A lake in East Central Africa, on the Equator, is about the size of Ireland, 300 m. long and 20 m. broad, at an elevation of 3500 ft. above the sea-level; discovered by Captain Speke in 1858, and circumnavigated by Stanley in 1875; is regarded as the head-source of the Nile, the waters of it flowing through Albert Nyanza 80 m. to the N., between which two lakes lies the territory of Uganda.
