Summary

J. S. Henslow’s defence of CD;

[Thomas?] Thomson’s opposition to Origin.

Summary

Comments on review of Origin by Andrew Murray [Proc. R. Soc. Edinburgh 4 (1860): 274–91] and views of William Hopkins on Origin ["Physical theories and the phenomena of life" Fraser’s Mag. 61 (1860): 739–52; 62 (1860): 74–90]. The attacks will tell heavily.

Mentions Blyth’s failure to receive appointment as naturalist to China expedition of 1860.

Encloses letter from Asa Gray.

Discusses gestation period in domesticated dogs.

Comments on hybrid fertility.

Summary

News of Etty’s health and of neighbours.

Pleased that JBI likes Origin.

CD never expected to convert people in less than 20 years, though now convinced he is "in the main right". Bishop of Oxford’s review made "splendid fun" of him.

Summary

Talks of getting copies of AG’s Atlantic Monthly articles for distribution in England.

Describes the pollinating mechanisms of Orchis pyramidalis and Spiranthes autumnalis.

Summary

Too ill to go to club.

Summary

Discusses Henrietta’s illness and their plans to return to Down.

Summary

Asa Gray’s articles in Proceedings of the American Academy of Arts and Sciences [10 Apr 1860] excellent; considering asking Athenæum to reprint them.

Summary

Etty [Henrietta Darwin] much improved.

Reference to his "hobby of striped asses".

Sceptical of JBI’s "curious stories" on spirit-tapping: "believe nothing one hears & only half of what one sees".

Summary

On the prospectus of Natural History Review. Suggests it might offer information on whether subjects that correspondents may wish to investigate have been done already.

Henrietta still very seriously ill.

Summary

To understand Leschenaultia pollination CD requires field observations in the native country.

Has observed two forms of cowslips, which he calls male and female. The same two forms are found in primroses.

Summary

Very pleased with Asa Gray’s letter to JDH [see 2638], which is "rich on Agassiz".

Summary

Dissection of Leschenaultia convinces CD insect agency necessary for self-fertilisation in this case.

Primroses and cowslips seem universally to occur in two forms. Very curious to see which plants set seed.

Summary

Agassiz is strongly opposed to Origin, but CD thinks K. E. von Baer may come out in support.

Discusses the possibility of favourable monstrosities in the light of Theophilus Parsons’ essay ["On the origin of species", Am. J. Sci. 2d ser. 30 (1860): 1–13].

Summary

Attacks [on Origin] are "hot and heavy". Adam Sedgwick and William Clark at Cambridge Philosophical Society opened a battery. J. S. Henslow defended in grand style.

Slow progress on bigger book.

Summary

Is puzzled what to think about the [Natural History] Review. Doubts that it is wise that JL and Huxley should give up time to it: "if it would stop your doing original work you ought not, even pro bono publico, undertake the new work".

Reports on Henrietta’s health.

The Quarterly Review [108 (1860): 255–64] quizzes CD "capitally" and he read it with thorough enjoyment.

Summary

Instructs JDH on how to pollinate Leschenaultia.

Evidence of Leschenaultia and the dioecious condition of cowslips and Auricula is making necessity of insect pollination "clear and clearer".

Summary

THH’s term "Pithecoid Man" is a theory in itself.

CD is convinced that his doctrine of a mundane period of glaciation is correct.

Henrietta’s serious illness.

Summary

Comments on his fear that "so many heavy guns fired by great men" might influence the public and scientists.

Sends CL the Owen-inspired Wilberforce review [Q. Rev. 108 (1860): 225–64].

Mentions defence of Origin by Asa Gray at American Academy of Arts and Sciences.

Agassiz and Theophilus Parsons have poor criticisms ["Prof. Agassiz on the origin of species", Am. J. Sci. 2d ser. 30 (1860): 142–54].

Lists other negative reviews by Rudolph Wagner ["An essay on classification by Louis Agassiz", Göttingische Gelehrte Anz. (1860) pt 2: 761–800], Charles Daubeny ["Remarks on the final causes of the sexuality of plants, with particular reference to Mr Darwin’s work On the origin of species by natural selection", Rep. BAAS 30 (1860) pt 2: 109–10], and two anonymous ones (one favourable).

Huxley says K. E. von Baer "goes a long way with us".

Comments on "pipes" in chalk as evidence of geological processes still at work.

Is writing on origin of dog breeds [Variation 1: 15–43].

Summary

Comments on CL’s advice not to reply directly to reviews.

Describes work on his Drosera manuscript.

Work delayed on his "larger book" [Variation].

Comments at length on the evolutionary significance of Robert McDonnell’s investigations ["On an organ in the skate", Nat. Hist. Rev. (1861): 57–60].

Summary

CD’s response to criticism of natural selection. Exasperated at not being understood. He tries to narrow the gap between himself and JDH.
