CD sends thanks for information; will write about the fins.

His health is weak and he is "almost smothered" with facts and inquiries, so is trying to restrict the scope of his present work, on variation under domestication.

Asks JJB for date of his article in the Field dealing with the regeneration of fishes’ fins; additional questions about the fish.

Thanks CL for "the great book" [Antiquity of man (1863)].

Richard Owen "ought to be ostracised by every Naturalist in England".

CL’s book will "give the whole subject of change of species an enormous advance".

Criticises Dana’s classification of man and his use of fore-limbs as a basis for systematic classification.

Asks her to translate passage of letter about treatment.

Comments at length on CL’s book [Antiquity of man (1863)]. CD is "greatly disappointed that you have not given judgment and spoken fairly out what you think about the derivation of species".

Lists large number of queries concerning minor points.

Praises especially the chapters on language and glaciers.

Comments on the temperature of Africa during the glacial period, especially with regard to the views of Hooker.

Mentions Owen’s paper on the aye-aye [Rep. BAAS 32 (1862) pt 2: 114–16].

Will send portion of copied manuscript [of Variation 2: 8–10] for WB to examine. Asks about inherited abnormalities of the eye.

[On Antiquity of man] CD is "convinced that at times … you have … given up immutability". "A clear expression from you, if you could have given it, would have been potent with the public."

Objects to CL’s description of CD’s view "as a modification of Lamarck’s doctrine". Quotes Henrietta [Darwin]’s observations on this description.

Comments on CL’s controversy with Owen concerning the human brain.

The controversy between Falconer and CL.

The "wretched" review of CL [Antiquity of man, Athenæum 14 Feb 1863, pp. 219–21] and Huxley [Man’s place in nature].

Reports the observations of Hermann Crüger and John Scott that fruit is set by orchids whose flowers never open and that pollen-tubes are emitted from pollen-masses still in their proper position. These cases convince CD that in Orchids he underestimated the power of tropical orchids to produce seed without insect aid but he is not shaken in his belief that the structure of the flowers is mainly related to insect agency.

His better opinion [of work of Boucher de Perthes].

Explains his position on CL’s treatment of species.

Mentions positive response to his ideas on the part of a German professor [Ernst Haeckel], Alphonse de Candolle, and a botanical palaeontologist [Gaston de Saporta].

Notes negative reaction of entomologists.

Mentions Falconer’s objections [to Antiquity].

Mentions work of Hooker.

Comments on paper by Owen ["On the aye-aye", Rep. BAAS 32 (1862) pt 2: 114–16]

and CD’s review of Bates’s paper [Collected papers 2: 87–92].

Thinks Natural History Review is excellent.

Thanks WDF for authentic details of number and colour of lambs [Variation 2: 30].

Complains of his eczema.

Thanks GHKT for specimens of Sethia. Discusses functions of their dimorphism for insect fertilisation.

Discusses polymorphism and fertilisation in Lythraceae.

Asks for seed of Limnanthemum.

Describes his interest in galls.

Discusses curious specimens of Gomphia and Lesemia.

Describes a letter he has written to the Athenæum in which he mentions CL’s views on species modification ["Doctrine of heterogeny", Collected papers 2: 78–80].

Comments on criticism of Lyell’s book [Antiquity] by Falconer and others.

Mentions his eczema.

Invites the Lyells to visit.

CD thanks the sender of a Cypripedium. He finds its pollination contrivances interesting.

Discussion of, and thanks for, CLB’s new work, Races of the Old World [1863]. Special interest in p. 388 on colour and constitution; CD mentions questions sent previous year to surgeons serving in tropical countries regarding diseases and colour of hair and skin.

CD is particularly struck by WFK’s observations on Corsican and N. American subspecies in his paper ["On the geographical distribution of European Rhopalocera", Trans. R. Entomol. Soc. Lond. 3d ser. 1 (1862–3): [!?bib has 1862–4] 481–92]. Thinks it would be interesting for WFK to examine specimens from the Shetland Islands, for even faint trace of differentiation.

Thanks GHKT for Limnanthemum seed.

Comments on his view of algal reproduction.

Discusses flower of Cassia.

Sends photograph of himself.

Congratulates CL on finding Arctic shells.

Comments on paper by E. B. Hunt ["On the origin, growth, substructure and chronology of the Florida reef", Am. J. Sci. 2d ser. 35 (1863): 197–210].

Mentions J. D. Dana’s health.

George Bentham’s statement on species [Proc. Linn. Soc. Lond. (1863): xi–xxix].

Family and local news, and memories of old times.

Preparation for his address with particular concern that JP approve the part relating to [Adam] Sedgwick. Urges JP to sit at dinner with him as a sign of approval of the award [of the Copley Medal].

Admits his own dismay regarding the efforts of the younger geologists and zoologists to obtain the Copley Medal for CD on the grounds of the Origin and his anxiety about the next year’s award.
