Summary

Has heard that Variation sold the whole edition of 1500 copies in a week [see 5844]. Has done him a world of good. Pall Mall Gazette has review which pleased him exceedingly [see 5874].

Summary

Thanks for JDH’s letter [3725].

Has become interested in experimenting on Drosera.

Observations on the ovaria of Cruciferae.

Summary

Is working one hour a day now, on illegitimate seedlings of Lythrum and Primula.

Begins to doubt John Scott’s accuracy about primrose and cowslip.

Does JDH believe in Karsten’s denial of parthenogenesis of Coelebogyne?

Summary

Has written recollections of Henslow [Collected papers 2: 72–4].

Summary

Thinks JDH is a bit hard on Asa Gray.

Bates’s letter is that of a true thinker. Asks to see JDH’s to Bates. Point raised in it is most difficult. "There is one clear line of distinction; – when many parts of structure as in woodpecker show distinct adaptation to external bodies, it is preposterous to attribute them to effect of climate etc. – but when a single point, alone, as a hooked seed, it is conceivable that it may thus have arisen." His study of orchids shows nearly all parts of the flower co-adapted for fertilisation by insects and therefore the result of natural selection. Mormodes ignea "is a prodigy of adaptation".

Summary

Reports on a séance. "The Lord have mercy on us all if we have to believe in such rubbish."

Asks JDH to vote for his nephew, Henry Parker, for Athenaeum membership.

Summary

W. H. Harvey’s dandelion case worth publishing.

Suspects the uniform Primula elatior JDH referred to is a distinct species.

Scott’s paper on Passiflora shows variability of reproductive systems.

Summary

Huxley has answered Kölliker in Natural History Review [(1864): 566–80].

CD is correcting two of Scott’s papers; is convinced primrose and cowslip are two good species.

Summary

Request for climbing plants.

Summary

Thanks JDH for Asa Gray’s interesting letter.

Would like JDH’s copy of Coral reefs. Needs it for corrections for a new edition. Cannot buy one.

Summary

CD has told Scott not to hope for help from JDH.

Health improving.

Hopes to write Lythrum paper soon.

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

Criticisms and comments on JDH’s "Insular floras" in Gardeners’ Chronicle [(1867): 6].

Summary

CD wishes he could sympathise with Asa Gray’s politics.

Orchids to appear soon.

Pre-glacial Arctic distribution.

Work on floral dimorphism.

High opinion of Buckle as a writer.

Summary

On effect of external conditions: CD thinks all variability due to changes in conditions of life because there is more variability under unnatural domestic conditions than under nature, and changed conditions affect the reproductive organs. But why one seedling out of thousands presents some new character transcends the wildest powers of conjecture.

Not shaken by "saltus" – he had examined all cases of normal structure resembling monstrosities which appear per saltum. Has fought his tendency to attribute too much to natural selection; perhaps he has too much conquered it.

Summary

"Climbing plants" sent off.

Encourages JDH to include notes on gradation of important characters in Genera plantarum or to write a paper on the subject. Has given prominence to gradation of unimportant characters in climbing plants. Believes that it is common for the same part in an individual plant to be in different states. Same may be true of important parts – for example position of ovule may differ.

Two articles in last Natural History Review interested him; "Colonial floras" [n.s. 5 (1865): 46–63]

and "Sexuality of cryptogams" [n.s. 5 (1865): 64–79].

Fact of similarity of orders in tropics is extremely curious. Thinks it may be connected with glacial destruction.

Leo Lesquereux says he is a convert for the curious reason that CD’s books make birth of Christ and redemption by grace so clear to him!

"Not one question [for JDH] in this letter!"

Summary

Doubts Decaisne’s report of larkspur self-fertilisation.

Enthusiastically observes climbing plants. Needs to know how novel his observations are. Finds R. J. H. Dutrochet has made similar observations, so he has wasted some time. [See Climbing plants, p. 1 n.]

Summary

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

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

Summary

Cannot see how J. W. Dawson can accuse JDH of asserting a subsidence of Arctic America. Much of evidence for subsidence during glacial period will prove false as it largely rests on ice action which is more and more viewed as subaerial.

Dawson is biased against Darwinism.

Suggests Greenland may have been repopulated after glacial period extinguished flora, by migration in sea-currents.

Max Müller’s view of origin of language is weakest part of his book [see 3752].

Would like to examine the rare Cypripedium hirsutissimum.

Summary

Acquired characteristics.

Huxley’s lectures: good on induction, bad on sterility, obscure on geology.

Asa Gray on slavery.

Falconer’s partial conversion.

Alphonse de Candolle on Origin.
