Summary

Wishes to propose John Lubbock as a member of the Entomological Society.

Asks for B. H. Hodgson’s pamphlet on sheep ["Tame sheep and goats", J. Asiat. Soc. Bengal 16 (1847): 1003–26]. Asks for odd numbers of GRW’s work [A natural history of the Mammalia (1846–8)]. Regrets that this work has stopped.

Summary

Comments on GRW’s paper [Rep. BAAS (1843): 65–7; Ann. & Mag. Nat. Hist. 12 (1843): 399–412]. CD says by "link" between any two groups he never understood a half-way link, merely one in a long series. Observes that one cannot have a simple species intermediate between two great families. Criticises GRW’s use of circles to represent groups, which leads to thinking that groups are of equal value.

Summary

Wishes to know the correct name for the British Museum’s specimen of an Abyssinian wolf described by Wilhelm Rueppell, Neue Wirbelthiere zu der Fauna von Abyssinien [1835–40] .

Summary

Congratulates GRW on appointment to position at British Museum.

Summary

Has no objection to uniting Monotremata and other marsupials but would object to doing so solely on ground that Monotremata consists of only two species. Members of a natural group need not share common character so long as they are linked with those which do. Believes that if every organism that ever lived were collected, a perfect series would be presented. What are reasons that unite Aptera and Diptera?

Summary

Thanks GRW for his sympathy on his ill health. Feels better lately.

Sends thanks to G. P. Deshayes for his advice.

Asks what "original work" GRW has begun so his name will become better known.

Summary

A page of [unspecified] text is missing from a parcel of material received from GRW.

CD "hopes and expects to live to see Carboniferous, & perhaps even Silurian, mammifers!"

Has several questions to ask whenever they meet.

Summary

Thanks GRW for collection [of insects] he has made up for CD’s nephew.

Leaves decision to GRW as to which institutions should receive CD’s Beagle insects.
