Travels of Richard and John Lander into the interior of Africa, for the discovery of the course and termination of the Niger / From unpublished documents in the possession of the late Capt. John William Barber Fullerton ... with a prefatory analysis of the previous travels of Park, Denham, Clapperton, Adams, Lyon, Ritchie, &c. into the hitherto unexplored countries of Africa

Two brothers undertake a riverine expedition that traces the Niger from its upper reaches to the sea, narrating their navigation, hardships, encounters, and ultimate discovery of the river's termination. A prefatory analysis synthesizes earlier journeys by Park, Denham, Clapperton, Adams, Lyon, and others, assessing competing theories and previous failures. The volume compiles unpublished documents and detailed chapters on routes, desert crossings, major towns such as Timbuctoo and Mourzouk, local customs, commerce, religion, and the slave trade, and records illness, deaths, and diplomatic encounters. Natural history, geography, and ethnographic observations are interwoven with travel narrative to present a comprehensive account of West African exploration.
