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.

JDH’s report of Podostemon flowering cleistogamously under water in Bengal.
[Copious revision by JDH.]
He is steadily and very hard at work on "Variation" [Natural selection] and finds the whole subject "deeply interesting but horribly perplexed".
Questions JDH on separation of sexes in trees in New Zealand flora.
Thanks GB for information on apetalous flowers. "The whole order [Leguminosae] will remain my detestable enemies."
Is glad WBT is willing to describe the poultry CD can acquire. Sir James Brooke promises Borneo fowls.
CD is collecting all the evidence he can on natural crossing of varieties of plants. Asks readers of Gardeners’ Chronicle to give evidence "showing either that Leguminous crops, when grown close together do sometimes cross or on the other hand that they may invariably be grown close together without any chance of deterioration".
Thanks her for kindness. Announces, "We have now half-a-dozen Boys" [Charles Waring Darwin, born 6 Dec].
Grateful for Siebold’s wonderful facts [C. T. E. von Siebold, On a true parthenogenesis in moths and bees (1856), trans. by W. S. Dallas (1857)].
Vitality of spermatozoa.
Hybridisation of bees. Bees are in one respect his greatest theoretical difficulty.
CD still convinced about the relation of cement receptacles and ovarian tubes [in Crustacea].
Birth of C. W. Darwin.
CD is convinced of relation between separation of sexes and tree-habit.
Recent hard blows against crossing theory.
CD long tormented by land molluscs on oceanic islands; found transport possible experimentally.
Writes of arrangements for the end of the school-term.
Condition of Emma and the new baby [C. W. Darwin].
Pleased by what THH says on cement glands and organs in higher Crustacea. Content to be moderately right.
Hopes THH will dissect the Conchoderma.
Asks for cases of organs in which there is no apparent transition from other organs or in which transition can be shown in an unexpected way and for instances of odd and inexplicable connections between parts, such that if one part varies the other varies also.
Thanks for sending paper on geological development (Dana 1856). Discusses infertility of species. Discusses first part of Asa Gray’s paper (A. Gray 1856–7). Thanks for note on the Cave Rat. Discusses a new species of fossil cirripede, in the genus Chthamalus. Explains his interest in pigeon breeding.
Asks TD about variation among brachiopods.
W. J. Hooker thinks Harvey will be willing to give information on reproduction of higher marine plants.
On the variety of species definitions prevalent among naturalists.
