Is much obliged that WBT will undertake tabulation of sex ratios in racehorses, greyhounds, and cattle.
Returns Anthropological Review.
Asks to borrow Desmarest on Crustacea [Considérations générales sur la classe des crustacés (1825)].

Does not know who has "cut me up so severely" in the Athenæum but suspects "your great man in the Museum" [Richard Owen].

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.
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.
Thanks EW for information [on expression] about Australians.

Thanks WBT for tabulation of sex ratios in racehorses.
Discusses factors possibly influencing the sex of caterpillars. Is gathering information on sex ratios in insects and would welcome any cases in which males seem to outnumber females.
RT’s argument about the Lasiocampa strikes him as very good; asks for any similar cases. Wonders whether male butterflies may serve more than one female.

Thanks HWB for bringing "the question of sexes" before the Entomological Society. Feels he will come to some conclusion by comparison of numerous observations.
It appears Pangenesis "will expire unblessed and uncursed by the world".
