Encloses a sketch of the principal events in his life [for RH’s memoir on CD in Walford, ed., Portraits of men of eminence (1863–7)].

Asks for information on coloration and proportions of sexes in butterflies and moths for his work on sexual selection.
Thanks EW for information [on expression] about Australians.
Discusses factors possibly influencing the sex of caterpillars. Is gathering information on sex ratios in insects and would welcome any cases in which males seem to outnumber females.
Thanks HTS for his valuable information. Hopes to arrive at probable answer to question of proportion of males to females in the progeny of butterflies bred in domestication.
On courtship of butterflies, CD believes something more than chance is involved in determining which male is successful.
Sends elephant tooth from Africa. Suggests it may be interesting in light of his [mistaken] memory of Cuvier’s opinion about tusk brought from Peru by Humboldt.
Requests that Charles Lyell be permitted to borrow the coral reef specimens he presented to the British Museum.
Drosophyllum plants recovering [from trip]. Describes experiments on them.
Testimonial letter for GRW for position at British Museum.
Congratulates GRW on appointment to position at British Museum.
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.
Is pleased to hear that the translator for the Dutch edition [of Descent] is a person so well qualified [see 7384]. He encloses a facsimile of the title page. Reports arrangements with John Murray.
Encloses an article he wrote for the Scotsman [9 Mar 1871, p. 5].
Wishes he had time to write a critique of Descent. There is evidence of design and benevolence in nature. Beauty cannot be accounted for by natural selection.
Asks that in the event of his death, Emma should have the sketch of his species theory edited and published. Suggests possible editors, among them Lyell, Edward Forbes, and J. D. Hooker. [CD annotation on cover: "Hooker by far best man to edit my species volume Aug 1854".]
Thanks AGB for "various notes".
Would like to hear his views about the Brahmaea.
Thanks for letter [8137]. Finds observation at Stonehenge of depth of mould at different parts of slope "most valuable".
Feels that StGJM’s review of Descent [Q. Rev. 131 (1871): 47–90] greatly misrepresents CD’s opinions and conclusions. Feels their differences of opinion are so great that discussion of almost any subject would be a waste of both their time.
Asks FD questions about his sketch [missing] of ridges and furrows. [FD’s answers are interlined.]
Wishes their correspondence regarding their differences to be dropped, as CD feels that nothing he could say would have any influence on StGJM.
Discusses earthworm activity observed in old ploughed fields.
