A New Method For Discovering The Longitude Both At Sea And Land is a book written by William Whiston in 1715. The book presents a new method for determining longitude, which was a significant problem for navigators at the time. Whiston's method involves using the positions of the moon and stars to calculate longitude, rather than relying on traditional methods such as dead reckoning or the use of a chronometer. The book includes detailed instructions and tables for using this method, as well as a discussion of the history of longitude and the various methods that had been proposed up to that point. It was an important contribution to the field of navigation and helped to improve the accuracy of sea travel.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
