the creature-workers of China, ancient Egypt, and our own country, seeing that their works are identical, must we not also infer, on the same principle, that he possesses in the _æsthetic_ department a certain identity with them also. True, this region of the beautiful, ever surrounded by an atmosphere of obscure, ill-settled metaphysics, is greatly less clear than that mechanical province of whose various machines, whether of Divine or human contrivance, it can be at least affirmed that machines they _are_, and that they effect their purposes by contrivances of the same or of resembling kinds. And yet the appearance in nature, age after age, of the same forms and colors of beauty which man, in gratifying his taste for the lovely in shape and hue, is ever reproducing for himself, does seem to justify our inference of an identity of mind in this province also. The colors of the old geologic organisms, like those of the paintings of ancient Egypt, are greatly faded. A few, however, of the Secondary, and even Palæozoic shells, still retain the rich prismatic hues of the original nacre. Many of the Tertiary division still bear the distinctive painted spots. Some of the later fossil fishes, when first laid open in the rock, exhibit the pearly gleam that must of old have lighted up the green depths of the water as they darted through. Not a few of the fossil corals preserve enough of their former color to impart much delicacy of tint to the marbles in which they occur. But it is chiefly in form, not in shade or hue, that we find in the organisms of the geologic ages examples of that beauty in which man delights, and which he is ever reproducing for himself. There is scarce an architectural ornament of the Gothic or Grecian styles which may not be found existing as fossils in the rocks. The Ulodendron was sculptured into gracefully arranged rows of pointed and closely imbricated leaves, similar to those into which the Roman architects fretted the torus of the Corinthian order. The Sigillaria were fluted columns ornately carved in the line of the channelled flutes; the Lepidodendra bore, according to their species, sculptured scales, or lozenges, or egg-like hollows, set in a sort of frame, and relieved into knobs and furrows; all of them furnishing examples of a delicate diaper work, like that so admired in our more ornate Gothic buildings, such as Westminster Abbey, or Canterbury and Chichester Cathedrals, only greatly more exquisite in their design and finish. The scroll shells, a very numerous section of the class in the earlier ages, such as Maclurea, Euomphalus, Clymenia, and the great family of the ammonites, were volutes of varying proportions, but not less graceful than the ornament of similar proportions so frequently introduced into Greek and Roman architecture, and of which we have such prominent examples in the capitals of the Ionic, Corinthian, and composite orders. In what is known as the modern Ionic the spiral of the volute is not all on one plane; it is a Euomphalus: in the central volutes of the Corinthian the spiral is an open one; it is a Lituite or Gyroceras: in the ancient Ionic it is either wholly flat, as in Planorbus or the upper side of Maclurea, or slightly relieved, as in the ammonites. There is no form of the volute known to the architect which may not be found in the rocks, but there are many forms in the rocks unknown to the architect. Nor are the spire-like shells (see Fig. 105) less remarkable for the rich and varied style of their ornamentation than the whorled ones. They are spires, pinnacles, turrets, broaches; ornate, in some instances, beyond the reach of the architect, and illustrative, in almost all, of his happiest forms and proportions. We detect among the fossils the germs of numerous designs developed in almost every department of art; but merely to enumerate them would require a volume. One form of the old classic lamp was that of the nautilus; another, that of _Gyphæa incurva_; the zigzag mouldings of the Norman Gothic may be found in the carinated oysters of the Greensand; the more delicate frettings of similar form which roughened the pillars of a somewhat later age occur on Conularia and the dorsal spines of Gyracanthus. The old corals, too, abound in ornamental patterns, which man, unaware of their existence at the time, devised long after for himself. In an article on calico printing, which forms part of a recent history of Lancashire, there are a few of the patterns introduced, backed by the recommendation that they were the most successful ever tried. Of one of these, known as "Lane's Net," there sold a greater number of pieces than of any other pattern ever brought into the market. It led to many imitations; and one of the most popular of these answers line for line, save that it is more stiff and rectilinear, to the pattern in a recently discovered Old Red Sandstone coral, the _Smithia Pengellyi_. The beautifully arranged lines which so smit the dames of England, that each had to provide herself with a gown of the fabric which they adorned, had been stamped amid the rocks _eons_ of ages before. And it must not be forgotten, that all these forms and shades of beauty which once filled all nature, but of which only a few fragments, or a few faded tints, survive, were created, not to gratify man's love of the æsthetic, seeing that man had no existence until long after they had disappeared, but in meet harmony with the tastes and faculties of the Divine Worker, who had in his wisdom produced them all.

(_Manchester._)] [Illustration: Fig. 108. SMITHIA PENGELLYI. (_Old Red Sandstone._)] You will, I trust, bear with me should I seek, in depths where the light shed by science becomes obscure, to guide my steps by light derived from another and wholly different source. In an assembly such as that which I have now the honor of addressing, there must be many shades of religious opinion. I shall, however, assail no man's faith, but simply lay before you a few deductions which, founded on my own, have supplied me with what I deem a consistent theory of the curious class of phenomena with which this evening we have been mainly dealing. First, then, I must hold that we receive the true explanation of the _man_-like character of the Creator's workings ere man was, in the remarkable text in which we are told that "God made man in his own image and likeness." There is no restriction here to moral quality: the moral image man had, and in large measure lost; but the intellectual image he still retains. As a geometrician, as an arithmetician, as a chemist, as an astronomer,--in short, in all the departments of what are known as the strict sciences,--man differs from his Maker, not in kind, but in degree,--not as matter differs from mind, or darkness from light, but simply as a mere portion of space or time differs from _all_ space or _all_ time. I have already referred to mechanical contrivances as identically the same in the Divine and human productions; nor can I doubt that, not only in the pervading sense of the beautiful in form and color which it is our privilege as men in some degree to experience and possess, but also in that perception of harmony which constitutes the _musical_ sense, and in that poetic feeling of which Scripture furnishes us with at once the earliest and the highest examples, and which we may term the _poetic_ sense, we bear the stamp and impress of the Divine image. Now, if this be so, we must look upon the schemes of Creation, Revelation, and Providence, not as schemes of mere adaptation to man's nature, but as schemes also specially adapted to the nature of God as the pattern and original nature. Further, it speaks, I must hold, of the harmony and unity of one sublime scheme, that, after long ages of immaturity,--after the dynasties of the fish, the reptile, and the mammal should in succession have terminated,--man should have at length come upon the scene in the image of God; and that, at a still later period, God himself should have come upon the scene in the form of man; and that thus all God's workings in creation should be indissolubly linked to God himself, not by any such mere likeness or image of the Divinity as that which the first Adam bore, but by Divinity itself in the Second Adam; so that on the rainbow-encircled apex of the pyramid of created being the Son of God and the Son of Man should sit enthroned forever in one adorable person. That man should have been made in the image of God seems to have been a meet preparation for God's after assumption of the form of man. It was perhaps thus secured that _stock_ and _graft_, if I may venture on such a metaphor, should have the necessary affinity, and be capable of being united in a single person. The false gods of the Egyptians assumed, it was fabled, the forms of brutes: it was the human form and nature that was assumed by the true God;--so far as we know, the only form and nature that could have brought him into direct union with at once the matter and mind of the universe which he had created and made,--with "true body and reasonable soul." Yet further, I learn by inevitable inference from one of the more distinctive articles of my creed, that as certainly as the dynasty of the fish was predetermined in the scheme of Providence to be succeeded by the higher dynasty of the reptile, and that of the reptile by the still higher dynasty of the mammal, so it was equally predetermined that the dynasty of responsible, fallible man should be succeeded by the dynasty of glorified, immortal man; and that, in consequence, the present mixed state of things is not a mere result, as some theologians believe, of a certain human act which was perpetrated about six thousand years ago, but was, virtually at least, the effect of a God-determined decree, old as eternity,--a decree in which that act was written as a portion of the general programme. In looking abroad on that great history of life, of which the latter portions are recorded in the pages of revelation, and the earlier in the rocks, I feel my grasp of a doctrine first taught me by our Calvinistic Catechism at my mother's knee, tightening instead of relaxing. "The decrees of God are his eternal purposes," I was told, "according to the counsel of his will, whereby for his own glory he hath foreordained whatsoever comes to pass." And what I was told early I still believe. The programme of Creation and Providence, in all its successive periods, is of God, not of man. With the arrangements of the old geologic periods it is obvious man could have had nothing to do: the primeval ages of wondrous plants and monster animals ran their course without counsel taken of him; and in reading their record in the bowels of the earth, and in learning from their strange characters that such ages there were, and what they produced, we are the better enabled to appreciate the impressive directness of the sublime message to Job, when the "Lord answered him out of the whirlwind, and said, Where wast thou when I laid the foundations of the earth? Declare if thou hast understanding." And I can as little regard the present scene of things as an ultimate consequence of what man had willed or wrought, as even any of the pre-Adamic ages. It is simply one scene in a foreordained series,--a scene intermediate in place between the age of the irresponsible mammal and of glorified man; and to provide for the upward passage to the ultimate state, we know that, in reference to the purposes of the Eternal, he through whom the work of restoration has been effected was in reality what he is designated in the remarkable text, "The Lamb slain from the _foundations_ of the world." First in the course of things, man in the image of God, and next, in meet sequence, God in the form of man, have been equally from all eternity predetermined actors in the same great scheme. I approach a profound and terrible mystery. We can see how in the pre-Adamic ages higher should have succeeded lower dynasties. To be low was not to be immoral; to be low was not to be guilt-stained and miserable. The sea anemone on its half-tide rock, and the fern on its mossy hill-side, are low in their respective kingdoms; but they are, notwithstanding, worthy, in their quiet, unobtrusive beauty, of the God who formed them. It is only when the human period begins that we are startled and perplexed by the problem of a lowness not innocent,--an inferiority tantamount to moral deformity. In the period of responsibility, to be low means to be evil; and how, we ask, could a lowness and inferiority resolvable into moral evil have had any place in the decrees of that Judge who ever does what is right, and in whom moral evil can have no place? The subject is one which it seems not given to man thoroughly to comprehend. Permit me, however, to remark in reply, that in a sense so plain, so obvious, so unequivocally true, that it would lead an intelligent jury, impannelled in the case, conscientiously to convict, and a wise judge righteously to condemn, all that is evil in the present state of things man may as certainly have wrought out for himself, as the criminals whom we see sentenced at every justiciary court work out for themselves the course of punishment to which they are justly subjected. It has been well said of the Author of all by the poet, that, "binding nature fast in fate," he "left free the human will." And it is this freedom or independency of will operating on an intellect moulded after the image and likeness of the Divinity that has rendered men capable of being what the Scriptures so emphatically term "fellow-workers with God." In a humble and restricted sense, as I have already remarked,--humble and restricted, but in that restricted sense obviously true,--the surface of the earth far and wide testifies to this fact of fellowship in working. The deputed lord of creation, availing himself of God's natural laws, does what no mere animal of the old geologic ages ever did, or ever could have done,--he adorns and beautifies the earth, and adds tenfold to its original fertility and productiveness. In this special sense, then, he is a fellow-worker with Him who, according to the Psalmist, "causeth the grass to grow for the cattle, and herb for the service of man, and wine that maketh glad the heart of man, and oil that maketh his face to shine, and bread which strengtheneth man's heart." But it is in a greatly higher sense, and in reference to God's moral laws, that he is fitted to be his fellow-worker in the Scriptural sense. And his proper employment in this department is the elevation and development, moral and intellectual, of himself and his fellow-men, both in adaptation to the demands of the present time, and in preparation for a future state. All experience, however, serves to show that in this paramount department man greatly fails; nay, that he is infinitely less true to his proper end and destiny than the beasts that perish to their several instincts. And yet it may be remarked, that such of the lower animals as are guided by pure instinct are greatly more infallible within their proper spheres than the higher, half-reasoning animals. The mathematical bee never constructs a false angle; the sagacious dog is not unfrequently _out_ in his calculations. The higher the animal in the scale, the greater its liability to error. But it is not the less true, that no fish, no reptile, no mammal, of the geologic or the recent ages, ever so failed in working out the purposes it was created to serve, as man has failed in working out _his_; further, in no creature save in man does there exist that war of the mind between appetite and duty of which the Apostle so consciously complained. And we must seek an explanation of these twin facts in that original freedom of the will which, while it rendered man capable of being _of choice_ God's fellow-worker, also conferred on him an ability of choosing _not_ to work with God. And his choice of not working with him, or of working against him, being once freely made, we may see how, from man's very constitution and nature, as an intelligence united to matter that increases his kind from generation to generation in virtue of the original law, the ability of again working with God might be forever destroyed. And thus man's general condition as a lapsed creature may be as unequivocally a consequence of man's own act, as the condition of individuals born free, but doomed to slavery in punishment of their offences, is a consequence of _their_ own acts. A brief survey of the many-colored and variously-placed human family, as at present distributed on the earth, may enable us in some degree to conceive of a matter which, involving, as it does, that master problem of moral science, the origin of evil, seems, as I have said, not to be given to man fully to comprehend. "The different races of mankind," says Humboldt, employing, let me remark, the language of the distinguished German naturalist Müller, to give expression to the view which he himself adopts,--"the different races of mankind are not different species of a genus, but forms of one sole species." "The human species," says Cuvier, "appears to be single." "When we compare," says Pritchard, "all the facts and observations which have been heretofore fully established as to the specific instincts and separate psychical endowments of all the distinct tribes of sentient beings in the universe, we are entitled to draw confidently the conclusion, that all human races are of one species and one family." "God hath made of one blood," said the Apostle Paul, in addressing himself to the _élite_ of Athens, "all nations, for to dwell on the face of all the earth." Such, on this special head, is the testimony of Revelation, and such the conclusion of our highest scientific authorities. The question has, indeed, been raised in these latter times, whether each species of animals may not have been originally created, not by single pairs or in single centres, but by several pairs and in several centres, and, of course, the human species among the rest? And the _query_,--for in reality it amounts to nothing more,--has been favorably entertained on the other side of the Atlantic. On purely scientific grounds it is of course difficult to prove a negative in the case, just as it would be difficult to prove a negative were the question to be, whether the planet Venus was not composed of quartz rock, or the planet Mars of Old Red Sandstone? But the portion of the problem really solvable by science,--the identity of the human race under all its conditions, and in all its varieties,--science _has_ solved. It has determined that all the various tribes of man are but forms of a single species. And in the definition of species,--waiving the American _doubt_ until it shall at least become something more,--I am content to follow the higher authorities. "We unite," says M. de Candolle, "under the designation of a _species_, all those individuals that mutually bear to each other so close a resemblance as to allow of our supposing that they may have proceeded originally from a single being or a single pair." "A _species_," says Buffon, "is a constant succession of individuals similar to and capable of reproducing each other." "A _species_," says Cuvier, "is a succession of individuals which reproduces and perpetuates itself." Now, all history and all tradition, so far as they throw light on the question at all, agree in showing that the centre in which the human species originated must have been somewhere in the temperate regions of the East, not far distant from the Caucasian group of mountains. All the old seats of civilization,--that of Nineveh, Babylon, Palestine, Egypt, and Greece,--are spread out around this centre. And it is certainly a circumstance worthy of notice, and surely not without bearing on the _physical_ condition of primeval humanity, that in this centre we find a variety of the species which naturalists of the highest standing regard as fundamentally typical of the highest races of the globe. "The natives of the Caucasus," says Cuvier, "are even now considered as the handsomest on earth." And wherever man has, if I may so speak, _fallen_ least,--wherever he has retained, at least intellectually, the Divine image,--this Caucasian type of feature and figure, with, of course, certain national modifications, he also retains. It was developed in a remarkable degree among the old Greeks, as may be seen from the busts of some of their handsomer men; and still more remarkably in their _beau ideal_ of beauty, as exemplified in the statues of their gods. We see it also, though dashed with a shade of severity, in the strong forms and stern features of monarchs that reigned of old in Nineveh and Babylon, as brought to light in their impressive effigies by the excavations of Rawlinson and Layard. And further, though somewhat modified by the African dash, we detect it in the colossal statues of Egypt. Nor, as shown by Egyptian paintings still fresh in color and outline, was it less traceable in the ancient Jewish countenance and figure. It is still palpable, too, amid all the minor peculiarities of national physiognomy, in the various peoples of Europe. We may see it in our own country, though, as Sir Walter Scott truly tells us,-- "The rugged form may mark the mountain band, And harsher features and a mien more grave." It walks, however, the boards of our Parliament House here in a very respectable type of Caucasian man; and all agree that nowhere else in modern Europe is it to be found more true to its original contour than among the high-bred aristocracy of England, especially among the female members of the class. Looking, then, at the entire evidence,--at the admitted fact that the Circassians of the present day are an eminently handsome people,--that the old Greeks, Ninevites, Egyptians, Jews, Romans, and with these all the modern nations of Europe, are but the varieties of the central race that have retained in greatest perfection the original traits,--I do not see how we are to avoid the conclusion that this Caucasian type was the type of Adamic man. Adam, the father of mankind, was no squalid savage of doubtful humanity, but a noble specimen of man; and Eve a soft Circassian beauty, but exquisitely lovely beyond the lot of fallen humanity. "The loveliest pair That ever yet in love's embraces met: Adam, the goodliest man of men since born His sons; the fairest of her daughters Eve." I know not whether I should add what follows. It has been said that Luke, the "beloved physician," was also a painter. It has been said that that traditionary, time-honored form, which we at once recognize in the pictures of the old masters as that of the Saviour of mankind, he in reality bore when he walked this earth in the flesh. I know not what degree of probability attaches to the belief. I know not whether the traditionary form be in reality the true one. This, however, I know, that _if_ such was the form which the adorable Redeemer assumed when he took to himself a real body and a reasonable soul, the second Adam, like the first, exemplified, when upon earth, the perfect type of Caucasian man. Let me next remark, that the further we remove from the original centre of the race, the more degraded and sunk do we find the several varieties of humanity. We must set wholly aside, in our survey, the disturbing element of modern emigration. Caucasian man has been pressing outwards. In the backwoods of America, in Southern Africa, in Australia, and in the Polynesian islands, the old Adamic type has been asserting its superiority, and annihilating before it the degraded races. But taking into account merely the aboriginal varieties, it seems to be a general rule, that the further we remove in any direction from the Adamic centre, the more animalized and sunk do we find the various tribes or races. Contrary to the conceptions of the assertors of the development hypothesis, we ascertain, as we proceed outwards, that the course is not one of progression from the low to the high, but of descent from the high to the low. Passing northwards, we meet, where the lichen-covered land projects into the frozen ocean, with the diminutive Laps, squat, ungraceful, with their flat features surmounted by pyramidal skulls of small capacity, and, as a race, unfitted for the arts either of peace or war. We meet also with the timid Namollas, with noses so flat as to be scarce visible in the women and children of the race; and with the swarthy Kamtschatkans, with their broad faces, protuberant bellies, and thin, ill-formed legs. Passing southwards, we come to the negro tribes, with their sooty skins, broad noses, thick lips, projecting jawbones, and partially-webbed fingers. And then we find ourselves among the squalid Hottentots, repulsively ugly, and begrimmed with filth; or the still more miserable Bushmen. Passing eastwards, after taking leave of the Persian and Indian branches of the Caucasian race, we meet with the squat Mongolian, with his high cheek bones set on a broad face, and his compressed, unintellectual, pig-like eyes; or encounter, in the Indian Archipelago or the Australian interior, the pitiably low Alforian races, with their narrow, retreating foreheads, slim, feeble limbs, and baboon-like faces. Or, finally, passing westward, we find the large-jawed, copper-colored Indians of the New World, vigorous in some of the northern tribes as animals, though feeble as men, but gradually sinking in southern America, as among the wild Caribs or spotted Araucans; till at the extremity of the continent we find, naked and shivering among their snows, the hideous, small-eyed, small-limbed, flat-headed Fuegians, perhaps the most wretched of human creatures. And all these varieties of the species, in which we find humanity "fallen," according to the poet, "into disgrace," are varieties that have lapsed from the original Caucasian type. They are all the descendants of man as God created him; but they do not exemplify man as God created him. They do not represent, save in hideous caricature, the glorious creature moulded of old by the hand of the Divine Worker. They are fallen,--degraded; many of them, as races, hopelessly lost. For all experience serves to show, that when a tribe of men falls beneath a certain level, it cannot come into competition with civilized man, pressing outwards from his old centres to possess the earth, without becoming extinct before him. Sunk beneath a certain level, as in the forests of America, in Van Dieman's Land, in New South Wales, and among the Bushmen of the Cape, the experience of more than a hundred years demonstrates that its destiny is extinction,--not restoration. Individuals may be recovered by the labors of some zealous missionary; but it is the fate of the race, after a few generations, to disappear. It has fallen too hopelessly low to be restored. There remain curious traces in the New World of these perished tribes. The Bible, translated into an old Indian language, from which the devoted David Brainerd taught so successfully a nation of Red Men, still exists; but it speaks in a dead tongue, which no one can now understand; for the nation to whom he preached has become extinct. And Humboldt tells us, in referring to a perished tribe of South America, that there lived in 1806, when he visited their country, an old parrot in Maypures, which could not be understood, because, as the natives informed him, it spoke the language of the Atures. Tribes of the aborigines of Australia have wholly disappeared during the present generation; and I remember seeing it stated in a newspaper paragraph, which appeared a few years ago, that the last male survivor of the natives of Tasmania was at that time in the latter stages of consumption. But if man, in at least the more degraded varieties of the race, be so palpably _not_ what the Creator originally made him, by whom, then, was he made the poor lost creature which in these races we find him to be? He was made what he is, I reply, by man himself; and this, in many instances, by a process which we may see every day taking place among ourselves in individuals and families, though happily, not in races. Man's nature again,--to employ the condensed statement of the poet,--has been bound fast in fate, but his will has been left free. He is free either to resign himself to the indolence and self-indulgence so natural to the species; or, "spurning delights, to live laborious days;"--free either to sink into ignorant sloth, dependent uselessness, and self-induced imbecility, bodily and mental, or to assert by honest labor a noble independence,--to seek after knowledge as for hidden treasures, and, in the search, to sharpen his faculties and invigorate his mind. And while we see around us some men addressing themselves with stout, brave hearts to what Carlyle terms, with homely vigor, their "heavy job of work," and, by denying themselves many an insidious indulgence, doing it effectually and well, and rearing up well-taught families in usefulness and comfort, to be the stay of the future, we see other men yielding to the ignoble solicitations of appetite or of indolence, and becoming worse than useless themselves, and the parents of ignorant, immoral, and worse than useless families. The wandering vagrants of Great Britain at the present time have been estimated at from fifteen to twenty thousand souls; the hereditary paupers of England,--a vastly more numerous class,--have become, in a considerable degree, a sept distinct from the general community; and in all our large towns there are certain per centages of the population,--unhappily ever increasing per centages,--that, darkened in mind and embruted in sentiment, are widely recognized as emphatically the dangerous classes of the community. And let us remember that we are witnessing in these instances no new thing in the history of the species: every period since that of the vagabond Cain has had its waifs and stragglers, who fell behind in the general march. In circumstances such as obtained in the earlier ages of the human family, all the existing nomades and paupers of our country would have passed into distinct races of men. For in the course of a few generations their forms and complexions would begin to tell of the self-induced degradation that had taken place in their minds; and in a few ages more they would have become permanent varieties of the species. There are cases in which not more than from two to three centuries have been found sufficient thoroughly to alter the original physiognomy of a race. "On the plantation of Ulster in 1611, and afterwards, on the success of the British against the rebels in 1641 and 1689," says a shrewd writer of the present day, himself an Irishman, "great multitudes of the native Irish were driven from Armagh and the south of Down, into the mountainous tract extending from the Barony of Fleurs eastward to the sea; on the other side of the kingdom the same race were exposed to the worst effects of hunger and ignorance, the two great brutalizers of the human race. The descendants of these exiles are now distinguished physically by great degradation. They are remarkable for open, projecting mouths, with prominent teeth and exposed gums; and their advancing cheek bones and depressed noses bear barbarism on their very front. In Sligo and northern Mayo the consequences of the two centuries of degradation and hardship exhibit themselves in the whole physical condition of the people, affecting not only the features, but the frame. Five feet two inches on an average,--pot-bellied, bow-legged, abortively featured, their clothing a wisp of rags,--these spectres of a people that were once well-grown, able-bodied, and comely, stalk abroad into the daylight of civilization, the annual apparition of Irish ugliness and Irish want." Such is man as man himself has made him,--not man as he came from the hand of the Creator. In many instances the degradation has been voluntary; in others it has been forced upon families and races by the iron hand of oppression; in almost all,--whether self-chosen by the parents or imposed upon them,--the children and the children's children have, as a matter of inevitable necessity, been born to it. For, whatever we may think of the Scriptural doctrine on this special head, it is a fact broad and palpable in the economy of nature, that parents _do_ occupy a federal position; and that the lapsed progenitors, when cut off from civilization and all external interference of a missionary character, become the founders of a lapsed race. The iniquities of the parents are visited upon the children. And in all such instances it is _man_ left to the freedom of his own will that is the deteriorator of man. The doctrine of the Fall, in its purely theologic aspect, is a doctrine which must be apprehended by faith; but it is at least something to find that the analogies of science, instead of running counter to it, run in exactly the same line. It is one of the inevitable consequences of that nature of man which the Creator "bound fast in fate," while he left free his will, that the free will of the parent should become the destiny of the child. But the subject is one in which we can see our way as but "through a glass darkly." Nay, it is possible that the master problem which it involves no created intelligence can thoroughly unlock. It has been well said, that the "poet's heart" is informed by a "terrible sagacity;" and I am at times disposed to regard Milton's conception of the perplexity of the fallen spirits, when reasoning on "fixed fate, free will, foreknowledge absolute," and finding "no end in wandering mazes lost," much rather as a sober truth caught from the invisible world, than as merely an ingenious fancy. The late Robert Montgomery has rather unhappily chosen Satan as one of the themes of his muse; and in his long poem, designated in its second title "Intellect without God," he has set that personage a-reasoning in a style which, I fear, more completely demonstrates the absence of God than the presence of intellect. It has, however, sometimes occurred to me, that a poet of the larger calibre, who to the Divine faculty and vision added such a knowledge of geologic science as that which Virgil possessed of the Natural History of his time, or as that which Milton possessed of the general learning of _his_, might find, in a somewhat similar subject, the materials of a poem which "posterity would not willingly let die." There is one of the satirists justly severe on a class of critics "Who, drily plain, without invention's aid, Write dull receipts how poems may be made." But at some risk of rendering myself obnoxious to his censure, I shall attempt indicating at least the general scope and character of what the schoolmen might term a _possible_ poem; which, if vivified by the genius of some of the higher masters of the lyre, broad of faculty, and at once great poets and great men, might prove one precious boon more to the world, suited, conformably to the special demands of these latter times, to "assert Eternal Providence, And justify the ways of God to man." There has been war among the intelligences of God's spiritual creation. Lucifer, son of the morning, has fallen like fire from heaven; and our present earth, existing as a half-extinguished hell, has received him and his angels. Dead matter exists, and in the unembodied spirits vitality exists; but not yet in all the universe of God has the vitality been united to the matter; animal life, to even the profound apprehension of the fallen angel, is an inconceivable idea. Meanwhile, as the scarce reckoned centuries roll by, vacantly and dull, like the cheerless days and nights over the head of some unhappy captive, the miserable prisoners of our planet become aware that there is a slow change taking place in the condition of their prison-house. Where a low, dark archipelago of islands raise their flat backs over the thermal waters, the heat glows less intensely than of old; the red fire bursts forth less frequently; the dread earthquake shakes more rarely; save in a few centres of intenser action, the great deep no longer boils like a pot; and though the heavens are still shut out by a gray ceiling of thick vapor, through which sun or moon never yet appeared, a less gloomy twilight struggles at noonday through the enveloping cloud, and falls more cheerfully than heretofore upon land and sea. At length there comes a morning in which great ocean and the scattered islands declare that God the Creator had descended to visit the earth. The hitherto verdureless land bears the green flush of vegetation; and there are creeping things among the trees. Nor is the till now unexampled mystery of animal life absent from the sounds and bays. It is the highest intelligences that manifest the deepest interest in the works of the All Wise. Nor can we doubt that on that morning of creative miracle, in which matter and vitality were first united in the bonds of a strange wedlock, the comprehensive intellect of the great fallen spirit--profound and active beyond the lot of humanity--would have found ample employment in attempting to fathom the vast mystery, and in vainly asking what these strange things might mean. With how much of wonder, as scene succeeded scene, and creation followed creation,--as life sprang out of death, and death out of life,--must not that acute Intelligence have watched the course of the Divine Worker,--scornful of spirit and full of enmity, and yet aware, in the inner depths of his intellect, that what he dared insultingly to depreciate, he yet failed, in its ultimate end and purpose, adequately to comprehend! Standing in the presence of unsolved mystery, under the chill and withering shadow of that secret of the Lord which was not with him, how thoroughly must he not have seen, and with what bitter malignity felt, that the grasp of the Almighty was still upon him, and that in the ever varying problem of creation, which, with all his powers, he failed to unlock, and which, as age succeeded age, remained an unsolved problem still, the Divine Master against whom he had rebelled, but from whose presence it was in vain to flee, emphatically spake to him, as in an after age to the patriarch Job, and, with the quiet dignity of the Infinite, challenged him either to do or to know! "Shall he that coutendeth with the Almighty instruct him? He that reproveth God, let him answer. Knowest thou the ordinances of Heaven? or canst thou set the dominion thereof in the earth?" With what wild thoughts must that restless and unhappy spirit have wandered amid the tangled mazes of the old carboniferous forests! With what bitter mockeries must he have watched the fierce wars which raged in their sluggish waters, among ravenous creatures horrid with trenchant teeth, barbed sting, and sharp spine, and enveloped in glittering armor of plate and scale! And how, as generation after generation passed away, and ever and anon the ocean rolled where the land had been, or the land rose to possess the ancient seats of the ocean,--how, when looking back upon myriads of ages, and when calling up in memory what once had been, the features of earth seemed scarce more fixed to his view than the features of the sky in a day of dappled, breeze-borne clouds,--how must he have felt, as he became conscious that the earth was fast ripening, and that, as its foundations became stable on the abyss, it was made by the Creator a home of higher and yet higher forms of existence,--how must he have felt, if, like some old augur looking into the inner mysteries of animal life, with their strange prophecies, the truth had at length burst upon him, that reasoning, accountable man was fast coming to the birth,--man, the moral agent,--man, the ultimate work and end of creation,--man, a creature in whom, as in the inferior animals, vitality was to be united to matter, but in whom also, as in no inferior animal, responsibility was to be united to vitality! How must expectancy have quickened,--how must solicitude have grown,--when, after the dynasty of the fish had been succeeded by the dynasty of the reptile, and that of the reptile by the dynasty of the sagacious mammal, a time had at length arrived when the earth had become fixed and stable, and the proud waves of ocean had been stayed,--when, after species and genera in both kingdoms had been increased tenfold beyond the precedent of any former age, the Creative Hand seemed to pause in its working, and the finished creation to demand its lord! Even at this late period, how strange may not the doubts and uncertainties have been that remained to darken the mind of the lost spirit! It was according to his experience,--stretched backwards to the first beginnings of organic vitality, and coextensive, at a still earlier period, with God's spiritual universe,--that all _animals_ should die,--that all _moral agents_ should live. How, in this new creature,--this prodigy of creation, who was to unite what never before had been united,--the nature of the animals that _die_ with the standing and responsibility of the moral agents that _live_,--how, in this partaker of the double nature, was the discrepancy to be reconciled? How, in this matter, were the opposite claims of life and death to be adjusted, or the absolute _immortality_, which cannot admit of degrees, to be made to meet with and shade into the _mortality_ which, let us extend the term of previous vitality as we may, must forever involve the antagonistic idea of final annihilation and the ceasing to be? At length creation receives its deputed monarch. For, moulded by God's own finger, and in God's own likeness, man enters upon the scene, an exquisite creature, rich in native faculty, pregnant with the yet undeveloped seeds of all wisdom and knowledge, tender of heart and pure of spirit, formed to hold high communion with his Creator, and to breathe abroad his soul in sympathy over all that the Creator had made. And yet, left to the freedom of his own will, there is a weakness in the flesh that betrays his earthly lineage. It is into the dust of the ground that the living soul has been breathed. The son of the soil, who, like the inferior animals, his subjects, sleeps and wakes, and can feel thirst and hunger, and the weariness of toil, and the sweets of rest, and who come under the general law, "increase and multiply," promulgated of old to them, stands less firmly than the immaterial spirits stood of old; and yet even they rebelled against Heaven, and fell. There awakes a grim hope in the sullen lord of the first revolt. Ages beyond tale or reckoning has this temple of creation been in building. Long have its mute prophecies in fishes and in creeping things, in bird and in beast, told of coming man, its final object and end. And now there needeth but one blow, and the whole edifice is destroyed, God's purposes marred and frustrated, and this new favorite of earth dashed back to the dust out of which he was created, and brought, like the old, extinct races, under the eternal law of death. Armed with the experience in evil of unsummed ages, the Tempter plies his work: nor is it to low or ignoble appetites that he appeals. It is to the newly-formed creature's thirst for knowledge; it is to his love stronger than death. The wiles of the Old Serpent prevail; man falls prostrate before him; creation trembles; and then from amid the trees of the garden comes the voice of God. And lo! in an enigma mysterious and dark a new dispensation of prophecy begins. Victims bleed; altars smoke; the tabernacle arises amid the white tents of the desert; the temple ascends all glorious on the heights of Mount Zion; prophet after prophet declares his message. At length, in the fulness of time, the Messiah comes; and, in satisfying the law, and in fulfilling all righteousness, and in bringing life and immortality to light, abundantly shows forth that the terminal dynasty of all creation had been of old foreordained, ere the foundations of the world, to possess for its eternal lord and monarch, not primeval man, created in the image of God, but God, made manifest in the flesh, in the form of primeval man. But how breaks on the baffled Tempter the sublime revelation? Wearily did he toil,--darkly did he devise, and take, in his great misery, deep counsel against the Almighty; and yet all the while, while striving and resisting as an enemy, has he been wielded as a tool; when, glaring aloof in his proud rebellion, the grasp of the Omnipotent has been upon him, and the Eternal Purposes have encompassed him, and he has been working out, all unwittingly, the foreordained decree, "For our God maketh the wrath of the wicked to praise him, and the remainder thereof doth he restrain." But enough, for the present, of the poems that might be. Permit me, however, to add, in the words of one of the most suggestive, and certainly not least powerful, of English thinkers, that "a fall of some sort or other,--the creation, as it were, of the non-absolute,--is the fundamental postulate of the moral history of man. Without this hypothesis," he adds, "man is unintelligible,--with it every phenomenon is explicable. The mystery itself is too profound for human insight." Such, in this matter, was the ultimate judgment of a man who in youth had entertained very opposite views,--the poet Coleridge. It has been said that the inferences of the geologist militate against those of the theologian. Nay, not those of our higher geologists and higher theologians,--not what our Murchisons and Sedgwicks infer in the one field, with what our Chalmerses and Isaac Taylors infer in the other. Between the Word and the Works of God there can be no actual discrepancies; and the seeming ones are discernible only by the men who see worst. "Mote-like they flicker in unsteady eyes, And weakest his who best descries." The geologist, as certainly as the theologian, has a province exclusively his own; and were the theologian ever to remember that the Scriptures could not possibly have been given to us as revelations of scientific truth, seeing that a single scientific truth they never yet revealed, and the geologist that it must be in vain to seek in science those truths which lead to salvation, seeing that in science these truths were never yet found, there would be little danger even of difference among them, and none of collision. Nay, there is, I doubt not, a time coming in which the Butlers and Chalmerses of the future will be content to recognize the geologic field as that of their richest and most pregnant analogies. It is with the history of the pre-Adamic ages that geology sets itself to deal; and by carefully conning the ancient characters graven in the rocks, and by deciphering the strange inscriptions which they compose, it greatly extends the record of God's doings upon the earth. And what more natural to expect, or rational to hold, than that the Unchangeable One should have wrought in all time after one general type and pattern, or than that we may seek, in the hope of finding, meet correspondences and striking analogies between his revealed workings during the human period, and his previous workings of old during the geologic periods,--correspondences and analogies suited to establish the identity of the worker, and, of course, from that identity to demonstrate the authenticity of the revelation? Permit me to bring out, in conclusion, what I have often thought on this subject, but have not been able so tersely to express, in a brief quotation from one of the most instructive works of the present age, the "Method of the Divine Government," by the Rev. Dr. M'Cosh:--"Science has a foundation," says this solid thinker and accomplished writer, "and so has religion. Let them unite their foundations, and the basis will be broader, and they will be two compartments of one great fabric reared to the glory of God. Let the one be the outer and the other the inner court. In the one let all look, and admire, and adore; and in the other let those who have faith kneel, and pray, and praise. Let the one be the sanctuary where human learning may present its richest incense as an offering to God, and the other, the holiest of all, separated from it by a veil now rent in twain, and in which, on a blood-sprinkled mercy seat, we pour out the love of a reconciled heart, and hear the oracles of the living God." LECTURE SEVENTH. THE NOACHIAN DELUGE. PART I. There are events so striking in themselves or from their accompaniments, that they powerfully impress the memories of children but little removed from infancy, and are retained by them in a sort of troubled recollection ever after, however extended their term of life. Samuel Johnson was only two and a half years old when, in accordance with the belief of the time, he was touched by Queen Anne for the "Evil;" but more than seventy years after, he could call up in memory a dream-like recollection of the lady dressed in a black hood, and glittering with diamonds, into whose awful presence he had been ushered on that occasion, and who had done for the cure of his complaint all that legitimate royalty could do. And an ancient lady of the north country, who had been carried, when a child, in her nurse's arms, to witness the last witch execution that took place in Scotland, could distinctly tell, after the lapse of nearly a century, that the fire was surrounded by an awe-struck crowd, and that the smoke of the burning, when blown about her by a cross breeze, had a foul and suffocating odor. In this respect the memory of infant tribes and nations seems to resemble that of individuals. There are characters and events which impress it so strongly, that they seem never to be forgotten, but live as traditions, sometimes mayhap very vague, and much modified by the inventions of an after time, but which, in floating downwards to late ages, always bear about them a certain strong impress of their pristine reality. They are shadows that have become ill defined from the vast distance of the objects that cast them,--like the shadows of great birds flung, in a summer's day, from the blue depths of the sky to the landscape far below,--but whose very presence, however diffused they may have become, testifies to the existence of the remote realities from which they are thrown, and without which they could have had no being at all. The old mythologies are filled with shadowy traditions of this kind,--shadows of the world's "gray fathers,"--which, like those shadows seen reflected on clouds by travellers who ascend lofty mountains, are exaggerated into the most gigantic proportions, and bear radiant glories around their heads. There is, however, one special tradition which seems to be more deeply impressed and more widely spread than any of the others. The destruction of well nigh the whole human race, in an early age of the world's history, by a great deluge, appears to have so impressed the minds of the few survivors, and seems to have been handed down to their children, in consequence, with such terror-struck impressiveness, that their remote descendants of the present day have not even yet forgotten it. It appears in almost every mythology, and lives in the most distant countries, and among the most barbarous tribes. It was the laudable ambition of Humboldt,--first entertained at a very early period of life,--to penetrate into distant regions, unknown to the natives of Europe at the time, that he might acquaint himself, in fields of research altogether fresh and new, with men and with nature in their most primitive conditions. In carrying out his design, he journeyed far into the woody wilderness that surrounds the Orinoco, and found himself among tribes of wild Indians whose very names were unknown to the civilized world. And yet among even these forgotten races of the human family he found the tradition of the deluge still fresh and distinct; not confined to single tribes, but general among the scattered nations of that great region, and intertwined with curious additions, suggestive of the inventions of classic mythology in the Old World. "The belief in a great deluge," we find him saying, "is not confined to one nation singly,--the Tamanacs: it makes part of a system of historical tradition, of which we find scattered notions among the Maypures of the great cataracts; among the Indians of the Rio Erevato, which runs into the Caura; and among almost all the tribes of the Upper Orinoco. When the Tamanacs are asked how the human race survived this great deluge,--'_the age of water_' of the Mexicans,--they say, a man and woman saved themselves on a high mountain called Tamanacu, situated on the banks of the Asiveru, and, _casting behind them over their heads_ the fruits of the mauritia palm-tree, they saw the seeds contained in these fruits produce men and women, who re-peopled the earth. Thus," adds the philosophic traveller, "we find in all simplicity, among nations now in a savage state, a tradition which the Greeks embellished with all the charms of imagination." The resemblance is certainly very striking. "Quit the temple," said the Oracle to Deucalion and Pyrrha, when they had consulted it, after the great deluge, regarding the mode in which the earth was to be re-peopled,--"vail your heads, unloose your girdles, and throw behind your backs the bones of your grandmother." Rightly interpreting what seemed darkest and most obscure in the reply, they took "stones of the earth," and, casting them behind them, the stones flung by Deucalion became men, and those by Pyrrha became women, and thus the disfurnished world was peopled anew. The navigator always regards himself as sure of his position when he has _two_ landmarks to determine it by, or when in the open ocean he can ascertain, not only his latitude, but his longitude also. And this curious American tradition seems to have its two such marks,--its two bisecting lines of determination,--to identify it with the classic tradition of the Old World that refers evidently to the same great event. There are other portions of America in which the tradition of the Flood is still more distinct than among the forests of the Orinoco. It is related by Herrera, one of the Spanish historians of America, that even the most barbarous of the Brazilians had some knowledge of a general deluge; that in Peru the ancient Indians reported, that many years before there were any Incas, all the people were drowned by a great flood, save six persons, the progenitors of the existing races, who were saved on a float; that among the Mechoachans it was believed that a single family was preserved, during the outburst of the waters, in an ark, with a sufficient number of animals to replenish the new world; and, more curious still, that it used to be told by the original inhabitants of Cuba, that "an old man, knowing the deluge was to come, built a great ship, and went into it with his family and abundance of animals; and that, wearying during the continuance of the flood, he sent out a crow, which at first did not return, staying to feed on the dead bodies, but afterwards returned bearing with it a green branch." The resemblance borne by this last tradition to the Mosaic narrative is so close as to awaken a doubt whether it may not have been but a mere recollection of the teaching of some early missionary. Nor can its genuineness now be tested, seeing that the race which cherished it has been long since extinct. It may be stated, however, that a similar suspicion crossed the mind of Humboldt when he was engaged in collecting the traditions of the Indians of the Orinoco; but that on further reflection and inquiry he dismissed the doubt as groundless. He even set himself to examine whether the district was not a fossiliferous one, and whether beds of sea shells, or deposits charged with the petrified remains of corals or of fishes, might not have originated among the aborigines some mere myth of a great inundation sufficient to account for the appearances in the rocks. But he found that the region was mainly a primary one, in which he could detect only a single patch of sedimentary rock, existing as an unfossiliferous sandstone. And so, though little prejudiced in favor of the Mosaic record, he could not avoid arriving at the conclusion, simply in his character as a philosophic inquirer, who had no other object than to attain to the real and the true, that the legend of the wild Maypures and Tamanacs regarding a great destructive deluge was simply one of the many forms of that oldest of traditions which appears to be well nigh coextensive with the human family, and which, in all its varied editions, seems to point at one and the same signal event. Very varied some of these editions are. The inhabitants of Tahiti tell, for instance, that the Supreme God, a long time ago, being angry, dragged the earth through the sea, but that by a happy accident _their_ island broke off and was preserved; the Indians of Terra Firma believe, that when the great deluge took place, one man, with his wife and children, escaped in a canoe; and the Indians of the North American lakes hold, that the father of all their tribes being warned in a dream that a flood was coming, built a raft, on which he preserved his family, and pairs of all the animals, and which drifted about for many months, until at length a new earth was made for their reception by the "Mighty Man above." In that widely extended portion of the Old World over which Christianity has spread in its three great types,--Greek, Romish, and Protestant,--and in the scarce less extended portion occupied by the followers of Mohammed, the Scriptural account of the deluge, or the imperfect reflection of it borrowed by the Koran, has, of course, supplanted the old traditions. But outside these regions we find the traditions existing still. One of the sacred books of the Parsees (representatives of the ancient Persians) records, that "the world having been corrupted by Ahriman the Evil One, it was thought necessary to bring over it a universal flood of waters, that all impurity might be washed away. Accordingly the rain came down in drops as large as the head of a bull, until the earth was wholly covered with water, and all the creatures of the Evil One perished. And then the flood gradually subsided, and first the mountains, and next the plains, appeared once more." In the Scandinavian Edda, between whose wild fables and those of the sacred books of the Parsees there has been a resemblance traced by accomplished antiquaries such as Mallet, the tradition of the deluge takes a singularly monstrous form. On the death of the great giant Ymir, whose flesh and bones form the rocks and soils of the earth, and who was slain by the early gods, his blood, which now constitutes the ocean, rushed so copiously out of his wounds, that all the old race of the lesser giants, his offspring, were drowned in the flood which it occasioned, save one; and he, by escaping on board his bark with his wife, outlived the deluge. The tradition here is evidently allegorized, but it is by no means lost in the allegory. Sir William Jones, perhaps the most learned and accomplished man of his age (such at least was the estimate of Johnson), and the first who fairly opened up the great storehouse of eastern antiquities, describes the tradition of the deluge as prevalent also in the vast Chinese empire, with its three hundred millions of people. He states that it was there believed that, just ere the appearance of Fohi in the mountains, a mighty flood, which first "flowed abundantly, and then subsided, covered for a time the whole earth, and separated the higher from the lower age of mankind." The Hindu tradition, as related by Sir William, though disfigured by strange additions, is still more explicit. An evil demon having purloined the sacred books from Brahma, the whole race of men became corrupt except the seven Nishis, and in especial the holy Satyavrata, the prince of a maritime region, who, when one day bathing in a river, was visited by the god Vishnu in the shape of a fish, and thus addressed by him:--"In seven days all creatures who have offended me shall be destroyed by a deluge; but thou shalt be secured in a capacious vessel, miraculously formed. Take, therefore, all kinds of medicinal herbs, and esculent grain for food, and, together with the seven holy men, your respective wives, and pairs of all animals, enter the ark without fear: then shalt thou know God face to face, and all thy questions shall be answered." The god then disappeared; and after seven days, during which Satyavrata had conformed in all respects to the instructions given him, the ocean began to overflow the coasts, and the earth to be flooded by constant rains, when a large vessel was seen coming floating shore-wards on the rising waters; into which the Prince and the seven virtuous Nishis entered, with their wives, all laden with plants and grain, and accompanied by the animals. During the deluge Vishnu preserved the ark by again taking the form of a fish, and tying it fast to himself; and when the waters had subsided, he communicated the contents of the sacred books to the holy Satyavrata, after first slaying the demon who had stolen them. It is added, however, that the good man having, on one occasion long after, by "the act of destiny," drunk mead, he became senseless, and lay asleep naked, and that Charma, one of three sons who had been born to him, finding him in that sad state, called on his two brothers to witness the shame of their father, and said to them, What has now befallen? In what state is this our sire? But by the two brothers,--more dutiful than Charma,--he was hidden with clothes, and recalled to his senses; and, having recovered his intellect, and perfectly knowing what had passed, he cursed Charma, saying, "Thou shalt be a servant of servants." It would be difficult certainly to produce a more curious legend, or one more strikingly illustrative of the mixture of truth and fable which must ever be looked for in that tradition which some are content to accept even in religion as a trustworthy guide. In ever varying tradition, as in those difficult problems in physical science which have to be wrought out from a multitude of differing observations, it is, if I may so express myself, the mean result of the whole that must be accepted as approximately the true one. And the mean result of those dim and distorted recollections of the various tribes of men which refer to the Flood is a result which bears simply to this effect,--that in some early age of the world a great deluge took place, in which well nigh the whole human family was destroyed. The ancient traditions which have come down to us embalmed in classic literature form but a small portion of what seems once to have existed in the wide region now overspread by Christianity and Mohammedanism. A second deluge, more fatal to at least the productions of the human mind than the first had been, overspread the earth during what are known as the Middle Ages; and so signal was the wreck which it occasioned, that of seven heathen writers[24] whose testimony regarding the Flood Josephus cites as corroborative of his own, not one has descended in his writings to these later times. We learn, however, from the Jewish historian, that one of their number, Berosus, was a Chaldean; that two of the others, Hieronymus and Manetho, were Egyptians; and that a third, Nicolaus, whose history he quotes, was a citizen of Damascus. "There is," said this latter writer, in his perished history, "a great mountain in Armenia, over Minyas, called Baris, upon which it is reported that many who fled at the time of the deluge were saved; and that one who was carried in an ark came on shore on the top of it; and that the remains of the timber were a great while preserved. This might be the man," added this forgotten writer, "about whom Moses, the legislator of the Jews, wrote." The works of the Chaldean, Berosus, have long since been lost, all save a few extracts preserved by the Patristic writers. One of these, however, which embodies the Chaldean tradition of the Flood, is very remarkable. Like the Scandinavian legend, it represents the antediluvians as giants, all of whom, save one, became exceedingly impious and depraved. "But there was one among the giants," says Berosus, "that reverenced the gods, and was more wise and prudent than all the rest. His name was Noa; he dwelt in Syria, with his three sons, Sem, Japet, Chem, and their wives, the great Tidea, Pandora, Noela, and Noegla. This man, fearing the destruction which, he foresaw from the stars, would come to pass, began, in the seventy-eighth year before the inundation, to build a ship covered like an ark. Seventy-eight years from the time he began to build
