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’s climbing plant experiments make it impossible to deny nerve force in plants.

Has discussed Frankland’s new glacial theory with Lyell.

Bishop Colenso’s trial.

Possibility of Scott’s coming to Kew as a curator.

Summary

Sabine’s address, printed in the Reader [4 (1864): 708–9], is good on the whole. Sends Huxley’s account of the row.

Praises John Ruskin’s eloquent reply to Jukes.

Summary

To Lyell’s chagrin, CD has come round again to A. C. Ramsay’s glacial theory.

On primrose and cowslip, CD maintains they are good species, notwithstanding Scott’s work.

CD defines species by power of remaining constant for a good long time and showing appreciable amount of difference from close species.

Summary

Reports on personalities at the Bath meeting of BAAS [Sept 1864].

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

Believes he gave JDH wrong address.

Summary

CD’s photograph looks like J. R. Herbert’s Moses in the fresco in the House of Lords.

JDH is delighted about oxlip, but hybridity does not explain some large patches that are uniform and do not vary towards either cowslip or primrose.

Encloses letter from W. H. Harvey discussing Myosotis sylvatica and the common dandelion.

Summary

Has found incipient stages of adhesive discs in Hanburia tendrils.

Huxley was probably right to have challenged Sabine, but the poor old man is sick.

CD remembers the old Disraeli novel [Tancred (1847)] that sneers at transmutation.

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

Again refuses to help Scott as "unfitted" to make his way in the world. Scott is unwilling to take his part in the "struggle for life", unlike Tyndall, Faraday, Huxley, and Lindley, who established themselves. Scott’s work is not science, but "scientific horticulture".

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

CD’s Lythrum paper has given him as much satisfaction as working out complemental males in cirripedes.

Response to award of Copley Medal.

Letters from Germany and France support natural selection.

Now that climbing plants are done, CD asks for Drosera.

Summary

Another plea to take Scott on at Kew. Emma begs CD not to employ him at Down.

Has just received a long article on the Origin from D. J. Brown, an Edinburgh baker [see 4464].

Summary

CD is not well enough to sit for Woolner.

Two Bignonia plants, which JDH does not distinguish as species, can be separated by differences in climbing and sensitivity behaviour.

Wants to write a non-quarrelsome reply to R. A. Kölliker ["Darwin’sche Schöpfungstheorie", Z. Wiss. Zool. 14 (1864): 174–86] in the Reader. Lyell opposes, but E. A. Darwin and Hensleigh Wedgwood support the idea.

Summary

JDH pursues the coffee plantation job for Scott.

Wrote 14 letters today. JDH’s work load.

Summary

Requests climbing plants.

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

Summary

Sends a Corydalis.

Hermann Crüger’s paper [see 4394] splendid, but he has made a mess of propagating Cinchona in Trinidad.

JDH’s opinion of Germans.

Summary

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

Health improving.

Hopes to write Lythrum paper soon.

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.
