Copy letter from Robert William Frederick Harrison, to Professor William Gowland Harrison shares a suggestion of the Soirée Committee that Gowland may be able to suggest an exhibitor for the Royal Society's forthcoming Soirée on 9 May. He enquires whether Gowland believes a lantern demonstration of slides showing the customs and arts of natives of Lake Tanganyika, given to the Anthropological Society by Mr Cunning, would be suitable and 'novel enough'. As a previous exhibitor himself, Gowland knows the types of exhibits they like. 10 April 1906
