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.
Encloses notes concerning his life and list of publications.
Returns the letters about primroses: they contain little that is new. Dr Bree’s is the best.
Bernard Quaritch interested in reprinting Primitive marriage.
Discusses digestion by insectivorous plants, asks JSBS to try same experiments using pepsin as the digestive agent to see how the results compare with CD’s observations on digestive power of Drosera.
Requests sewage water (and oleic acid) for experiments to determine sensitivity of leaves [of Drosera].
Reports on his examination of the effects of Drosera secretion on tooth enamel and dentine, and of artificial gastric juice on fibrous basis of bone.
Thanks him for copy of book [Der Kampf um’s Dasein am Himmel (1874)].
Sends the 1872 Report of the U. S. Geological Survey of the Territories, for which he was zoologist.
Most American naturalists support CD. His study of ornithology convinced him.
Lepus bairdii has a distribution limited to Yellowstone Lake.
No doubt CD knows of O. C. Marsh’s horse fossils.
Thanks for the sewage water and the oleic acid. The former does not seem to act.
Sends Edinburgh address so he may be sent sheets of Descent [2d English, for 3d German ed.].
Has a large class for his lectures.
Comments on his examination of slides [of milk casein?] sent by CD.
Surprised by CD’s finding that a drop of one per cent hydrochloric acid stops digestion of albumen by Drosera.
Descent [2d English ed.] will not be published until November. Will send JVC first sheet of revised proofs soon.
Pleased to hear of success of JVC’s lectures.
Summer plans have changed. Does not yet know when he will take a month’s holiday.
Sends his paper ["On secondary sexual characters in the Cheiroptera", Proc. Zool. Soc. Lond. (1873): 241–52]
and some of his observations of the gecko, which appear to contradict CD’s opinion.
"With kind regards, & many thanks for Prof. Steenstrup’s Photograph, which is most highly valued by C. Darwin"
Sends CD photograph of a "natural curiosity", a bear apparently "painted" with red iron on the face of a soft rock; has also sent copies to a few U. S. scientists.
CD responds to information about residue of milk digested by Drosera. Is obliged for information on strength of acids and albumen and now has little doubt acid had impaired the leaves. Awaits word on pepsin and papaw juice.
Thanks for note and paper ["Secondary sexual characters in Cheiroptera", Proc. Zool. Soc. Lond. (1873): 241–52].
Has corrected error in new edition of Descent [1874].
Sees nothing strange in geckos inhabiting frost-clad land and having no claws.
Regret at reading of Huxley’s death [a false report].
Sends CD provisional information that artificial gastric juice dissolves bone entirely and that gluten and fibrin are completely dissolved in hydrochloric, propionic, and butyric acids. [See Insectivorous plants, pp. 118–19.]
There is no uniform edition of CD’s work.
Thanks JSBS for his work. CD concludes the ferment of Drosera must differ from pepsin.
