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.
Thanks for Asa Gray’s letter, enclosed.
Knew JDH would not care about omissions but was vexed at his own forgetfulness.
Thanks for WT’s papers, especially ["The present aspect of the doctrine of cellular pathology", Edinburgh Med. J. 8 (1863): 873–97].
Examined the Cytisus and forwarded to Caspary. The C. adami case "gets more and more perplexing", asks for report if Cytisus purpureus-elongatus produces any pods.
Returns proofs of GH’s paper ["On hybridization among plants", Pop. Sci. Rev. 5 (1866): 304–13] with his criticisms. Prefers that GH not state that CD has read the proofs.
Does C. V. Naudin really say that ovules (not seed) of hybrid Luffa and Cucumis are imperfect?
Comments on CWvN’s Die Entstehung und Begriff [der Naturhistorischen Art (1864)].
Discussion of beauty of flowers in new edition of Origin not based on CWvN’s article.
Comments on CWvN’s argument that flower structures are not due to natural selection.
Thanks for Geological survey of North Wales [1866]. Longs to return to the mountains with which he was once familiar, but did not understand.
CD believes most strongly in reversion. J. G. Kölreuter’s, K. F. v Gärtner’s, and some of Charles Naudin’s cases leave no doubt in his mind. Forgets whether Herbert gave cases but in conversation he certainly believed in it. Thinks Gärtner is right to say reversion occurs only rarely in plant hybrids which have not been cultivated. [See 5120.]
Variation
Different forms of flowers of Rhamnus.
Thanks GM for a specimen; it is a sport with which he is already familiar.
Polymorphism in Rhamnus.
Polymorphic flowers of Rhamnus [see Forms of flowers, p. 294].
Has heard from B. J. Sulivan about the fossils at Gallegos, Patagonia. Would be a great haul for palaeontology if Duke of Somerset would encourage Capt. Mayne to collect them [on survey of Magellan Strait].
Tells JDH of a new map of world that he might use in his lecture [on "Insular floras", BAAS, 1866, J. Bot. Br. & Foreign 5 (1867): 23–31; Gard. Chron. (1867): 6, 27, 50, 75].
Impressed by H. Spencer’s last number, but each suggestion would require years of work to be of use to science.
Cuttings have arrived. Different flower forms [in Rhamnus?].
