Requests testimonial from CD for position of Assistant Keeper, Zoological Dept, British Museum.

Are tropical fruit on the whole more or less coloured than those in the temperate zone - is proportion of red, yellow, black & white fruit, & those which are green or brown greater in the tropical or the temperate flora? [is thinking of wild fruit only here] - has anyone written on the subject? - would be important one way or the other to the question of the colour sense in animals and sexual selection as discussed in Grant Allen's clever book on the Colour Sense which ARW is writing a review of. Has heard nothing about "Epping Forest" - Sir Arthur Hobhouse - article by ARW on Epping Forest - "Epping Forest, and how best to deal with it", Fortnightly Review 24, 628-45 (1 Nov 1878)].
