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

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

"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

CD very ill.

Suspects F. Boott’s widow is illegitimate granddaughter of Erasmus Darwin.

CD, like JDH, has speculated that agrarian weeds have become adapted to cultivated ground. Suggests comparison with country of origin.

Wallace’s praise of Herbert Spencer’s Social statics baffles CD.

[Letter completed by E. A. Darwin.]

Summary

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.

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

Recounts the trip back from St Petersburg – visits to botanic gardens and museums throughout Western Europe.

Pleased that CD admired Bentham’s address [see 6793]. JDH had read it in MS and modified some very heterodox passages about insularity. CD has hit the flaw in it.

F. A. W. Miquel is a convert.

Summary

The die is cast on Ayrton affair. Lord Derby has called for all of the correspondence, as a result of pressure by men of science on JDH’s behalf.

Has just had a Greenland collection, which supports his views altogether; "I am ready to do fight for these with you."

Summary

Health permitting, proposes to visit Kew on Friday.

Summary

CD’s illness.

The difficulty of getting John Scott to publish his work. Has sent Scott’s paper [on Primulaceae] to Linnean Society. CD is sure it is valuable.

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.

Summary

JDH’s opinion of Herbert Spencer.

Rejects CD’s view of inheritance of induced modifications.

Huxley grows fat.

Summary

Lyell’s volume [Principles, 10th ed.] received.

"We must now keep him straight anent origin and development."

Some of Spencer’s new part is interesting but much is dull and ponderous.

Huxley’s Elementary physiology [1866].

Has finished his New Zealand manual [Handbook of New Zealand flora (1864–7)]. New Zealand flora [and past geological conditions] suggest islands were once connected.

Speculates on the total amount of living organised matter on the globe, and whether it varies.

Balfour Stewart on sunspots.

Summary

Has finished long paper on "Climbing plants". Prefers sending it to Linnean Society if Bentham does not think it too long.

For New Zealand flora [1864–7] CD suggests JDH count plants with irregular corollas and compare with England.

Does not quite agree about Reader.

Is Tyndall author of piece on spiritualism?

CD’s illness diagnosed as "suppressed gout".

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

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].

Summary

JDH’s "shock" that CD was awarded the Copley Medal.

Oliver, Thomson and JDH independently concur mature tendrils of Dicentra are foliar, though JDH remembers they were axial in the spring. Expects he and CD were fooled, but will have to look again next spring.

Praises CD’s Lythrum paper [Collected papers 2: 106–31].

JDH completing F. Boott’s work on Carex [Illustrations of the genus Carex].

JDH now does suspect Mrs Boott is illegitimate daughter of Dr Erasmus Darwin [see 4389].

Summary

Introduces Ernst Haeckel.

Lyell sent same chapters to CD, who thinks them very good but is not convinced that changes of land and water will do all he thinks.

Summary

JDH and F. W. Binney identify Calamites specimens as pith casts. They are cryptogams related to, but higher than, Lycopodiaceae and contradict progression.

Insects found in coal.

Lyell says Stonesfield slate marsupials are actually placentals.

JDH reading Alexander Braun on individuality ["Das Individuum der Pflanze in seinem Verhältniss zur Species", Abh. K. Akad. Wiss. Berlin (Phys. Kl.) (1853): 19–122].

Summary

Thanks for Begonia and Oxalis.

Keeps obstinate about crossing and could argue till doomsday, but will not bother JDH.

Sees that JDH has finished Welwitschia.

Thinks Huxley’s Working Men’s Lectures excellent.

Has finished Linum paper [Collected papers 2: 93–105],

and abstract of Bates’s paper for Natural History Review,

and has begun to arrange concluding chapters [for Variation]. Is paralysed on how to begin.
