An attractive, double-hemispheric map of the world. It depicts Virginia, North Carolina, South Carolina and Georgia extending to the Mississippi River, and Florida is divided into East and West. Alaska has an indistinct coastline that extends nearly to Kamchatka with Mt. St. John near the end. A series of rivers and lakes, including a River of the West, are nearly connected from Hudson Bay to the Pacific Ocean, eluding to a possible Northwest Passage. Tasmania is still shown connected to mainland Australia, and the tracks of Cook's first voyage and Anson's voyage around the world are shown throughout the oceans. In the cusp above the map is a smaller hemispheric map featuring the North Polar regions above 50 degrees. Decorated by a rococo-style title cartouche. The map was published in both William Russell's The History of America... in 1778 and John Carver's The New Universal Traveller in 1779.
