One of the most important Burton titles, considered by many to be his best piece of writing.

Burton travelled with Speke on their second journey together in order to find the Jebel Kumri, or the 'Mountains of the Moon'. They made a brief examination of Lake Tanganyika, but with failing health they were forced to return to Kazeh to recuperate. Following this, Burton sent Speke off by himself to investigate a large lake. Speke became convinced that this was the source of the Nile; a conclusion disputed by Burton which led to their falling out and, probably, Speke's mysterious death. This work contains Burton's first attack on Speke in print.

First edition, 2 volumes, 8vo, xviii, 412; viii, 468 pp., 12 tinted woodcut plates, 22 woodcut illustrations in the text, folding tinted map, original red cloth gilt, neat repairs to spine extremities, '90' in ink to titles, a very good set.
