This set provides a fascinating insight into the early study of African languages and religion. Robert Needham Cust's encyclopedic Sketch of Modern Languages of Africa divides languages into sub-groups and examines the characteristics of each language; his studies include the Bantu family, the Khoisian group and the Hottentot Bushman group. Hahn's Tsuni-Goam: the supreme being of the IKhoi-khoi written in 1880, is a valuable study of the religion and culture of the Khoi, paying particular reference to their language.
