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.

Looks forward to reading CD’s statements about reflex action in Insectivorous plants.
Has prepared paper ["Physiology of the nervous system of Medusae", Rep. BAAS (1876): 158–63] in which he insists on occurrence of reflex action in absence of nerves. Would like to cite CD’s authority for occurrence of reflex action in plants.
Sends specimens of grafted potatoes. Describes grafting experiments designed to prove possibility of graft-hybrids, and thus, Pangenesis.
Sends successful graft-hybrid of red and white carrot.
CD should correct passage in Variation explaining deformation of sternum in fowls [Variation, 2d ed., 1: 287–8].
Chapter in Variation on Pangenesis is admirable.
Asks to borrow Ernst Haeckel’s Beiträge zur Naturgeschichte der Hydromedusen (1865) [and Zur Entwicklungsgeschichte der Siphonophoren (1869)].
Has not been neglecting Pangenesis for Medusae.
Would like to see papers [on potato grafting] mentioned by CD.
CD has doubtless seen case in Gardeners’ Chronicle of vine in which scion has affected the stock [P. Grieve, "Singular sport upon a grape vine", Gard. Chron. (1875): 21].
Returns papers [unidentified].
One on inheritance destitute of meaning. How can "force" act without any material on which to act? Discussion must assume truth of some such theory as Pangenesis.
