Catalogue Note

AN IMPORTANT NAVIGATIONAL MANUAL. "A clear explanation of plane and spherical trigonometry is followed by a systematic demonstration of how to solve the standard navigational problems for the plain and Mercator's charts respectively, using the example of the voyage from the Lizard to the Summers Islands (Bermuda). For great circle sailing, given the latitude and longitude of the places of departure and arrival, the points where the great circle crosses a succession of meridians at a selected small interval, and the angles at which it crosses them, can be work out trigonometrically, and plotted on Mercator's chart. The course can be chosen to follow the circle as nearly as is convenient along a succession of rhumbs" (Taylor).
