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.

Summary

Has been looking at separation of sexes in poplars.

Interested in reversion.

Does not understand all CD said on inheritance.

JDH now remembers that Origin was "published" some time before it was "distributed" and therefore appeared prior to his own essay [see also 2478].

Impossible to say whether some Dipterocarpaceae survived a cold period or have developed since.

Summary

Ill health.

At work on Variation.

Reading JDH on Welwitschia.

Letter from Lyell defends his position on species.

Anger at Owen.

John Lubbock’s lectures.

Summary

Sends Haast’s report; JDH may use any and all of the details in the letter.

Asks identity of a reviewer of Lyell’s Antiquity of man [Edinburgh Rev. 118 (1863): 254–302].

Summary

Asks whether he ought to write to CD while he is ill.

Wonders if he might use Haast’s notes on introduced animals for a notice he is preparing ["Note on the replacement of species in the colonies and elsewhere", Nat. Hist. Rev. n.s. 4 (1864): 123–7].

Summary

Suggests CD consult George Busk about his stomach.

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

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

Agrees with CD on reversion and latency.

Summary

Pleased with JDH’s account of his French tour.

Doctor Brinton, recommended by Busk, does not believe CD’s brain or heart affected. Feels he is going steadily downhill. If so, hopes his life will be short.

Sends Haast’s letter.

Summary

Likes JDH’s review of Alphonse de Candolle [Mémoires et souvenirs de A. P. de Candolle (1862)].

Falconer’s article on Lyell ["Primitive man. What led to the question?", Athenæum 4 Apr 1863, pp. 459–60] too severe.

CD has written a letter to the Athenæum "to say, under the cloak of attacking Heterogeny, a word in my own defence" [Collected papers 2: 78–80].

Bates’s Travels [Naturalist on the river Amazons (1863)] are excellent.
