An Account Of An Attempt To Ascertain The Longitude At Sea

Zachariah Williams' account of his attempt to determine the longitude at sea using lunar observations is a fascinating insight into the early days of navigation by the stars. Williams was one of the first people to attempt this feat after the Longitude Act of 1714 offered a significant reward for anyone who could establish a reliable way to determine longitude at sea. For anyone interested in the history of science or navigation, Williams' account is a must-read.
