Publisher's Synopsis
""A New And Accurate Method Of Finding A Ship�������s Position At Sea, By Projection On Mercator�������s Chart"" is a book written by Thomas H. Sumner and first published in 1851. The book provides a detailed explanation of Sumner's method for determining a ship's position at sea using a Mercator's chart. The method involves measuring the altitude of a celestial body, such as the sun or a star, and using this measurement to calculate the ship's latitude and longitude. Sumner's method was a significant improvement over previous methods, which were often inaccurate and unreliable. The book includes detailed instructions and examples to help sailors and navigators use the method effectively. This book is a valuable resource for anyone interested in the history of navigation or the development of modern navigation techniques.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
