Author Description

Lucas's Tables for Finding the Longitude by the Meridian Altitude, at Sea, Without the Aid of a Chronometer is a book written by William Lucas and first published in 1864. The book is a comprehensive guide for mariners and navigators who need to determine their longitude while at sea, without the use of a chronometer. The book includes detailed instructions on how to use the tables, as well as information on the theory and principles behind the calculations. The tables themselves are based on the altitude of the sun at noon, and provide a means of calculating longitude using only a sextant and a nautical almanac.Lucas's Tables were intended as a supplement to existing navigation methods, and were particularly useful for sailors who did not have access to a chronometer or other advanced navigational tools. The book was widely used by mariners in the late 19th and early 20th centuries, and helped to improve the accuracy and reliability of navigation at sea.Today, Lucas's Tables are considered a valuable historical resource for anyone interested in the history of navigation or the development of maritime technology. The book provides a fascinating glimpse into the challenges faced by sailors in the past, and the ingenuity and resourcefulness they used to overcome them.Including New And Concise Tables For Working The System, Together With A Table Showing The Daily Variation Of The Equation Of Time Under The Meridian Of Greenwich.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
