Summary

Two criticisms (one by Henrietta Darwin) of THH’s Lectures [to working men].

Summary

Has previously quoted details concerning the regrowth of her amputated extra digit in Variation [2: 14–15]. The case has since been disputed, so CD, who is revising his work, asks for some fuller details.

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’s efforts to obtain Copley Medal for CD fail. Thanks THH for kind words of sympathy.

Summary

Forwards a book [Horace Dobell, Lectures on the germs and vestiges of disease (1861)] and a genealogical table at the author’s request.

Summary

Has read Buffon; whole pages are like his own. But CD is not converted to non-belief. There is a fundamental distinction between Pangenesis and Buffon. Fears he may not resist publishing it, but will be cautious.

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

Comments at length on CL’s book [Antiquity of man (1863)]. CD is "greatly disappointed that you have not given judgment and spoken fairly out what you think about the derivation of species".

Lists large number of queries concerning minor points.

Praises especially the chapters on language and glaciers.

Comments on the temperature of Africa during the glacial period, especially with regard to the views of Hooker.

Mentions Owen’s paper on the aye-aye [Rep. BAAS 32 (1862) pt 2: 114–16].

Summary

Responds to the correspondent's comments on natural selection.

Summary

[On Antiquity of man] CD is "convinced that at times … you have … given up immutability". "A clear expression from you, if you could have given it, would have been potent with the public."

Objects to CL’s description of CD’s view "as a modification of Lamarck’s doctrine". Quotes Henrietta [Darwin]’s observations on this description.

Comments on CL’s controversy with Owen concerning the human brain.

The controversy between Falconer and CL.

The "wretched" review of CL [Antiquity of man, Athenæum 14 Feb 1863, pp. 219–21] and Huxley [Man’s place in nature].

Summary

Thanks HBD for his lectures On the germs and vestiges of disease [1861].

Thinks his reasoning that the V. M. F. ("force exhibited in the operations of life") is not a "given quantity" is satisfactory.

How far the conditions of life affect the forms of organic life puzzles CD more than any other part of his subject. Thinks he may have underrated its importance in Origin.

Asks for source of the quotation on regeneration in HBD’s work.

Summary

Has enjoyed FWF’s volume [Chapters on language]. Had found Max Müller’s theory obscure and weak.

Believes FWF would come to agree with him on species if he studied general questions in natural history. To argue for immutability of species on the basis of geology resembles a wise savage in a nation with no books saying his language has never changed.

Summary

Tells of a declaration and a subscription list to defend the rights of Bishop Colenso.

Summary

Discusses the Duke of Argyll’s article on the supernatural [Edinburgh Rev. 116 (1862): 378–97].

Has heard that the Incas married their sisters; this may be worth investigating as a case of inbreeding.

Summary

First impressions of Haeckel’s Generelle morphologie.

Has received THH’s [Lessons in elementary] Physiology [1866]

and reread Man’s place.

Asks THH to read revised "Hybridism" chapter in new edition of Origin. Hopes it will change THH’s view.

Convinced of P. S. Pallas’ view of loss of sterility under domestication.

Summary

Sends CD part two of his anatomical papers [Anatomical and physiological observations (1863) [part 1 (1854)]]; thinks CD may be interested in the paper dealing with variation in numbers of digits in man. Draws CD’s attention to another variation: the occurrence of a supra-condyloid process in the human arm.

Summary

Can understand EH’s feelings on death of his wife.

CD was impressed by manner in which species in South America are replaced by closely allied ones, by affinity of species inhabiting islands near S. America, and by relation of living Edentata and Rodentia to extinct species. When he read Malthus On population, the idea of natural selection flashed on him.

Agrees with EH’s remarks on Kölliker ["Darwin’sche Schöpfungstheorie", Z. Wiss. Zool. 14 (1864): 174–86].

Asks EH to thank Carl Gegenbaur [for Vergleichende Anatomie der Wirbelthiere (1864)].

Summary

Appreciates THH’s note more than Medal.

Encourages THH to write a popular treatise on zoology.

Sends Mrs Huxley a quotation from Tennyson, with sarcastic comment.

Summary

Lyell’s position on mutability.

Fertilisation of trees by bees.

Summary

Received JDD’s book [Manual of geology (1862)]

and pamphlet on man ["On the higher subdivisions in the classification of mammals", Am. J. Sci. 2d ser. 35 (1863): 65–71].

Fully admits JDD’s objections are valid. But is convinced of the general truth of his own views (with much incidental error), because they embrace so many phenomena and explain them.

Discusses some mistakes Owen has made;

Falconer’s disagreement with Owen ["On the mammalian genus Plagiaulax", Q. J. Geol. Soc. Lond. 18 (1862): 348–69].
