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

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

Believes he gave JDH wrong address.

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

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

Bentham so impressed with JS’s paper that he is invited to become Associate Member of Linnean Society.

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

Requests climbing plants.

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

Summary

Inquires which nurserymen near Edinburgh cultivate coloured primroses and cowslips. Wants to repeat John Scott’s remarkable experiments.

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.

Summary

Sad about Oliver’s loss.

JDH’s reference to odd Begonia at same time as an article about it came out in Gardeners’ Chronicle [(1866): 313–14].

Is astonished that Pangenesis seems perplexing to JDH. Pleads guilty to its being "wildly abominably speculative (worthy even of Herbert Spencer)".

Summary

CD thinks JDH takes a hard view of Scott’s character, but will not argue further.

Leersia.

Working on homomorphic and heteromorphic crosses in Primula.

Summary

JS’s Primula paper was read at the Linnean Society and praised warmly by G. Bentham. Hooker was not present.

Summary

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

Summary

Forwards two character references for John Scott, for position JDH is arranging in India.

Summary

Is slowly writing Lythrum paper [Collected papers 2: 106–31].

Thanks for [Charles?] Wright’s observations on orchids

– could he note what attracts insects to Begonia and Melastoma? H. Crüger, who was going to observe Melastomataceae, has died.

Describes the climbing habits of Bignonia capreolata and Eccremocarpus scaber.

How does AG know the perfect flowers of Voandzeia are quite sterile?

He has a case of dimorphism in holly; asks AG to report on American hollies.

Summary

Much pleased by Edward Sabine’s address.

Grateful to HF for his interest [in the award of Copley Medal to CD].
