Summary

CD will write to A. A. Gould for aid. Thanks for sympathy and assistance about chloroform.

Summary

Thanks for a suite of male and female specimens of Lepidoptera. Lack of difference in size of wings surprises CD; the female’s being smaller than male’s in early growth is new to him. Will ask a friend in India for comparable facts.

Summary

Is very glad CK wrote the article My Winter Garden (Kingsley 1858), which CD enjoyed.

Thinks CK should read abstracts of Living Cirripedia (1851) and Living Cirripedia (1854), and then, if he is particularly interested, borrow the actual volumes, rather than purchase them.

Summary

Requests WE’s measurements of tigers.

Asks about a work on domestic pigeons in an Eastern language. Will consult [Ayeen Akbery or, the institutes of the Emperor Akber, trans. from Persian by Francis Gladwin, 2 vols. (1777, 1800)].

Asks for specimen skins of domestic pigeons and poultry. [See Variation 1: 205.]

Summary

Likes JDH’s review of Alphonse de Candolle [Mémoires et souvenirs de A. P. de Candolle (1862)].

Falconer’s article on Lyell ["Primitive man. What led to the question?", Athenæum 4 Apr 1863, pp. 459–60] too severe.

CD has written a letter to the Athenæum "to say, under the cloak of attacking Heterogeny, a word in my own defence" [Collected papers 2: 78–80].

Bates’s Travels [Naturalist on the river Amazons (1863)] are excellent.

Summary

Encloses diagram illustrating difference between Chthamalus and Balanus. Specimens sent. Finds no Chthamalus in WT’s collection.

Has read with much interest WT’s book [The natural history of Ireland, vol. 1 (1849)].

Recommends E. S. Dixon’s book [Ornamental and domestic poultry; their history and management (1848)].

Summary

Has written to Hooker for his advice about the Darjeeling position. JS should not refuse the position on account of his experiments.

Summary

Lyell’s position on mutability.

Fertilisation of trees by bees.

Summary

JDH explains why he cannot take Scott on at Kew.

John Tyndall cannot answer CD’s questions on glaciers. Edward Frankland’s ignorance. In JDH’s opinion, heaviness of winter snowfall is the greatest element in size of glaciers and this is a function of low mean temperature. Discusses descent of glaciers.

Summary

Apologises for length of notes of advice for microscopic work.

Summary

When JDH goes to Germany, will he ask seed men if their marvellous true breeding lines are the result of selection.

Summary

Agrees with JDH on difference in grief over loss of father and of child. His love of his father.

The Reader.

Politics and science.

Health improved by Bence Jones’s diet.

[Dated "Thursday 27th" by CD.]

Summary

Criticises lecturing system in education and emphasis on classics. Has forgotten all his classical knowledge.

Asks JSH’s help in naming cirripedes, on which he is working. Believes he has made "some very curious points".

Expects a sixth child [Francis] in August.

Summary

Latitude overrules everything in distribution. Alpine distributions are like insular. Tabulating proportions.

T. V. Wollaston’s Madeira insects: many flightless, thus not blown to sea. TVW’s insects do not confirm Forbes’s Atlantis.

Summary

PGK’s letter stirred memories of their old days in the Beagle.

Gives news of his work on cirripedes. Would like to examine Scalpellum papillosum of King from Patagonia if PGK’s father has a duplicate in his collection.

Summary

Account of the birth of Leonard Darwin, during which he administered the chloroform to Emma.

Continues the water-cure.

Has begun work on fossil cirripedes.

Summary

Asks whether he can borrow from Joshua Alder an article [Sven Ludvig Lovén, "Ny art af Cirripedia Alepas squalicola", Ofers. Kongl. Vetensk. Acad. Förh. 1 (1844): 192–4] in order to have the plate copied. Asks to borrow additional specimen of Ibla.

Summary

Sends a list of "close" species from his Manual of botany.

Hopes Hooker or CD will write an essay on species. Discusses some of the difficulties of defining botanical species.

Summary

CD partly right. JDH was calling "stratification" what CD calls "foliation". Answers CD’s question on cleavage foliation in Himalayas. Glacial action.

Charmed by CD’s Admiralty instructions on geology [in Manual of scientific enquiry (1849), Collected papers 1: 227–50], but complains he does not give prices of books and instruments he recommends.

Summary

Sends an ammonite from the Upper Lias, which has Balanus-like bodies on surface. He wants CD’s interpretation. Discusses possible function of aptychi, siphuncular tube, and operculum in ammonites.
