In 1872, the author of the present work at Sacramento, California, commenced an investigation with the object of illustrating by photography some phases of animal movements. In that year his experiments were made with a famous horse—Occident, owned by Senator Stanford—and photographs were made, which illustrated several phases of action while the horse was trotting at full speed, laterally, in front of the camera.
The experiments were desultorily continued; but it was not until 1877 that the results of any of them were published.
In the meanwhile he devised an automatic electro-photographic apparatus, for the purpose of making consecutive photographic exposures at regulated intervals of time or of distance. Some of the results of his experiments with this apparatus, which illustrated successive phases of the action of horses while walking, trotting, galloping, &c., were published in 1878, with the title of "The Horse in Motion." Copies of these photographs were deposited the same year in the Library of Congress at Washington, and some of them found their way to Berlin, London, Paris, Vienna, &c., where they were commented upon by the journals of the day.
In 1882, during a lecture on "The Science of Animal Locomotion in its relation to Design in Art," given at the Royal Institution (see Proceedings of the Royal Institution of Great Britain, March 13, 1882), he exhibited the results of some of his experiments made during a few antecedent years at Palo Alto, California; when he, with the zoopraxiscope and an oxy-hydrogen lantern, projected on the wall a synthesis of many of the actions he had analysed.
It may not be considered irrelevant if he repeats what he on that occasion said in his analysis of the quadrupedal walk:—
"So far as the camera has revealed, these successive foot fallings are invariable, and are probably common to all quadrupeds....
"It is also highly probable that these photographic investigations—which were executed with wet collodion plates, with exposures not exceeding in some instances the one five-thousandth part of a second—will dispel many popular illusions as to the gait of a horse, and that future and more exhaustive experiments, with the advantages of recent chemical discoveries, will completely unveil to the artist all the visible muscular action of men and animals during their most rapid movements....
"The employment of automatic apparatus for the purpose of obtaining a regulated succession of photographic exposures is too recent for its value to be properly understood, or to be generally used for scientific experiment. At some future time the explorer for hidden truths will find it indispensable for his investigations."
In 1883, the University of Pennsylvania, with an enlightened exercise of its functions as a contributor to human knowledge, instructed the author to make, under its auspices, a comprehensive investigation of "Animal Locomotion" in the broadest significance of the words.
and the arrangement of the apparatus used for this purpose is here given.
TT represents the track along which the model M was caused to move. B is the background, divided into spaces of 5 centimetres square for the purpose of measurement.
L, a horizontal battery of electro-photographic cameras, parallel to the line of motion (at a distance of 15 metres or about 48 feet therefrom), for a series of 12 lateral exposures.
R, a vertical battery of electro-photographic cameras, at right angles to the lateral battery, for a series of 12 rear foreshortenings.
F, a horizontal battery of electro-photographic cameras, at any suitable angle to the lateral battery for a series of front foreshortenings.
O, the position of the electric batteries, a chronograph for recording the time intervals of exposures, and other apparatus used in the investigation.
A clock-work apparatus, set in motion at the will of the operator, distributed a series of electric currents, and synchronously effected consecutive exposures in each of the three batteries of cameras.
The intervals of exposures were recorded by the chronograph, and divided into thousandths of a second. These intervals could be varied at will from seventeen one-thousandth parts of a second to several seconds.
The task of making the original negatives was completed in 1885; the remaining years have been devoted to the preparation of the work for publication.
Lateral elevation of some consecutive phases of action by representative horses.
Each line illustrates the successive fallings of the feet during a single stride.
After the last phase illustrated, the feet, during continuous motion, will revert practically to their position in the first phase.
The comparative distances of the feet from each other or from the ground are not drawn to scale; and, in any event, would be merely approximate for the succeeding stride.
In the conjectural stride No. 10, phase 3 is very doubtful, phases 5 and 7 seem probable in a very long stride.
The results of this investigation are
Seven Hundred and Eighty-one Sheets of Illustrations, containing more than 20,000 figures of men, women, and children, animals and birds, actively engaged in walking, galloping, flying, working, jumping, fighting, dancing, playing at base-ball, cricket, and other athletic games, or other actions incidental to every-day life, which illustrate motion or the play of muscles.
These sheets of illustrations are conventionally called "plates."
Each plate illustrates the successive phases of a single action, photographed with automatic electro-photographic apparatus at regulated and accurately recorded intervals of time, consecutively from one point of view; or, consecutively AND synchronously from two, or from three points of view.
Each Plate is complete in itself without reference to any other Plate.
When the complete series of twelve consecutive exposures, from each of the three points of view, are included in One Plate, the arrangement is usually thus:—
| 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 |
Laterals. |
|
| 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 |
Rear Foreshortenings from points of view on the same vertical line, at an angle of 90° from the Laterals. |
|
| 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 |
Front Foreshortenings from points of view on the same horizontal plane, at suitable angles from the Laterals. |
The plates are not photographs in the common acceptation of the word, but are printed in Permanent Ink, from gelatinised copper-plates, by the New York Photo-Gravure Company, on thick linen plate-paper.
The size of the paper is 45 × 60 centimetres—19 × 24 inches, and the printed surface varies from 15 × 45 to 20 × 30 centimetres—6 × 18 to 9 × 12 inches.
The number of figures on each plate varies from 12 to 36.
To publish so great a number of plates as one undivided work was considered unnecessary, for each subject tells its own story; and inexpedient, for it would defeat the object which the University had in view, and limit its acquisition to large Libraries, wealthy individuals, or Institutions where it would be beyond the reach of many who might desire to study it.
It has, therefore, been decided to issue a series of One Hundred Plates, which number, for the purposes of publication, will be considered as a "COPY" of the work. These one hundred plates will probably meet the requirements of the greater number of the subscribers.
In accordance with this view is issued the following
ANIMAL LOCOMOTION,
AN ELECTRO-PHOTOGRAPHIC INVESTIGATION OF CONSECUTIVE PHASES
OF ANIMAL MOVEMENTS,
BY
EADWEARD MUYBRIDGE.
1872-1885.
PUBLISHED UNDER THE AUSPICES OF THE
UNIVERSITY OF PENNSYLVANIA.
Exclusively by Subscription.
CONSISTING OF A SERIES OF
ONE HUNDRED PLATES,
AT A SUBSCRIPTION PRICE OF
One Hundred Dollars
For the United States, or
Twenty Guineas
For Great Britain;
Or the equivalent of Twenty Guineas in the gold currency
of other countries in Europe.
This will be for
Austria,
Two Hundred and Ten Florins;
Belgium, France, Italy, and Switzerland,
Five Hundred and Twenty-five Francs;
Germany,
Four Hundred and Twenty Marks;
Holland,
Two Hundred and Fifty Guilders.
The Plates are enclosed in a strong, canvas-lined, full American-Russia Leather Portfolio.
For the purpose of placing all of the subscribers upon an equal footing in regard to cost, a copy of the work will be sent in the portfolio, and packed between boards, to any well-established Institution, or to any subscriber, properly endorsed, to any city in Central or Western Europe, or in the United States.
Freight Charges Paid,
if so requested, to the railway station, with the understanding that the subscription price is remitted within one week of the day of the arrival of the work at the station.
Custom duties, or any other expenses, if any, at the cost of the subscriber.
Additional Plates in any required number will be supplied to the subscriber at the same proportionate rate; these, however, must be ordered at the same time as the subscription Plates.
The Plates will be supplied
Exclusively To Subscribers.
It was considered inadvisable to make an arbitrary selection of the one hundred Plates offered to subscribers, and with the object of meeting, as far as possible, their diverse requirements, they are invited to make their own selection, either from the subjoined list of subjects, or from a detailed catalogue, which will be forwarded free of expense to every subscriber.
The following are the numbers of Plates published of each class of subjects, from which the subscriber's selection can be made:—
| Plates Published. | ||
| Men, | draped | 6 |
| " | pelvis cloth | 72 |
| " | nude | 133 |
| Women, | draped | 60 |
| " | transparent drapery and semi-nude | 63 |
| " | nude | 180 |
| Children, | draped | 1 |
| " | nude | 15 |
| Movements of a man's hand | 5 | |
| Abnormal movements, men and women, nude and semi-nude | 27 | |
| Horses walking, trotting, galloping, jumping, &c. | 95 | |
| Mules, oxen, dogs, cats, goats, and other domestic animals | 40 | |
| Lions, elephants, buffaloes, camels, deer, and other wild animals | 57 | |
| Pigeons, vultures, ostriches, eagles, cranes, and other birds | 27 | |
| Total number of Plates | 781 | |
| Containing more than 20,000 Figures. | ||
Should the selection be made from the Catalogue, it will be advisable to give the Author permission to change any one of the selected Plates for any other illustrating the same action, if, in his judgment, the substituted Plate illustrates that action with a better model, or in a more perfect manner than the one selected.
With regard to the selection of Plates, however, it has been found by experience that unless any special subject or plate is required it will be more satisfactory to the subscriber if he gives the Author GENERAL INSTRUCTIONS as to the CLASS of subjects desired and to leave the SPECIFIC selection to him.
Many of the large Libraries and Art or Science Institutions in America and in Europe have subscribed for, and[Pg 13] have now in their possession, a complete series of the seven hundred and eighty-one Plates, the subscription price for which is
Five Hundred Dollars
in the United States,
One Hundred Guineas
in Great Britain for the complete series, in eight full American-Russia leather portfolios, or if bound in eleven volumes, each plate hinged, full American-Russia leather,
Five Hundred and Fifty Dollars
in the United States,
One Hundred and Ten Guineas
in Great Britain; or its equivalent for any city in Central or Western Europe.
Subscribers who wish to make use of these Plates for the promotion or diffusion of knowledge, or for artistic or scientific purposes, will be afforded facilities for acquiring working copies by special arrangement with the Author.
This is not exactly the place nor the time for the Author to express his obligations and thanks to those gentlemen who have assisted him in his labours, but it affords a perhaps not inappropriate opportunity for him to pay a tribute of gratitude to his recently deceased friend M. Meissonier, without whose enthusiastic encouragement it is probable the present work would never have been undertaken.
In 1882 he invited his friends to attend an illustrated Lecture given in his studio by the Author, and then referring to a full knowledge of a subject being necessary for it to be truthfully or satisfactorily translated by the artist, declared how much his own impression of a horse's[Pg 14] motion had been changed after having carefully studied its consecutive phases. Attention need not be directed to the modifications in the expression of animal movements now progressing in the works of the Painter and the Sculptor.
The investigations of the Author are so well known, and so generally recognised as affording the only basis of truthful interpretation or accurate criticism of Animal Movement, that it is unnecessary to quote from the many elaborate reviews of "Animal Locomotion," which have been published in the American, English, French, and German Scientific, Artistic, and other Journals.
For the value of the present work to the general student of Nature and the lover of Art, no less than to the Artist and the Archæologist, the Physiologist and the Anatomist, it is with much pride and gratitude that he refers to the annexed list of some of his European subscribers.
E. M.

Section 2. Information about the Mission of Project Gutenberg-tm
Project Gutenberg-tm is synonymous with the free distribution of
electronic works in formats readable by the widest variety of computers
including obsolete, old, middle-aged and new computers. It exists
because of the efforts of hundreds of volunteers and donations from
people in all walks of life.
Volunteers and financial support to provide volunteers with the
assistance they need, are critical to reaching Project Gutenberg-tm's
goals and ensuring that the Project Gutenberg-tm collection will
remain freely available for generations to come. In 2001, the Project
Gutenberg Literary Archive Foundation was created to provide a secure
and permanent future for Project Gutenberg-tm and future generations.

Section 4. Information about Donations to the Project Gutenberg
Literary Archive Foundation
Project Gutenberg-tm depends upon and cannot survive without wide
spread public support and donations to carry out its mission of
increasing the number of public domain and licensed works that can be
freely distributed in machine readable form accessible by the widest
array of equipment including outdated equipment. Many small donations
($1 to $5,000) are particularly important to maintaining tax exempt
status with the IRS.
The Foundation is committed to complying with the laws regulating
charities and charitable donations in all 50 states of the United
States. Compliance requirements are not uniform and it takes a
considerable effort, much paperwork and many fees to meet and keep up
with these requirements. We do not solicit donations in locations
where we have not received written confirmation of compliance. To
SEND DONATIONS or determine the status of compliance for any
particular state visit http://pglaf.org
While we cannot and do not solicit contributions from states where we
have not met the solicitation requirements, we know of no prohibition
against accepting unsolicited donations from donors in such states who
approach us with offers to donate.
International donations are gratefully accepted, but we cannot make
any statements concerning tax treatment of donations received from
outside the United States. U.S. laws alone swamp our small staff.
Please check the Project Gutenberg Web pages for current donation
methods and addresses. Donations are accepted in a number of other
ways including checks, online payments and credit card donations.

Section 5. General Information About Project Gutenberg-tm electronic
works.
Professor Michael S. Hart is the originator of the Project Gutenberg-tm
concept of a library of electronic works that could be freely shared
with anyone. For thirty years, he produced and distributed Project
Gutenberg-tm eBooks with only a loose network of volunteer support.
Project Gutenberg-tm eBooks are often created from several printed
editions, all of which are confirmed as Public Domain in the U.S.
unless a copyright notice is included. Thus, we do not necessarily
keep eBooks in compliance with any particular paper edition.
Most people start at our Web site which has the main PG search facility:
http://www.gutenberg.org
This Web site includes information about Project Gutenberg-tm,
including how to make donations to the Project Gutenberg Literary
Archive Foundation, how to help produce our new eBooks, and how to
subscribe to our email newsletter to hear about new eBooks.
