Summary

Account of Orchids.

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

Agrees Max Müller’s book [see 3752] is interesting but cannot see how it will further his "cause".

A book by J. W. Colenso [The Pentateuch and book of Joshua critically examined, pt 1 (1862)] has just appeared and will "make a noise".

Would like some observations made on Cypripedium.

Will not publish yet on Lythrum as he must make many more crosses; the mid-styled is fertile with half of its own stamens.

Would like to try a few experiments on tendrils.

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

Gives advice as to whether certain meteorological observations would be worth making.

Summary

CD is collecting [for Variation] all accounts of what some call "sports" and what he calls "bud-variations". He asks whether very slight variations in fruit appear suddenly by buds, or whether only rather strongly marked varieties thus appear.

Summary

Discusses politics in the U. S. and relations between Britain and America.

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!

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 Nesaea seeds for CD

and stamps for Leonard Darwin.

Summary

Forwards carbonate of ammonia and gelatine free of chlorine.

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.

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

Instinct in cats.

Summary

Would like to go to Cambridge [for BAAS meeting]. Reminisces about his student days.

Pleased that WDF likes his book [Orchids]. At one time CD agreed with Lyell that he was an ass to publish it.

Working on dimorphism and sensibility of other plants.
