Summary

Appreciates CD’s acknowledging his letter and his comments on Acropera. Will send CD the Acropera capsule which is now maturing.

Experimenting on vegetable parthenogenesis.

Structure of Acropera.

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

Discusses primrose ovules,

Atlantis paper [Nat. Hist. Rev. (1862): 149–70],

plant migrations;

Corydalis.

Summary

Thanks JHB for specimen of Corallorrhiza;

would like some seeds of Corydalis claviculata.

Summary

Sends Asa Gray letter: "nearly as mad as ever in our English eyes".

Bates’s paper is admirable. The act of segregation of varieties into species was never so plainly brought forth.

CD is a little sorry that his present work is leading him to believe rather more in the direct action of physical conditions. Regrets it because it lessens the glory of natural selection and is so confoundedly doubtful.

JDH laid too much stress on importance of crossing with respect to origin of species; but certainly it is important in keeping forms stable.

If only Owen could be excluded from Council of Royal Society Falconer would be good to put in. CD must come down to London to see what he can do.

Falconer’s article in Journal of the Geological Society [18 (1862): 348–69] shows him coming round on permanence of species, but he does not like natural selection.

Sends Lythrum salicaria diagram.

Summary

Now believes flowers of Fumariaceae must be self-fertilised.

Planning a piece on dimorphism in the Natural History Review ["On the two forms, or dimorphic condition, in the species of Primula … by Charles Darwin", n.s. 2 (1862): 235–43].

Observations on Campanula dimorphism.

Summary

Comments on HF’s paper on Plagiaulax from the Purbeck beds. Paper "dreadfully severe" on Owen.

"I am worse than ever in bearing any excitement."

Glad HF attacked Australian Mastodon. Never did believe in him.

Mentions Primula paper [Collected papers 2: 45–63].

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

Sends CD a Chinese breed of guinea-pig. Has heard it claimed that the domestic guinea-pig will not interbreed with the wild rock cavy and that, therefore, artificial selection has formed a new species.

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

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

CD has been experimenting on the fertility of peloric flowers, with the forlorn hope of illustrating sterility of hybrids; seeks further plants or seeds.

Summary

Relates death of H. G. Bronn.

Discusses publication of German edition of Orchids [1862].

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

Asks for information about peacocks, especially Pavo nigripennis. Suggests a crossing experiment.

Summary

Asks for information about japanned peacocks from Hudson [John Henry?] Gurney’s flock.

Summary

Is pleased that AdeC is interested in the Primula case ["Dimorphic condition of Primula", Collected papers 2: 45–63]. Is pursuing analogous experiments on other plants and on seedlings raised from the unions.

CD’s "large work" progresses slowly owing to ill health and his work on Orchids.

CD is not surprised that AdeC is unwilling to admit natural selection – "the subject hardly admits of direct proof or evidence. It will be believed in only by those who think that it connects & partly explains several large classes of facts".

Hopes AdeC will publish on Quercus

and rejoices that he intends to return to the study of geographical distribution. No one can claim to have read AdeC’s truly great work on that subject [Géographie botanique (1855)] with more care than CD.

Summary

Thanks for JDH’s letter [3725].

Has become interested in experimenting on Drosera.

Observations on the ovaria of Cruciferae.

Summary

So JDH did write the Gardeners’ Chronicle review [of Orchids]! CD guessed it from the little slap at R. Brown.

Dawson’s lecture has nothing new. Absurd to assume Greenland under water during whole of glacial period. Suggests absence of certain plants in Greenland due to seeds not surviving in sea-water. Suggests an experiment on vitality in sea-water of plants that might be in Greenland. Is more willing to admit a Norway–Greenland land connection than most other cases.

Urges JDH to warn Tyndall on his glacial theory of valleys in Switzerland.

Is working on cultivated plants.

Summary

Stupefied by CD’s five forms of Lythrum.

Asa Gray busy with Cypripedium. JDH offers some to CD if he wants to challenge Gray.

J. W. Dawson’s review of JDH’s paper on Arctic plants.

Louis Lucien Bonaparte’s views on Basque and Finnish language [Langue basque et langues finnoises (1862)] suggest to JDH that Basques are Finns left behind after the glacial period, like the Arctic plants!
