| Description | A new and correct chart shewing the variations of the compass in the Western & Southern Oceans as observed in ye year 1700 by his Majesties command by Edm. Halley. - Sir Edmond Halley, best known for his computation of the orbit of what would come to be known as Halley's Comet, pioneered understanding of trade winds, tides, cartography, naval navigation, mortality tables, and stellar proper motions. In 1699 he explored the Atlantic Ocean and recorded its magnetic declination (isogones) or compass variations. Halley's map was the first printed map to show isogones. | ||||
