It covers the entire world with continents named while countries are unmarked. The Arctic regions include the voyages and discoveries of several explorers including Hudson in 1607, Phipps in 1773, Tschitsagoff in 1760, Buchan \u0026amp; Franklin in 1819 and Parry in 1827. The coast of Antarctica is drawn in sketchily, based upon early expeditions. Notes Canada's Boothia Feliin x (at the time believed to be the northern magnetic pole). The map is color coded with isothermal lines featured in green, yellow, red and blue. Various important cities, islands, oceans and other topographical details are marked. This map was engraved by George Aikman as plate no.
