The Charles Darwin Collection
The Darwin Correspondence Project is publishing letters written by and to the naturalist Charles Darwin (1809–1882). Complete transcripts of letters are being made available through the Project’s website (www.darwinproject.ac.uk) after publication in the ongoing print edition of The Correspondence of Charles Darwin (Cambridge University Press 1985–). Metadata and summaries of all known letters (c. 15,000) appear in Ɛpsilon, and the full texts of available letters can also be searched, with links to the full texts.
Discusses his paper on mimicry and natural selection [Land and Water 9 (1871): 321]. Believes natural selection tends to fix mimetic characters rigidly.
Discusses the roles of natural and sexual selection in producing mimicry, and the problem of explaining the cause of the first mimetic variation; considers the ideas of A. R. Wallace and Fritz Müller on this problem.
Wishes to use some of Fritz Müller’s observations in his paper on mimicry.
CD’s reply and Huxley’s article ["Mr Darwin’s critics", Contemp. Rev. 18 (1871): 443–76] have answered all of Mivart’s objections to natural selection as applied to man.
A. G. Butler has named the specimens sent by CD with Fritz Müller’s letter.
Sends several facts relating to sexual selection, mimicry, and hybrids.
Discusses the possibility that mimicked and mimicking forms have descended from originally allied forms and have diverged in structure but not in appearance.
Gives some information on variation of ocelli between sexes in butterfly species.
Proposes publishing a series of papers on mimicry.
Encloses a copy of his paper on mimicry [Proc. Zool. Soc. Lond. (1873): 153–61].
Asks whether large variations are more often limited to one sex than slight ones.
Is doubtful about the publication of Fritz Müller’s letter after so long an interval.
Thinks the facts in Fritz Müller’s letter could be published.
Recommends August Weismann’s essay on dimorphism ["Über den Saison-Dimorphismus der Schmetterlinge", Studien zur Descendenz-Theorie 1 (1875)]
and has no doubt that intermediate forms could be eliminated as RM suggests.
Does not think Fritz Müller can object to anything RM has said in his essay.
Has alluded to colour preference among butterflies in Descent [1: 400–1].
Interesting article by Fritz Müller on sexual selection in butterflies, Kosmos [1 (1877): 388–95].
Thinks Weismann would welcome a translation.
Was dissatisfied with Wallace’s article.
Hopes RM finds a publisher [for his translation of Weismann’s Studien].
Good article by Fritz Müller in Kosmos supporting August Weismann’s views on caterpillars.
Is dispatching December number of Kosmos.
Will read the discussion on stridulation that RM mentioned.
Thinks there can be no objection to RM’s using a Fritz Müller letter [see 11319].
Thanks RM for his interesting paper ["Entomological notes bearing on evolution", Ann. & Mag. Nat. Hist. 5th ser. 1 (1878): 155].
Asks RM to send a copy of the Entomological Society’s Proceedings to Fritz Müller.
Thinks RM may like to see the enclosed [Fritz Müller letter].
Would like to have some insect photographs identified; they seem to show pretty and new case of protective resemblance.
Encloses Fritz Müller letter, which may be of interest [see 11463].
