Summary

JDH battling with Lyell over treatment of species question in Antiquity of man. Distressed by Lyell’s raising false priority issue between JDH and CD. Falconer involved in a priority squabble.

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

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

JDH lays hard treatment of John Scott to J. H. Balfour’s anti-Darwinism.

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

Observation on morphology of Primula ovarium sent for DO’s use.

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

Admits, at last, that New Zealand must have been connected to some continent, but not Australia.

Climbing plants: asks for more plants.

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

Suggests CD consult George Busk about his stomach.

Summary

British attitude towards America: not hate as Asa Gray thinks, but contempt.

Summary

Asa Gray writes as if Civil War were a holy war.

J. E. Renan on Jesus [Vie de Jésus (1863)].

Literature on tendrils of Cucurbita is contradictory.

Summary

Encourages CD to continue observations on tendrils.

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

CD’s encouragement of John Scott, who has found a case of self-incompatibility in orchids, like William Herbert’s in Crinum.

Nägeli on phyllotaxy.

CD’s observations on broom fertilisation.

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

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.

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

Lists the six honest believers in his species theory in England.

Asa Gray complains that Lyell acts like a judge on species, whereas CD complains of Lyell’s indecision.

CD working on divergence of leaves.

Distribution of Cameroon plants and the glacial theory.

Survival of island relics.

Summary

Differences between tendrils derived from leaves and those derived from branches.

CD on Asa Gray’s attitude on the Civil War.
