FIRST LONDON EDITION, dated April 28th 1814, and printed to accompany the first English edition of Lewis & Clark's History of the Expedition Under the Command of Captains Lewis and Clark, to the Sources of the Missouri and included in subsequent London editions. The London edition of the official map is slightly larger than the Philadelphia edition, and omits the demarcations of Indian settlements in the West.  According to Rumsey, "The map faithfully copies Samuel Lewis's map, except in the area of the "Southern Pass" where the pass itself is not named and the "Liah tan Bands" of Indians are not named."
