"Map of the World on the Mercator Projection, Exhibiting the American Continent as Its Centre", Mitchell, Samuel Augustus

This crisply engraved map with the Western Hemisphere at center features the tracks of several explorers including Cook, Gore, and Ross. In this first edition map, the continent of Antarctica is named, but only small portions of its coastline are delineated, naming Graham's Land, Palmer's Land, and showing the track of the U.S. Exploring Expedition. The Trans-Atlantic telegraph cable is shown between Newfoundland and Ireland. Alaska is shown here Russian Territory.
