Material relating to the 1841 and 1857 Niger expeditions. Only a few printed papers for the 1841 expedition but for the 1857 expedition there are journals, notes, financial and general papers, albeit mainly from a Wesleyan Methodist missionary persepective.
General papers include information on the WMMS Foulah mission and in particular a volume entitled 'West African Translations', relating to the work of Rev Robert MacBrair, as well as a few printed papers of the Society for the Extinction of the Slave Trade and for the Civilization of Africa.
