This is a corrected edition of Edmund Halley's landmark 1701 chart with the same title. Peter Barbour hailed that chart as the "most significant cartographic achievement of Williamite England" (The Age of William III & Mary II, plate 106.) It was one of the earliest thematic maps, and the first to show lines of equal magnetic variation which was an important advance for navigation. A version of Halley's chart was added to the Fourth Book in 1721, but was discontinued in favor of this revised version in 1749.
