Summary

Orders J. B. Jukes’s Student’s manual of geology [1857] and Macmillan’s Magazine (Dec 1859).

Summary

News of K. E. von Baer’s support is magnificent – far outweighs Owen and Agassiz. Asks THH to tell Baer that a statement from him would be of utmost value.

R. Wagner [in an article on Louis Agassiz’s principles of classification, Göttingsche gelehrte Anzeiger (1860) pt 2: 761–800] "goes half way" between Agassiz and Origin.

Summary

Asks identity of [Henry] Fawcett, who wrote a capital article on the Origin in Macmillan’s Magazine [3 (1860): 81–92], "A popular exposition of Mr Darwin".

Summary

Gives the results of crossing experiments; some interesting and curious facts.

Summary

Auguste Bravard’s discoveries magnificent.

Bravard has sent pamphlets [Observaciones geológicas (1857) and Monografia de los terrenos marinos terciarios (1858)] with strange doctrine that Pampean deposit is subaerial.

Review of Origin by Wollaston [Ann. & Mag. Nat. Hist. 3d ser. 5 (1860): 132–43] clever and misinterprets CD only in a few places.

Wallace’s MS ["Zoological geography of the Malay Archipelago", J. Proc. Linn. Soc. Lond. (Zool.) 4 (1860): 172–84] admirably good.

Henslow "will go very little way with us". "He, also, shudders at the eye!"

Baden Powell says CD’s statement about eye is conclusive.

Leonard Jenyns cannot go as far as CD, yet cannot give good reason.

Summary

Thanks PLS for list of Galapagos birds.

Mentions note he will add to Journal [of researches (1860)]

and correction he will make in Origin [3d ed. (1861)].

Asks PLS about variability in "abnormal parts of birds".

Summary

Confirms CGBD’s impression given in a letter to J. S. Henslow that CD in the Origin did not touch directly upon the final causes of sexuality, which CD considers one of the "profoundest mysteries in nature". CD is inclined to stress sexuality as the means of keeping forms constant and checking variation although he grants its role in the origination of varieties. [See 2869.]

Summary

Has read MS of AM’s review [of Origin, read at Edinburgh Royal Society, 20 Feb 1860]; has no complaints. Has never heard of a hostile reviewer’s doing so kind and generous an action [as sending his MS for CD’s criticism?]. Sends some remarks on details.

Summary

Hopes to get Asa Gray’s review of Origin republished.

Argues for single origin of mammals.

Encloses two phylogenetic diagrams indicating possible descent of mammals.

Comments on rodents, marsupials, and dingo in Australia,

and on a paper on the survival of stumps as a result of root grafting.

Argues that man had a single progenitor and consists of a single species.

Comments on destruction of non-white races.

Summary

Admires Edward Forbes’s theory of continental extensions, but it will discourage investigation of distribution.

Mentions Oswald Heer’s proposed map of Atlantis.

Discusses extinction of plants caused by the glacial era. Migration of plants and animals during glacial period.

Encourages CL’s work [on Antiquity of man (1863)].

Comments on unfriendly reviews. Asks CL’s opinion about including a reply to reviewers in next edition of Origin.

Summary

Gradation in the eye.

Hooker intends to reply [to W. H. Harvey’s article in Gard. Chron. (1860): 145–6].

Discusses Aspicarpa with respect to correlation.

Comments on monstrous animals.

Discusses objections of Bronn and Asa Gray to natural selection. Cites parallel between natural selection and Newton’s concept of gravitation.

Mentions German experiments on spontaneous generation.

Summary

Comments on letter from Jeffries Wyman.

Discusses reprinting reviews by Asa Gray.

Mentions views of W. S. Symonds on the geological record.

Discusses descent of turtles and tortoises.

The universality of variation.

Notes only a few species leave modified descendants.

Discusses Apteryx.

Variation among pigeons.

Comments on fertility among hybrids.

Does not agree that he makes natural selection do too much work.

Summary

Discusses relationship between natural selection and more general laws. Law of gravity is not seen as requiring design. Mentions mathematicians’ judgment of probability.

Notes gestation periods for hounds.

Etty is somewhat better.

Mentions his paper on fertilisation of orchids by insects [Collected papers 2: 32–5].

Summary

Thanks THH for his lecture ["On the study of zoology", Lay sermons, addresses and reviews (1870), pp. 104–31]. Best exposé and classification of the higher objects of natural history he has ever read. On reading and observation.

Henrietta’s lack of improvement.

R. McDonnell’s work on rays and electric organs of fishes.

Summary

Sends copy of Origin.

Discusses stripes on hybrid of donkey and wild ass.

Will let ADB know if lady consents to sending rabbits to [Zoological] Gardens.

Asks about gestation of Canidae.

Summary

Has been able to do nothing in science of late due to illness [of Henrietta].

When JDD reads Origin, CD knows he will be opposed to it, but he will be liberal and philosophical, which is more than he can say for his English opponents.

Has not yet seen L. Agassiz’s attack, but in principle avoids answering.

No one understands Origin so well as Asa Gray.

At BAAS meeting at Oxford, CD’s side seems almost to have got the best of the battle.

Summary

Floral anatomy.

Wallace’s capital response on reading Origin.

E. W. Binney has published on coal-plants living in marine waters ["On the origin of coal", Mem. Lit. & Philos. Soc. Manchester 2d ser. 8 (1848): 148–94], an old CD idea.

Waste of pollen in horse chestnut will make a good case against perfection.

Summary
