What Led to the Discovery of the Source of the Nile.

First edition of Speke's account of his momentous discovery of Lakes Victoria and Tanganyika, undoubtedly less common that his Journal of the Discovery of the Source of the Nile, especially so in collector's condition. Although it was published the year after the Journal, this work documents the first expedition arranged by the Royal Geographical Society, during which his corrosive rift with Burton first developed over Speke's disputed sighting of Victoria. Speke 'had the choice in What Led … of escalating the quarrel or letting things stand as they were. In the event, he did not dramatically change the status quo, but neither did he let slip some chances to challenge Burton further, especially in his account of how he happened to go alone to the Victoria Nyanza' (Carnochan, The Sad Story of Burton, Speke, and the Nile, p. 62).
