Thanks for JDH’s letter [3725].

Has become interested in experimenting on Drosera.

Observations on the ovaria of Cruciferae.

Asks his opinion of A. C. Ramsay’s glacial lake theory. Encloses Julius Haast’s communication on glacial phenomena.

Thanks for Haast’s observations. Particularly glad to get geological evidence of glacial action (in Southern Hemisphere).

Thinks Ramsay’s theory to large extent true, but thinks that in a much disturbed country some lakes would have been formed in depressions.

Encloses MS on observations and experiments on Drosera. JDH’s opinion will help him decide whether to pursue subject in some future year.

Thanks for opinion on Drosera. After working for a time on a subject he is absolutely incapable of judging its value.

Has found a case in Lythrum of a necessary triple alliance between three hermaphrodites; the strangest case of propagation recorded among plants or animals.

Asks for L. thymifolia to see how a trimorphic form passes or graduates into dimorphic.

Questions JDH on Linum perenne.

Has found 33 hybrids in one field between Verbascum thapsus and V. lychnitis. The perfect series of varieties would have justified running the species together, but every one of the intermediate forms is sterile.

Has sent two Impatiens flowers; curious to know what CD makes of the floral whorls and their vascular bundles.

Cassia is another genus that has different [coloured] anthers in same flower.

Continues to work on Welwitschia.

Feels as CD does about his work, which after a time seems flat and stale. He could never have done what CD did in his Orchids.

CD’s facts about Verbascum have horrible bearing on JDH’s practice of lumping species together.

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.

Does CD want Masdevallia?

Sends addresses of persons in S. America who would send Melastomataceae seeds.

Has ordered Matthieu Bonafous on maize [Histoire naturelle du maïs (1836)].

Has sent Masdevallia and other plants.

J. J. F. W. v. Parrot’s Ararat [(1834), trans. W. D. Cooley, in The world surveyed in the XIXth century, vol. 1 (1845)] refreshing in its simple faith in the ark.

Masdevallia turns out to be nothing wonderful, "I was merely stupid about it."

Asks for plants for experiments.

Hedysarum and Oxalis sensitiva seeds.

Asks whether Oliver knows of experiments on absorption of poisons by roots.

CD finds he cannot publish this year on Lythrum salicaria; he must make 126 additional crosses!

Asks for odd variations of common potato; he wants to grow a few plants of every variety.

Variation is crawling.

Has had some bad attacks lately.

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!

Requests reference to Jules Planchon’s monograph on Linum [Lond. J. Bot. 6 (1847): 588–603; 7 (1848): 165–86, 473–501, 507–28].

Sends list of seeds, including Oxalis, Boraginaceae especially Alkanna.

Asa Gray says JDH wrote reviews of Orchids in Gardeners’ Chronicle.

His experiments amuse him after dull day’s work on vegetables and fruit-trees.

Leschenaultia formosa has exterior stigma, thus eminently requiring insect aid, and thus ensuring crossing almost inevitably.

Asks whether Samuel Haughton at Dublin who made important medical discovery could be the same who reviewed Origin so hostilely [in Nat. Hist. Rev. 7 (1860): 23–32]; if so, he can sneer at and abuse CD to his heart’s content.

Asa Gray as rabid as ever [on Civil War].

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.

JDH admits he wrote Gardeners’ Chronicle and Natural History Review articles on orchids [Gard. Chron. (1862): 789–90, 863, 910; Nat. Hist. Rev. n.s. 2 (1862): 371–6].

JDH’s objections to CD’s idea of how Greenland was repopulated. Temperate Greenland has as Arctic a flora as Arctic Greenland – a fact of astounding force. Why should certain Scandinavian species be absent? Migration by sea-currents can no more account for the present distribution in Greenland than can special creation.

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.

Samuel Haughton was the prejudiced reviewer of the Origin. JDH’s opinion of SH.

Has heard from a W. African collector that P. B. Du Chaillu’s accounts [Explorations and adventures in equatorial Africa (1861)] are all false.

R. F. Burton has impudently stolen credit for Gustav Mann’s Cameroon expedition.

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.

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."

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.

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.
