Thanks EW for information [on expression] about Australians.
Has read CD’s inquiry about proportional numbers of males and females born to domestic animals [see 5863] and outlines his theory regarding the factors determining the sex of offspring.
Found [Variation] full of interest. Has not yet made up his mind about Pangenesis; wants to hear what can be said against it.
Proportion of sexes in butterflies; discussion of subject at meeting of Entomological Society, London.
Attraction of males by female Lasiocampa quercus. [see Descent 1: 311–12.]
Sends a preliminary reply to CD’s query [5890]. Ten males to one female among captured micro-Lepidoptera. Six females to four or five males in those he has bred. HTS is aware this is diametrically opposed to information from [Alexander] Wallace and Bates, but the true proportion of sexes can only be ascertained by breeding.
Notes on sexual differences in British Hemiptera.
Is obliged for note on right-handedness. The subject is a very curious one, but CD has never attended to it and can give no additional facts.
