Cotyledon sleep movement in Haematoxylon.
Thanks for Forms of flowers.
Report of child with tail and man with four nipples.
Sexual selection, he thinks, must be left to others to settle. "Conscious" will be substituted for "voluntary" selection. Sound- and scent-producing organs attributed to "natural", not "conscious", selection.
Sends two papers on Roman ruins at Cirencester, which he asks CD to return.
Worm observations.
Has made out some of the functions of "bloom", which he outlines.
Further discussion of evidence for sexual selection. Prefers "conscious" to "voluntary" action. Distinguishes features that serve as charms and those that serve as challenges.
Thanks for another part of Australian orchids.
An example of inheritance confined to one sex.
Kind of JP to send notes on horses, but will not write on subject again.

In Descent [1: 12] CD discusses intoxication among animals. South African elephants reportedly eat a plant that makes them wild.

Thinks most monkeys would become habituated to alcohol if they could get it.
Sends a list of errata in Forms of flowers.
Has reread copy of Fritz Müller’s letter that CD sent some time ago and would like to publish the entomological observations in it.
Pleased with CD’s interest in temperance. Can he quote CD? Sorry the elephant story is a myth. It fits his argument for temperance: a passion for alcohol is natural [primitive]. Only the morally developed can resist. Moral development will take a long time. Thus education cannot cure alcoholism now. Thus public sale of alcohol must be outlawed. Although he is a follower of J. S. Mill and Herbert Spencer he has been forced to this conclusion.
Criticises passages of Insectivorous plants. Suggests plants be weighed before and after feeding to prove they have gained nourishment.
Notes the movements of leaves of Euphorbia jacquiniaeflora in response to light intensity.
Thanks RIL for notes.
Asks about movement of Euphorbia.
Is doubtful about the publication of Fritz Müller’s letter after so long an interval.
