This is a beautiful example of A. J. Johnson and Ross C. Browning's 1860 first edition map of the world on a hemispherical projection. Offering a fascinating snapshot of the world during a period of rapid globalization and discovery, the map depicts the world divided into the Western and Eastern Hemispheres. Africa is largely 'unexplored' though Lake Uniamesi, something that may be taken for an embryonic form of Lake Victoria, Lake Tanganyika or both, does appear. This curious lake, supposedly identified by Speak, was frequently written of in mid-century missionary reports as the source of several important African river systems, including the Congo. The Antarctic continent is shown only sketchily, representing the relatively primitive state of Antarctic exploration in 1861.
The whole is surrounded by the strapwork border used for Johnson's atlas maps from 1860 to 1863. Published by A. J. Johnson and Ross C. Browning as plate nos. 4 and 5 in the 1860 first edition edition of Johnson's New Illustrated Family Atlas.
