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

Request for plant.

Receipt of Oliver’s letter.

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.

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

Sends CD West Ireland soundings.

More detail on his review "a la Lindley" [see 3797].

Bates’s paper ["Contributions to an insect fauna of the Amazon valley", Trans. Linn. Soc. Lond. 23 (1862): 495–566] is capital.

Andrew Murray’s article plays into CD’s hands through sheer ignorance.

JDH is on Royal Society Council.

Has no recollection of applying natural selection to Polynesians. None but a German would dig out such a passage if it exists [see 3812].

Has caused Tyndall to modify his pseudo-geology.

Has not seen Duke of Argyll’s review [Edinburgh Rev. 116 (1862): 378–97]. [The Duke] did not understand Orchids the least little bit, nor the Origin, when JDH saw him.

Summary

Strelitzia has arrived

but no books or bottles from G. H. K. Thwaites.

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

Strelitzia’s neat mechanism for exposing pollen.

Summary

On his deathbed her husband [Francis] expressed admiration for CD.

Summary

Returns books by Candolle and Robert Brown.

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

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

Summary

Mimosa too far gone to send now.

CD’s marjoram is the common [Origanum] vulgare, not the pot herb.

On the water injury, Thiselton-Dyer and he may have used too fine a spray, but plant is insensitive.

Horribly angry at P. G. Tait’s letter in Nature [8 (1873): 381–2].

Tyndall writes that he is strong – the next number of Nature will prove it.

G. Henslow is much better.

JDH leaves for Bradford [BAAS meeting] tomorrow.

Rejoices at CD’s success with Drosera; longs to be at Nepenthes.

Summary

Hermaphrodite trees are enough to "knock" CD down. Can JDH observe Eucalyptus to see whether pollen and stigma mature at same time?

JDH’s facts showing European plants are more common in southern Australia than in South America are disturbing because they are improbable on CD’s views of migration.

JDH said he would give examples of Australian forms that have migrated north along the mountains of the Malay Archipelago.

Summary

Thinks JDH would be wise not to touch on Pangenesis; it has very few friends. Bentham is doubtful, Carus against, and Alphonse de Candolle likes it least in the book. CD still convinced it will be hereafter looked on as "best hypothesis of generation inheritance & development". If JDH means to cut up Pangenesis he has no word to say in opposition.

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 complains of discomfort, but has not the strength for a project that would let him forget it.

Summary

On final instalment of "Insular floras" [Gard. Chron. (1867): 75]; rejoices at extent of their agreement.

Some criticisms of JDH’s position on geographical affinities, and volcanic islands.

Summary

At work on the introductory essay to Flora Tasmaniae.

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

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.
