Summary

CD pleased with Huxley for defending him against Sabine. Also pleased with much of Sabine’s address. Is sure JDH wrote the botanical part.

Suggests James Hector observe which insects visit endemic New Zealand plants

and JDH examine distribution of white vs coloured corollas in New Zealand.

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

Pleased that Bentham is cautious about Naudin’s view of reversion. CD can show experimentally that crossing of races and species tends to bring back ancient characters.

Suggests Gärtner’s Bastarderzeugung [1849] be translated

and that Oliver review Scott’s Primula paper [J. Linn. Soc. Lond. (Bot.) 8 (1865): 78–126] for a future issue of Natural History Review.

Is working on Variation.

Summary

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

Health improving.

Hopes to write Lythrum paper soon.

Summary

Rejoices that CD is beginning "the book of books", Variation.

Suggests that changes in colour of pollen, stigma, and corolla, as Scott reports in his Primula paper, may be related to changes in the insects required for pollination.

Supports Gärtner translation by Ray Society.

Comments on recent addresses by Lyell [Rep. BAAS 34 (1864): lx–lxxv], Bentham [Proc. Linn. Soc. Lond. 8 (1864): ix–xxiii], and Murchison [Rep. BAAS 34 (1864): 130–6].

Summary

Pleased with news of BAAS meeting

and Scott’s possible position as Thomas Anderson’s curator.

Suggests Wallace is due for a Royal Medal.

Agrees with JDH’s criticism of Lyell’s address [see 4614].

Bentham’s Linnean Society address treats continuity of life in a vague non-natural sense.

Rereading his old MS [Natural selection] CD is impressed with work he had already done.

Writing Variation much harder than Climbing plants.

Encloses request to JDH to propose, or suggest on his behalf, that the Ray Society publish a translation of C. F. von Gärtner’s Versuche und Beobachtungen über die Bastarderzeugung im Pflanzenreich (1849).

Summary

Requests climbing plants.

Asks that Oliver be told that he now does not care "how many tendrils he makes axial".

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

Asks JDH to verify an observation on Dicentra – what CD thought was a branch in the young plant now looks like a gigantic leaf in the old.

Concurs on Spencer’s clever emptiness.

Ramsay exaggerates role of ice. Sorry to hear that Tyndall grows dogmatic.

Admits difficulty of making case for Wallace’s Royal Medal at this time.

Will soon finish the first draft of Variation.

Summary

Morphological differences only partly define species; physiological differences, e.g., incompatibility results in Primula, are far more interesting.

T. Thomson’s review of Agardh’s muddled book ["Agardh’s classification of plants", Nat. Hist. Rev. (1864): 536–51].

Summary

JDH pursues the coffee plantation job for Scott.

Wrote 14 letters today. JDH’s work load.

Summary

JDH’s visit stimulates CD’s interest in his own work. Encloses list of queries on climbing plants. [Missing]

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

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

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

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

Request for plants.

CD’s continuing ill health.
