Does not think that publishing his letters as advertisement [for potato experiments] would help JT’s cause, so CD cannot give permission.

Regrets that he has neither the time nor health to undertake crossing experiments with JT’s specimens. Discusses crossing varieties.

Sends £25 subscription, though he is not a churchman.

Comments on Weismann’s remarks on the possibility of sexual selection in the genus Daphnia.

A. R. Wallace has published paper giving up sexual selection [Review of St George Jackson Mivart’s Lessons from nature, as manifested in mind and matter.] in Academy, 10 and 17 June 1876, pp. 587–8.]

Has received a baffling article on God, immortality, and socialism under a Darwinian point of view.

Clerk Maxwell has disagreed with CD on molecular calculations in relation to Pangenesis in Encyclopaedia Britannica article ["Atom", Encyclopaedia Britannica, 9th ed. (1875) 3: 36–49].

Complies with correspondent’s request; encloses photographs of himself.

Asks GHD to calculate average or mean heights of crossed and self-fertilised plant species.

Thanks FG for his report [on the statistical validity of CD’s experiments; see Cross and self-fertilisation, pp. 16–18]. Discusses FG’s comments, his own experiments, and the means by which the results may be analysed.

Obliged for Belfast Journal.

Almost impossible to determine what constitutes an individual. Definition for sexually reproducing organisms does not apply to lower ones.

Agrees to aid HA in applying for membership in a society.

Promises to vote for Lankester.

Acknowledges faults of R. L. Tait’s paper.

Sends congratulations and a teapot on the occasion of JT’s engagement.

Is pleased JT is not giving up on the spontaneous generation question. Feels strongly that subject will not be clear until it is understood how J. S. Burdon Sanderson and others succeeded in getting bacteria in infusions they had boiled for a long time.

Comments on her new book [A short history of natural science (1876)].

Declines invitation to accompany JJW to Crystal Palace.

Supports AN’s idea [of a natural history book for children].

Thanks RLT for his letter. CD took much trouble over his two cases [regrowth of amputated supernumerary digits, in Variation] but the evidence was shaky.

Sends some cash to help WED with moving expenses.

RLT’s two articles in Spectator [4 Mar and 25 Mar 1876] greatly honour CD.

Tait has made a good point about "Survival of the Fittest".

Dr Rudinger’s extensive inquiries show that all eminent German surgeons are unanimous about non-growth of extra digit after amputation.

J. Kollmann has written regretting CD has given up atavism and extra digits [in 2d ed. of Variation]; gives new evidence of a rudimentary sixth digit in batrachians.

Thanks for essay [Cras credemus: a treatise on the cultivation of the potato from the seed, having for proposed results the extinction of the disease (1876)] and seeds. Thinks principle on which JT is acting is right.

Cannot allow publication of his earlier letter [10368], as he cannot recall what he wrote.

McLachlan has as strong a claim to be F.R.S. as any entomologist, but Garrod’s work is of higher quality.

Thanks HB for obtaining a translation by a learned rabbi of [the Naphtali Lewy] letter – "a real curiosity". [See 10430.]
