His zoological Botanical and ethnographic collections are mostly in Paris (Muséum national d"histoire naturelle and Musée du quai Branly) as was his agreement with the French Government but a small collection of insects from Equatorial Africa is in the Oxford University Museum of Natural History and some expedition papers and early stereo photographs are in the Pitt Rivers Museum.
