Refers to "Devonshire Man"’s attack on him ["Professor Huxley’s last new theory", Pall Mall Gaz. 18 Jan 1870, p. 6]. His intention to answer – a waste, except for political bearing of Celt question ["Professor Huxley on Celts and Teutons", Pall Mall Gaz. 21 Jan 1870, p. 6].

Plans for his new book, Contributions to the theory of natural selection (1870), which will contain his papers on the subject.

Sends extract about a waterplant to illustrate CD’s points about the means of dispersal in geographical distribution.

Was gratified "beyond measure" by AN’s comments on his pigeon chapter [in Variation] in the [Zoological] Record [5 (1868): 94–6]. AN is the first man capable of forming a judgment who seems to have thought anything of this part.

Sends information on the distribution of various species in the U. S.

Asks who the gentleman is who is studying cattle skulls; RS has some that he would like examined.

Is glad to hear that CD is pleased with AN’s notice of his work on pigeons.
