Review in Athenæum full of contempt. Is sure Owen wrote it [see 5931].

Gardeners’ Chronicle review [(1868): 184] favourable.

Fears Pangenesis is still-born. Cites Bates, Spencer, Lubbock, and Sir Henry Holland. Is sure Pangenesis will sometime reappear. Questions that are connected and answered by Pangenesis.

Offers to undertake publication of English translation of Fritz Müller’s Für Darwin. W. S. Dallas will translate it.

HM is certain his brother Fritz would like to see Für Darwin translated into English by Dallas. He will make arrangements with the German publisher.

Two friends are writing Darwinian works: Adolf Speyer on phylogeny of Lepidoptera

and August Röse on genealogy of mosses.

AG is writing notice of American edition of Variation [Nation 6 (1868): 234–6].

Pangenesis is "as good an hypothesis as one can now make".

Responds to CD’s queries on polygamy in birds and orang.

Discusses sexual selection and secondary characters; colours and sexual preference.

Expresses his admiration for Pangenesis; it is superior to Herbert Spencer’s theory.

ARW differs somewhat with CD’s chapter on causes of variability [ch. 22 in Variation]. Thinks several of CD’s arguments are unsound.

Briefly discusses how natural selection might aid in producing sterility between allied species.

Second issue [of Variation] is ready.

Murray thinks that the Athenæum review was written by J. E. Gray [see 5931].

Reports that when August Meyer confined several distinct species of Phryganeidae they coupled and produced fertile ova, indicating that some specific characters are not so important so far as reproduction is concerned [see Descent 1: 342 n. 2].

Has difficulty translating Piderit’s use of verbissen.

Will hold F. Müller’s book until CD decides about translating it.

AG is not surprised at popularity of CD’s Variation. Gives some corrections for next edition.

Is working on "Sexual selection"; asks WDF to send observations on birds’ finding new mates during breeding season [see Descent 2: 103–7].

Will forward LR’s memoir to Earl of Tankerville. Has sent LR’s pamphlet on "Darwin Lehre" [Die Grenzen der Thierwelt (1868)] to a German lady he employs as a translator. Cannot agree that there is an innate principle of perfection.

Thanks JM for presentation copies [of Variation]. Sends directions and list.

Has been told positively that hostile review in Athenæum was by Berthold Seemann, to whom he once refused a testimonial.

On the whole, reviews have been very good.

Will send English edition [of Variation] when available.

Mentions revisions in second issue concerning graft-hybrids.

Asks for Euryale seed for experiment.

Discusses fertility of crossed and self-fertilised plants.

Asks CD to make his queries about proportion of sexes more precise so he can keep them in mind in his experiments with silkworms. [see Descent 1: 313.]

Eight-year record of sexes of chickens.

Thanks for results on sexes of trout. [See 5793.] CD is collecting information about the proportional numbers of sexes in animals.

Is obliged for the facts about the hybrids [see 5910], which permit him to reject the view of B. D. Walsh (and H. W. Bates?) that organs play an important part in keeping incipient species distinct.

He has asked John Murray to send RM a copy of Variation.

Could not believe Owen to be so demoniacal as to write the Athenæum review [of Variation].

Gardeners’ Chronicle review [see 5918] is weak. CD’s ideas on causes of variation may be as hazy as the reviewer’s.

Huxley’s clever remark on Pangenesis. JDH’s view of Pangenesis as fundamental to development doctrines, but nothing is gained by formulation in terms of germs or gemmules.

Tries to answer question on last page of CD’s letter anent sexuality.

Finds no absolute differences in size of sexes of Copridae. Gives several other genera in which males are larger than females.

Confirms his view of stridulation organ of house cricket. [see Descent 1: 354–5.]

Tells CD of a powerful convert to Darwinism: H. von Kiesenwetter of Berlin.

On the pugnacity of male salmon during the spawning season.
