Summary

Sends photograph.

THH wishes he could write the popular zoology but writing is a boring and slow process when he is not interested, and he is overburdened with lectures.

Summary

Lord Cardwell thinks it unlikely that Parliament will take any action on a vivisection bill this session. Playfair should be consulted.

E. F. W. Pflüger’s important memoir on how carbonic acid is produced by living matter and his speculation about origin of living matter [see 9931].

Summary

On THH’s Lectures to working men.

Work by Ferdinand J. Cohn on the contractile tissue of plants ["Über contractile Gewebe im Pflanzenreich" Abh. Schlesischen Ges. Vaterl. Cult. 1 (1861)] seems important. CD has come to the conclusion that there must be some substance in plants analogous to the supposed diffused nervous matter in lower animals.

[Part of P.S. missing from original.]

Summary

Will be obliged if Flower examines specimens. States questions he wants answered.

Summary

His note on the brain should be in small type.

Glad CD agrees with him on hand, foot, and skull question.

Has heard from Dohrn.

Summary

Thanks for Lectures on the elements of comparative anatomy [1864].

If Owen wrote article on "Oken" [Encyclopaedia Britannica, 8th ed.] and French work on archetype he never did a baser act [see ML 1: 246 n.].

Bad health lately.

Summary

THH rejects GGS’s charges. Chides him with possibility that if he substituted "Falconer" for "Busk" he might have done it also for "excluded" and "omitted".

Summary

Playfair "disgusted at our pronunciamentos against the Bill". Burdon Sanderson and William Sharpey agreed to it. THH feels he must serve on Vivisection Commission.

Summary

Has done nothing since 1 May. Slowly getting better under Bence Jones’s diet.

The Reader has been sold – would regret its failure as a newspaper for general science.

Pangenesis is recovering from shock it received from THH’s criticism.

Summary

BAAS Norwich meeting. Hooker [President] came out in great force. "Darwinismus" spread over the sections and crept into everything. CD will have rare happiness of seeing his ideas triumph during his life.

Summary

Thanks for 4th ed. of Origin.

What a basting CD gives "our mutual friend" [Owen].

Glad he argrees with THH on Jamaica affair [Gov. Eyre and the "rebellion"].

Summary

Thanks for three last lectures and the account of cirripedes.

Difficulty of classifying the higher groups.

Summary

Nearly agrees on contemporaneity, but THH pushes his ideas too far. Would require strong evidence before believing that the so-called Silurian, Devonian, and Carboniferous strata could be contemporaneous. Thinks THH’s case on advancement of organisation is strong. But he should read Bronn, before publishing again, and say more on other side. Cannot help hoping he is not as right as he seems to be.

Summary

Hooker admires THH’s review of Mivart [see 7977]. Most impressed by THH’s handling of metaphysics.

Hooker’s problems: family health and A. S. Ayrton [Commissioner of Works].

Summary

Thanks for THH’s address [to Geological Society, Q. J. Geol. Soc. Lond. 25 (1869): 28–53]. Admires it and enjoyed attack on William Thomson hugely, but would tremble if he were in THH’s boots. Distinction made by THH between evolutionists and uniformitarians is too great. CD’s sentences on age of world in Origin will do, but he might have been less timid had he read THH.

Summary

Haeckel wants British specimens of calcareous sponges. Can THH tell him to whom he can apply?

Health not improving – cannot climb even a hill.

Has heard THH’s article on Comte ["Scientific aspects of Positivism", Lay sermons (1870)] is a splendid success.

Summary

Enthusiastic about Lectures IV and V [Lectures to working men (1863)].

Sends specific comments on fantail pigeon,

sterility of hybrids,

the geological section diagram.

Summary

Thanks for [D. D. Cunningham’s] letter. Had hoped for a better haul but delighted to hear of the curious fossil.
