Summary

CD continues very ill.

His only work is a little on tendrils and climbers. Asks whether all tendrils are modified leaves or whether some are modified stems.

Last number [Jan 1864?] of Natural History Review is best that has appeared.

Summary

Proposes to support John Scott in research on relative fertility and self-incompatibility of plants. CD would pay him for a year or two but wants JDH to give him research facilities at Kew.

Summary

CD’s pleasure at JDH’s willingness to help Scott find a position in India.

Naudin underrates contamination of his experiments by insects. Thus CD doubts Naudin’s results on rapidity and universality of reversion in hybrids.

Wallace’s paper on man [see 4494] reflects his genius, although CD does not fully agree with it.

Summary

Thanks for Dawson’s letter. Doubts his evidence that climate of land was not glacial when upheaved after submergence.

Encloses memorandum of questions for C. V. Naudin.

Expression of the emotions.

Is building a hothouse for plant experimenting.

JDH’s ideas on America are more atrocious than his. What a new idea that struggle for existence is necessary to try to purge a government! Probably true. Slavery draws him one way one day, another the next. Yankees are "detestable toward us". Tocqueville.

Summary

Asks to borrow Botanische Zeitung (1860) with Friedrich Alefeld on Pisum [pp. 204–5].

JDH should ask George Busk whether he knows a better doctor than William Jenner "for giving life to a worn out poor devil".

Summary

John Scott has left Edinburgh Botanic Garden.

Asks JDH to ask Tyndall whether Frankland exaggerates the effect of snowfall on advance of European glaciers.

Huxley and Falconer squabble too much in public.

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

Sees difficulty of placing Scott at Kew. Suspects Balfour is prejudiced because Scott is a Darwinian.

CD’s former letter on Clematis [4403] blundered; work now being revised.

Summary

Comments on JDH’s list – very good, but Orchids and Primula paper have too indirect a bearing to be worth mentioning. The Eozoon is a very important fact and to a much lesser degree the Archaeopteryx. Müller’s Für Darwin [1864] perhaps the most important contribution.

CD has forgotten to mention Bates on variation and JDH’s Arctic paper ["Distribution of Arctic plants", Trans. Linn. Soc. Lond. 23 (1862): 251–348] in new edition of Origin.

Now finds that Owen claims to be originator of natural selection.

Summary

Falconer’s death haunts him. Personal annihilation not so horrifying to him as sun cooling some day and human race ending.

His health has been wretched.

Masters has written his agreement with CD’s "Climbing plants".

Summary

CD thought Watson’s article beastly in its criticisms of JDH. Watson’s criticism of CD was not new or important, but fair, so CD could honestly thank him, adding his regret at what was said about JDH.

Is sitting for Woolner bust.

Has read James Croll on alternation of glacial and warmer periods in north and south, which would remove JDH’s objections to cool period extending to equator.

Summary

Request for plant.

Receipt of Oliver’s letter.

Summary

On JDH’s suggestions for new edition of Origin.

Gray’s Atlantic Monthly articles to be published [in England] as a pamphlet.

Summary

Glad to hear Wallace is contender for Gold Medal. Has highest esteem for his extraordinary talents.

Thanks for H. Barkly’s letter from Mauritius.

Glad to see HB takes same view as CD about bones of deer [see 5395].

Objections to continental extension theory.

Progress [on Variation] very slow.

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

Responds to JDH on history of plant geography.

Opinion of Humboldt.

Origin of higher phanerogams.

Importance of the occurrence of south temperate forms in the Northern Hemisphere.

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

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

Notes on drops of nectar on sepals of cypripedium.

Summary

Is sending some plants and seeds to JDH.

Thanks Mrs Hooker for telling him of a life of his grandfather [Erasmus Darwin] of which he had not heard.
