Has been reading JL’s address to the Entomological Society [Trans. R. Entomol. Soc. Lond. 3d. ser. 5 (1865–7): cxiii–cxxxi].
Would like to hear JL’s conclusion for or against Pangenesis.
Encloses information on sex ratios in thoroughbred horses.
Has looked through BDW’s papers and finds heaps of facts on sexual differences. Asks questions on sexual differences in particular species.
Mentions review [of Variation] in the Athenæum [15 Feb 1868, pp. 243–4].
Comments on adaptive utility of the right hand, an organ still undergoing specialisation.
Thanks for Nathusius [Die Racen des Schweines (1860)].
CD will call on JEG to hear his views on specific differences of pigs.
Does not know who has "cut me up so severely" in the Athenæum but suspects "your great man in the Museum" [Richard Owen].
JEG’s paper on pigs is being printed [Proc. Zool. Soc. Lond. (1868): 17–49].
Colouring in horses.
Sends data from J. G. Jeffreys on the form of shells of the sexes of Mollusca. [See Descent 1: 324, 326.]
Will gladly supply any information he can. Sends Registrar General’s reports; will inquire about the animals.
CD thanks BJS for photographs of Jemmy [Button]’s son
and for the curious case about stallions, which leads him to ask whether BJS has observed that horses when fighting try especially to bite each other’s necks.
Does he know anything about male seals fighting?
Asks for information on coloration and proportions of sexes in butterflies and moths for his work on sexual selection.
Wants to know how the colour of the eye of the peacock’s tail is produced, whether it depends upon colouring matter in the feathers or reflection, and whether any varying structural change will account for the series of colours surrounding it.
Proportion of sexes in spiders; coloration.
Has put question of proportion of sexes in insects to the Entomological Society. Quotes H. T. Stainton and F. Smith. Cites some cases mentioned by other members.
Is reading Variation; does not quite understand Pangenesis.
Discusses the flowers of, and cross- and self-fertilisation in, certain aquatic plants. Gives cases of dichogamy and perfect self-fertility.
CD in utter confusion about differences between J. O. Westwood and HWB on division of certain insects. Asks if HWB will homologise certain families for him, telling him which terms would be most generally understood.
Asks also about differences on sound-producing organs of Achetidae Gryllidae.
Encloses letter (not found) from Australian friend responding to CD’s queries on expression.

The Athenæum article [review of Variation, 15 Feb 1868, pp. 243–4] is a disgrace.
WSD will keep CD’s queries about Hemiptera in mind. Secondary sexual characters are certainly more marked in exotic than in British species.
Thanks EW for information [on expression] about Australians.
