One of the most renowned nineteenth-century British explorers of Africa, David Livingstone (1813–73) was a medical missionary who received the Royal Geographical Society gold medal in 1855. His fame was established by his 1853–6 coast-to-coast exploration of the African interior, and by the best-selling Missionary Travels and Researches in South Africa, published upon his return to England in 1857 (also reissued in this series). Livingstone's last expedition in search of 'the true source of the Nile', undertaken in 1866, forms the core of this two-volume travel diary, published posthumously in 1874. Volume 1 describes his illness-plagued journey from Zanzibar to Ujiji, in Western Tanzania. It also records his 1871 encounter with the New York Herald correspondent and explorer Henry Morton Stanley, who had been dispatched to find him after Livingstone had been cut off from the outside world for so long that he was presumed dead.
