Summary

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

Summary

TWW should look at bee and comb specimens received by CD from Africa.

Summary

Thanks WED for his botanical specimens and observations.

Discusses Corydalis and the fertilisation of Fumariaceae.

Summary

CD is too ill to write.

As for natural selection, he is more faithful to PM’s "own original child" than PM is himself. To illustrate, CD relates the metaphor of an architect selecting well-shaped stones and rejecting ill-shaped ones. [See Variation 2: 431.]

Summary

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.

Summary

Receipt for cheque enclosed.

Summary

Lyell has received compliments for letting readers draw own inferences [on species question]. Now feels he earlier did Lamarck injustice. [CD’s] substitution of variety-making power for volition [as in Lamarck] in some respects only a change of names.

Thinks Huxley taking on too many responsibilities.

Summary

Suggests a new school for CD’s son [Horace].

Summary

Notes, calculations, and diagrams on phyllotaxy.

Summary

Naudin has not answered CD’s letter.

Reactions of Candolle, Naudin, Decaisne, and Gaston de Saporta to Origin.

CD’s new hothouse.

CD’s Linum paper.

JDH’s work on Welwitschia.

Summary

Flora of Cameroons shakes JDH’s faith in ability to explain past or present migrations. Sees need for a major novel explanation such as natural selection, glacial cold, or continental connections.

Lyell in a bad way about feud with Falconer.

JDH’s opinion of Wallace, Bates, J. E. Gray, Owen, Asa Gray, Lubbock, and Bentham.

Bentham’s Linnean Society address [see 4118].

Summary

Studying self-sterility, particularly in Oncidium, where abortion occurs consistently but stigma functions normally. His hybrid orchid crosses show sterility occurs capriciously. Thus it is not a "special endowment".

Disputes Asa Gray’s and Hermann Crüger’s view of rostellar germination.

Doubts absolute sterility of Catasetum.

Disappointed by results with homomorphic cowslips.

Summary

Lyell is "half-hearted but whole-headed" for CD’s theory. George Bentham wholly converted.

Bates’s book delightful but has a Darwinistic bias.

Cameroon plants.

JDH defends Bates against J. E. Gray’s slanders.

Summary

JDH working on the New Zealand flora.

Jules Planchon excited about CD’s Linum experiments.

T. F. Jamieson’s paper on glaciers gives great pleasure.

Summary

Difference in plumage of Ardeola, a species of heron, in summer and winter. [See Descent 2: 190.]

Summary

At the suggestion of J. D. Hooker CD offers his opinion on the value of a proposed collection to be made at the Galápagos. The display would not be attractive or appealing to amateurs in natural history, but the scientific value of good collections of every species would be very great if those of each island are rigorously kept separate.

Summary

CD’s respect for JS’s indomitable work and interesting experiments increases steadily.

His gratitude for the primulas and the astonishing Gongora specimen.

Asks JS’s opinion about crossing a primrose with the pollen of a wild cowslip and of a cultivated polyanthus.

Summary

Falconer going to France in defence of his views.

On scientific squabbling.

Herschel’s theory of the earth.

Bates’s book.

Summary

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.

Summary

Evidence of tropical floras continuous since Tertiary cannot fit CD’s position on intermittent cold periods.

Agrees with CD on reversion and latency.
