"A New Discovery for Finding the Longitude" by William Hobbs is a scientific publication written in the early 18th century. The book details innovative methods for accurately determining longitude at sea, a pressing issue for navigation during that period. Hobbs introduces a spring movement mechanism as part of his proposed solution, which claims to achieve precise timekeeping essential for calculating longitudinal differences. In the content of the book, Hobbs outlines the principles
for utilizing his timekeeping device to establish one's geographical position longitudinally. He explains the process for setting the device in motion, recording its indexes, and making necessary calculations based on celestial observations, particularly the sun's position. Hobbs emphasizes that this method can yield accurate results regardless of environmental influences, provided that specific conditions are met. The text includes detailed instructions for the operation of the device and offers examples to illustrate the methodology, ensuring that navigators can apply it effectively in various maritime conditions.
