Thanks AR for specimens of fruit.

Thanks CB for Transylvania [1865].

CD’s health has declined steadily. He must now be content to read about nature as described by CB and others.

Has just sent MS of Descent to printers. Recognises that [because of Franco-Prussian War] the publisher will have given up idea of a German translation.

Though the war is a misfortune for science, CD rejoices at the wonderful success of Germany; has met no one who does not share this feeling.

Thanks HS for a copy of his book [? Die Thierzucht (1868)].

Sympathetic to JVC’s views on Franco-Prussian war [see 7332].

Astonished at JVC’s readiness to begin work. Will send sheets as soon as possible. Has asked Murray to charge for stereotypes of 64 woodblocks at cost. JVC must make his own agreement with publisher.

Sends first four sheets [of Descent]. Murray charges £14 for the 64 stereotypes.

Cannot supply copies of woodcuts from Brehm’s Illustrirtes Thierleben [1864–9]. Hopes JVC’s publisher will be able to arrange to include them.

CD has already agreed that Julius Victor Carus will translate his next book.

Thanks JVC for his corrections. Will send other errata. Hopes to send remainder of vol. 2 [of Descent] in a fortnight.

Hopes German edition [of Descent] has not yet been printed because he has fallen into a most serious blunder [about sexual selection never acting on the young] on pp. 297–9 of vol. 1.

Corrections for Descent. Has sold 6500 copies in England.

Has finished rough draft of Expression, but will put it aside for the summer.

Will refresh himself with some curious observations on the response of plants to certain stimuli.

Thanks JVC for corrections for Descent. Index, which is too full, was hurried at the end.

Glad to hear of new German edition of Origin. He is revising the English edition, adding a new chapter of "Answers".

No new edition of Descent has appeared.

Would be glad to see a new translation of the Journal of researches, which he revised in 1845.

Comments on white colour of sea-birds.

Thanks HS for the preface to the 3d edition [of Die Thierzucht (1872)].

Has purchased H. von Nathusius’ work [? Vorträge über Viehzucht und Rassenkenntniss, Th. 1 (1872)]; feels he has ignored all that CD has attempted to make out with respect to domesticated animals.

CD offers to mark corrected passages in sheets of 6th edition of Origin.

Discusses question of hybrids between goats and sheep, on which H. von Nathusius has cast doubt in his recent Viehzucht [1872]. CD gives several references for a contrary view.

Asks JVC to inquire about HvN’s assertion that castrated rams have no horns.

Sends sheets [of the 6th ed. of Origin].

Thanks JVC for his letter about the sheep.

CD sends some sheets [of 6th ed. of Origin]. Informs JVC that he is having it stereotyped, so he can never again make any serious alterations. "The little strength left to me shall be employed on new works."

Will send second proofs of Expression.

Glad JVC has finished translating Origin.

Assures him that Mivart’s book [On the genesis of species (1871)] has produced a great effect in England and America. CD has discussed incipient structures at some length because it enabled him to give many cases of gradation.

Asks JVC to note that he does not vouch for Expression’s being worth translating.

Has sent sheets of Expression.

Thanks JVC for his History of zoology [Geschichte der Zoologie bis auf Joh. Müller und Charl. Darwin (1872)]. Considers the title one of the greatest honours ever paid him.

Reports on foreign orders for the heliotype plates of Expression.

Will consider JVC’s comments on Expression when he prepares a new edition.
