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.

Thinking about HF’s paper on Plagiaulax [Q. J. Geol. Soc. Lond. 13 (1857): 261–82]. Owen might answer that all Purbeck mammals are marsupials.
Asks RP’s help in procuring a specimen of a real Irish rabbit, L. veomicule [Lepus vermicula]?.
HCW is trying to define what CD means by "variable" genera.
Comments on transport of ducks to Jamaica by hurricanes,
fish feeding on seeds,
and sterility of birds in captivity.
Describes problems of classifying species in highly variable genera. Lists highly variable genera. Comments on the list of Asa Gray. Says species may be made to appear more or less variable according to whether a genus is divided into few or many species.
Separation of sexes in trees [U. S.].
Do plants offer positive evidence for "continuous land" theory?
Protean genera.
Urges AG to generalise from his observations on the flora of the northern U. S.
Expected to find separation of sexes in trees because he believes all living beings require an occasional cross, and none is perpetually self-fertilising. The multitude of flowers of a tree would be an obstacle to cross-fertilisation unless the sexes tended to be separate.
The Leguminosae are CD’s greatest opposers; he cannot find that garden varieties ever cross. Could AG inquire of intelligent nurserymen on the subject?
Thanks AG for information on protean genera; much wants to know whether their great variability is due to their conditions of existence or is innate in them at all times and places.
Would rather not serve on Royal Society committee [for a North American exploring expedition]. Suggests subjects for geological investigation.
Ranges of species in large vs small genera: Asa Gray’s compilation fits CD’s expectation.
CD studies seedling mortality in his weed garden.
JDH’s work on Indian flora.
Sends account of his successful experiments in feeding wheat seeds to minnows.
