Delighted by WBC’s letter about Origin. There is now "a great physiologist on our side". "You have done me an essential kindness in checking the odium theologicum in the E[dinburgh] R[eview] … immaterial whether we go quite the same lengths … the principle is everything."

Sends enclosure [unspecified].

Reminds THH to mention [German] translation [of Origin] when he writes to R. A. von Kölliker.

CD’s great satisfaction with JDH’s approval of Origin. The book has been extremely successful. Reactions of Asa Gray, Lyell, Bentham, and J. E. Gray.

Not one friend has noticed his pet bit in Origin: embryology.

Is preparing a reprint of Origin. Asks JL’s opinion on the book’s merits; values his judgment.

Local affairs and finances.

Suggests HF investigate hippopotamus tooth.

Has heard HF is very antagonistic to his views on species. Cannot believe a false theory would explain so many classes of facts.

Delighted JDH coming to Down. They will discuss Origin. JDH’s remarks that theory explains too much are excellent, yet CD cannot see his error.

Received JDH’s introduction to Flora Tasmaniae.

Criticism of C. V. Naudin’s descent theory.

Asks that Lyell be allowed to see letter.

Much pleased that LH approves of Origin.

"Ilkley [Wells] did me extraordinary good."

Wants to know C. J. F. Bunbury’s opinion of Origin.

CD will not write to L. Descaisne to defend his priority over C. V. Naudin.

Feels success of theory depends on acceptance and application by good and well-known workers, like JDH, Huxley, and Lyell.

High, detailed praise for introductory essay to Flora Tasmaniae [reprinted as On the flora of Australia (1859)]. CD expects it to convert botanists from doctrine of immutable creation.

CD has written to Asa Gray criticising J. D. Dana’s arguments for a warm period subsequent to glacial period.

Remembers it is Alphonse de Candolle who states that many species are not true species.

Did Huxley write the excellent review in the Times?

Queries possible misprint in JDH’s introduction to Flora Tasmaniae.

Thanks for correction concerning the scarcity of fossil littoral shells.

Grieved at JDD’s illness. Recommends water-cure. Describes his own illness.

The reception of Origin has been more successful than he dreamed.
