Account of Speke's first expedition in search of the source of the Nile, in 1856-59, undertaken with Sir Richard Burton. They started at Zanzibar and moved into East Africa, eventually discovering Lake Tanganyika. Burton was taken ill at this point and remained in camp while Speke continued on, as he did not believe that their location was in fact the source. Pushing on he became the first European to discover what he named Lake Victoria and claimed it to be the source (although he did not find an outflowing river) but Burton disputed it, leading to a long-running bitter feud between the two men (see previous 2 lots). Alexander George Findlay (1812-75), geographer and hydrographer. "He was also active in mapping the discoveries being made in Africa and the quest for the source of the Nile. He was a friend of David Livingstone and made the official maps of the routes taken by Burton and Speke in their journeys in 1858-9." ODNB
