Description

Second edition, 8vo (183 x 118 mm), [4], 5-104pp., two small worm pinholes to lower margin (occasionally affecting a single letter), endpapers renewed, neatly rebound in half calf, marbled boards, morocco spine label. On May 25 1714 the House of Commons had received a petition from the Royal Navy and the Merchant Marine about the necessity of discovering the longitude for safety and commerce. A committee, which included Newton and Halley, was set up and expert witnesses called. This is end second and much improved edition in which Whiston and Ditton hoped to win the Longitude prize with their suggestion that a fleet of ships be moored in the ocean 600 miles apart and fire a shell into the sky at local midnight, the time interval between seeing the flash and hearing the bang enabling a ships longitude to be calculated. The number of ships required and their cost, the problems of mooring ships in deep water and holding station, and the problems of piracy were not addressed.
