Asks to hear WBC’s conclusion about the Origin when he has read it all. Knows only one believer so far – J. D. Hooker. Sometimes feels frightened that he may be a monomaniac.

Curious about author of review of Origin in Athenæum.

W. B. Carpenter has written and sounds converted, as has Quatrefages [de Bréau], who will "go a long way with" CD.

Has been ill and thus had time to brood about reception of book.

Astounded she cares for his book [Origin] as much as she seems to.

Comments on variation among domestic dogs; believes domestic dog has descended from several wild species and those species from a single ancient ancestor.

Athenæum review is unfair.

Expects to convert four or five "really good judges".

Origin will be published 22 Nov. Fears correspondent will find the conclusions "abominable".

CD hopes Woodward was not the Athenæum reviewer. "The manner in which he drags in immortality, & sets the Priests at me … is base".

JDH has made CD feel he can "face a score of savage reviewers".

H. C. Watson has written to him in tremendous praise of the Origin.

Thanks CL for his decision to accept CD’s "doctrine of modification" [in Elements of geology, 6th ed. (1865)]. Believes it "morally impossible that investigators of truth, like you and Hooker, can be wholly wrong". Does not think CL’s decision will injure his works.

Thinks CL overrates importance of multiple origin of dogs.

Mentions sending copy of Origin to Herschel. Asks CL about Herschel’s reaction.

Mentions reactions to Origin. It will "horrify and disgust" TCE.

Some authorities approve more than CD expected.

Sales of Origin.

Discusses revisions for second edition. Mentions possible French translation.

Views of Quatrefages [de Bréau].

CD is astonished at sale of Origin [to booksellers].

Arranges to start new edition immediately. Cannot change much [while at Ilkley Wells], nor work rapidly because of health. Relieved that JM has no cause to repent of publishing Origin.

Murray has sold out Origin; wants a new edition immediately.

Asks THH to check whether Geoffroy de St Hilaire is correct [form of name].

Would be grateful for THH’s impressions on the truth of natural selection.

Discusses corrections for second edition [of Origin]. Will leave out the reference to whale and bear. Discusses pheasant crosses. Success of the book.

THH’s letter about the Origin makes CD feel like a Catholic who has received extreme unction. Can now sing nunc dimittis. Had determined to abide by judgment of Lyell, Hooker, and THH.

Problem of how variations arise at all troubles him also.

Rejoices over THH’s lecture ["On species and races, and their origin", 10 Feb 1860, Not. Proc. R. Inst. G. B. 3 (1858–62): 195–200] to be given at Royal Institution. Offers pigeon illustrations.

Adam Sedgwick has sent a "slashing" letter [2548] about Origin.

CD expected AS’s "strong disapprobation" of his book [Origin] but is grieved "to have shocked a man whom I sincerely honour". Has worked "like a slave" on the subject for over 20 years and is not conscious that bad motives have influenced the conclusions at which he has arrived. CD does not think the book will be mischievous and "if I be wrong I shall soon be annihilated". CD may have written too confidently from feeling confident that no "false theory would explain so many classes of facts".

Though many facts of palaeontology may be against his theory, CD begs JP to consider whether a theory wholly false could explain several classes of facts – which CD enumerates.

Sends references for materials useful for THH’s lecture.

Breeding and crossing. Pigeon fanciers.

Responses to Origin: A. C. Ramsay, Charles Kingsley, Quatrefages de Bréau.

Asks how many kinds of supposed birds’ footprints were found in North American sandstone.

Making progress on second edition of Origin.

Encloses letter from Adam Sedgwick [2548].

Mentions conversion of A. C. Ramsay.

Apologises for not having had time to read Phillips’ books.

Thanks CK for allowing him to insert his "admirable sentence" [in Origin, 2d ed., p. 481].
