On the pugnacity of male salmon during the spawning season.
His translation and printing of Variation will be completed in two months.
His work on a relief committee for Russia’s agricultural distress has forced him to travel 1000 miles in the last week.
Plans to visit CD in July.
Trusts his paper ["Apterous Lepidoptera" (1867), printed for the West Kent Natural History, Microscopical, and Photographic Society] showed that he is thoroughly a disciple of CD.
Cites evidence that birds undoubtedly distinguish colours. [see Descent 2: 110.]
Thanks for corrections of errors [in Variation].
On the play of colours in the peacock’s tail.
On the proportion of sexes in salmon, trout, and rats. [see Descent 1: 305, 308.]
Thanks GGS for information on the peacock’s feathers. Asks whether the colour zones around the "eye" could result from varying the thickness of the film of colouring matter or whether it would require different kinds of colouring matter.
Does not understand JDH on Pangenesis: on last page he appears to admit all that he regards as mere words on previous pages.
Wallace admires chapter on Pangenesis.
Pangenesis is a comfort. CD gains no idea from words like "potentiality" or "diffusing an influence"; atoms and cells give a distinct idea.
A. Newton told George that Berthold Seemann wrote the Athenæum review
and that Lewis [Lewes] did not write the Pall Mall Gazette review [see 5874].
Crying in babies.
Proportion of sexes in insects, captured and bred. [see Descent 1: 313.]
Thanks CD for second issue of Variation.
Is glad CD is satisfied with his translation of Piderit.
Will not start on Müller [Für Darwin] until CD has communicated with the author.
Sends extracts giving details of the case of age-limited, hereditary blindness [see Variation 2: 78].
Recounts some cases of reversion that he has encountered.
Amazed that Hugo von Mohl and E. M. Fries are not foreign members of Royal Society; Thomson going over the whole matter.
Candolle’s contribution to botany.
Lubbock shocked about Wollaston.
CD’s answer to Greg was capital.
Comments on Variation.
Charles Murchison’s work on Falconer’s Memoirs [Palaeontological memoirs and notes of the late Hugh Falconer (1868)] and JDH on Falconer.
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.
