Facts and inferences relating to different varieties of sweetpeas.

Extracts from botanical literature dealing with Dionaea, intercrossing, and sensitivity. [Bot. Ztg. (1833): 96; Thomas Nuttall, Genera of N. American plants (1818)].

Habits of ducks when sleeping on water.

Gives an extract from L. von Buch on the flora of the Canaries [Physikalische Beschreibung der Canarische Inseln (1825)].

Natural selection does not explain why animals of different groups in the same place often resemble each other.

Regrets he cannot answer SPW’s questions.

Discusses antiquity of subaerial volcanoes.

Disagrees "entirely & absolutely" with L. von Buch’s "elevation-crater-theory".

Agassiz denounces Origin as "atheistical";

AG is currently reviewing it [in Am. J. Sci. 2d ser. 29 (1860): 153–84].

Jeffries Wyman praises it, though not a convert.

CD asks how soon JM will go to press with Journal [of researches]; thinks he had better look it over to see if progress of science has made any correction necessary.

P.S. Asa Gray has written that Origin has caused great excitement in U. S. Agassiz has denounced it.

Will keep THH’s secret [of authorship of Times review of Origin]. It has made deep impression.

J. D. Dana’s illness.

Daily News accuses him of plagiarising Vestiges.

Returning Thomas George Bonney’s certificate, which it was a pleasure to sign.

Delighted that JH is interested in his book [Origin?]

Thanks CD for the Origin. WW is not yet a convert but there is so much "of thought and of fact" in what CD has written that "it is not to be contradicted without careful selection of the ground and manner of the dissent".

High praise and detailed comments on JDH’s introductory essay to Flora Tasmaniae, which CD has now finished reading.

Disagrees on power of transoceanic migration. Advocates glacial transport of plants.

CD’s response to reviews of Origin in Saturday Review [8 (1859): 775–6] and John Lindley’s in Gardeners’ Chronicle [but see 2651].

Notes by HCW on the Origin dealing especially with divergence and convergence. Believes there is some natural tendency to converge into groups in opposition to divergence generated by natural selection.

Praises CL’s work on human species.

A critical review of Origin in Saturday Review [24 Dec 1859].

A letter from J. G. Jeffreys criticises CD’s geological statements.

A note from William Whewell concerning Origin.

Has read Origin and considers it one of the most valuable contributions to present-day natural history. Believes, however, that there are difficulties in the extensive generalisation that all taxonomic groups are related by descent. Does not understand how Genesis is to be read unless at least the human species was created independently of other animals. Cannot bring himself to the idea that man’s reasoning and moral sense could have been obtained from "irrational progenitors": the "Divine Image" is the unsurmountable distinction between man and brutes. [See 2644.]

Remembers reading Smith’s memoir in Geological Transactions on the anomalous nature of Ventriuculidae. Asks for a copy.

Opinions on the Origin: AG thinks it masterly; Agassiz considers it very poor.

Discusses the possibility of "convergence" occurring; believes it could be only very limited.

Queries on expression among Fuegians and Patagonians.

WBC’s review [of Origin, Natl Rev. 10 (1860): 188–214] will do great good. It "turns the flanks of theological opposers" capitally.

Asks for information about cuckoo eggs and West Indian sheep.

Sends a copy of his Ventriculidae [of the Chalk (1848)]. This group, he feels, is well represented by CD’s plate of graduating species [Origin, ch. 4].
