Summary

Health very bad. All scientific work stopped for 2½ months.

E. B. Tylor’s Early history of mankind [1865] impresses him.

Would like JDH’s opinion of last number of Spencer’s [Principles of] Biology [vol. 1 (1864)], especially on umbellifers. CD not satisfied with Spencer’s views on irregular flowers.

ED reports on CD’s health.

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

Doubts Decaisne’s report of larkspur self-fertilisation.

Enthusiastically observes climbing plants. Needs to know how novel his observations are. Finds R. J. H. Dutrochet has made similar observations, so he has wasted some time. [See Climbing plants, p. 1 n.]

Summary

Reread JDH’s letter "with infinite pleasure".

Plans to visit Kew.

Summary

Apologises that the house is full this weekend, but next weekend would be good.

Summary

CD has never doubted probability of Bering Strait land connection.

Family illness.

Summary

George Henslow’s curtness to JDH: "an attack of religion".

Embryonic leaves. Adaptive functions and taxonomic significance of cotyledons.

Asa Gray. Separation of sexes in U. S. trees.

Summary

Daughter Henrietta’s illness prevents a trip to London.

Summary

Yellow anthers of Heterocentron produce on the same plant thrice as many seeds as the crimson anthers. Crimson anther seeds produce dwarf plants, others rise high up. Monochaetum ensiferum facts are still more strange. Wants to investigate the case, and asks for a plant of the Melastomataceae just before flowering.

Has JDH a Rhododendron boothii from Bhutan with pistil bent the wrong way?

Summary

Congratulates JDH on receipt of Royal Medal.

CD gathering facts on aberrant genera of insects.

Summary

CD finishing Lythrum paper [Collected papers 2: 106–31].

Pleased at Bates’s appointment

and Wallace’s paper.

Summary

CD agrees cultivated plants may begin to vary after some time and then may vary suddenly, but cautions JDH on lack of evidence. His explanation is that small variations are ignored until they accumulate.

Summary

JDH’s letter to Wallace perfect. CD’s feelings about priority. Without Lyell’s and JDH’s intervention CD would have given up all claims to Wallace. Now planning 30-page abstract for a journal.

Observations on floral structure

and slave-making ants.

Summary

Thanks for letter of caution about Murray. He has offered to publish without seeing MS. CD thinks book will be popular to a certain extent. Lyell’s inducing Murray to publish Origin grates CD’s pride.

Summary

Pleased by JDH’s success. JDH gives argument for occasional transport with perfect fairness.

W. R. Grove’s address [see 5201] good, but is disappointed that species part was so general.

Summary

Does not understand JDH on Pangenesis: on last page he appears to admit all that he regards as mere words on previous pages.

Wallace admires chapter on Pangenesis.

Pangenesis is a comfort. CD gains no idea from words like "potentiality" or "diffusing an influence"; atoms and cells give a distinct idea.

A. Newton told George that Berthold Seemann wrote the Athenæum review

and that Lewis [Lewes] did not write the Pall Mall Gazette review [see 5874].

Summary

Must look after his wife, so is unable to come to visit.

Summary

Indignant over Owen’s conduct as described in Hugh Falconer’s article on elephants ["On the American fossil elephant of the regions bordering the Gulf of Mexico", Nat. Hist. Rev. (1863): 43–114].

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

Grieved by Falconer’s and Prestwich’s treatment of Lyell.

Reproductive anatomy of the common ash reminds CD of JDH’s Welwitschia because of its transitional forms.

Pleased JDH encourages Oliver to do orchids.
