Summary

On Asa Gray’s letter; has written why he avoids alluding to the war.

Has read Max Müller [see 3752] – last part unphilosophical.

On CD’s pigeon example, long-beaked and short-beaked pigeons must be either sterile or not inter se. There is "no such thing as Equality – hence no such thing as chance and Nat. Sel. is the sword of Damocles hanging over your head if you make a slip in your premisses."

Has read note on Lythrum sent several weeks ago. Its consequences are of most prolific order to CD’s doctrine.

Kew has no wild gooseberries.

JDH praises the Saturday Review reply [14 (1862): 589] to the Duke of Argyll’s bitter review of Orchids ["The supernatural", Edinburgh Rev. 116 (1862): 378–97].

Summary

Thanks for Aldrovanda reference and Cassia.

Has wasted labour on Melastomataceae without getting a glimpse of the meaning of the parts.

Wants seeds, from their native land, of Heterocentron or Monochaetum.

Is beginning to change his view about rarity of natural hybrids.

Summary

Had thrown Geographical Society’s Proceedings in waste-basket, but as Strachey shows such admirable powers of discrimination he will fish it out and read the whole article.

Comments on 3d ed. of Sachs’s work [Lehrbuch der Botanik (1873)]. Wishes he were more controversial.

Has become wonderfully interested in Drosera and Dionaea.

9000 copies of Expression have been printed and most are sold.

Hopes his own judgment about Origin is as good as Hooker’s about his own papers.

Strelitzia’s neat mechanism for exposing pollen.

Summary

Request for plant.

Receipt of Oliver’s letter.

Summary

A German scholar says JDH first applied natural selection to replacement of races of men, the ruder races of Polynesians yielding to civilised Europeans. CD cannot remember reading this.

Warns JDH to take care Welwitschia does not turn into a case of barnacles and consume years instead of months.

In what months do flowers appear in Acropera loddigesia and A. luteola? CD is alarmed by John Scott’s observations on them, which differ from his own. "I am very uneasy."

Summary

Comments on his Primula paper [see 4213].

Describes his situation in Calcutta.

Summary

At work on the introductory essay to Flora Tasmaniae.

Discusses the effects of climate and geography on "vegetable strife".

Summary

The Drosophyllum goes to Orpington by train this evening.

Summary

Returns Asa Gray letter. Gray has made a great blunder in his criticism of Oliver: he mistakes perpetuation of a variety for "propagation of variation". Confusion between "action of physical causes" and "effects of physical causes". Neither crossing nor natural selection has made so many divergent individuals, but simply variation. "If once you hold that natural selection can create a character your whole doctrine tumbles to the ground." CD’s failure to convey this, and the false doctrine that "like produces like" is at bottom of half the scientific infidelity to CD’s doctrine. There is something to the objection that CD has made a deus ex machina of natural selection since he neglects to dwell on the facts of infinite incessant variations.

Summary

CD pleased with Huxley for defending him against Sabine. Also pleased with much of Sabine’s address. Is sure JDH wrote the botanical part.

Suggests James Hector observe which insects visit endemic New Zealand plants

and JDH examine distribution of white vs coloured corollas in New Zealand.

Summary

More comments on "Insular floras": community of peculiar genera in the Atlantic islands descended from European plants now extinct.

Summary

First part of "Galapagos flora" ["Plants of the Galapagos Archipelago", Trans. Linn. Soc. Lond. 20 (1851): 163–233] finished but not printed.

Details of distribution of Galapagos flora. Peculiarity of island floras.

Leaves for Edinburgh on Wednesday.

Summary

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

Climbing plants: asks for more plants.

Summary

Forwards H. T. Stainton letter for reply.

Finds many Cucurbita have tendrils with sticking ends.

The "potentiality of so many organs in plants to play so many parts is one of the most wonderful of your discoveries . . . one day it will itself play a prodigious part in the interpretation of both morphological and physiological facts".

Is disgusted with Sabine’s address [see 4708] because of its mutilation of what JDH wrote.

THH’s slashing leader in Reader ["Science and ""Church policy"" ", 4 (1864): 821] – as usual he destroys all in his path.

Encloses letter from G. H. K. Thwaites with a message for CD [see encl].

Summary

Examining JDH’s list. CD struck by how many plants are common to Europe, S. America, and Australia.

Summary

"Throttled off" Welwitschia paper at Linnean Society [Trans. Linn. Soc. Lond. 24 (1863): 1–48].

Has read Tocqueville’s Democracy in America [1835–40] – disagrees with it. Tocqueville says democracy in America is a success. Democracy has persisted because there has been no cause for its overthrow (i.e., no struggle for existence, too much mobility).

Sends J. W. Dawson’s unsatisfactory letter.
