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 ACR for paper and comments on it ["On the denudation of South Wales", Mem. Geol. Surv. G. B. 1 (1846): 297–335].
Sends copy of South America.
Discusses action of the sea.
Criticises ACR’s views on sudden elevation of mountain chains.
Invites him to dinner on Saturday the 12th. Charles and Mrs Lyell, Edward Forbes, Richard Owen, and Thomas Bell coming also.
"Will you bring your map of S. America … and we will have a talk over it."
Asks ACR to establish height of Moel Tryfan in Caernarvonshire; "in my notice on this hill [""Ancient glaciers of Caernarvonshire"" (1842), Collected papers 1: 163–71] I give a very much less height than others". [See also another mention of the elevation of Moel Tryfan in "On the transportal of erratic boulders" (1848), Collected papers 1: 218–27.]
Thanks for report [on echinoderms, Ann. & Mag. Nat. Hist. 2d ser. 8 (1851): 1–19]. Wanted to learn about metamorphosis of the class. Agrees with THH’s distinction between individuals and zooids, but thinks zooids will never cease to be called individuals.
Testimonial for THH’s application for Chair in Natural History at Toronto.
Proposes to send THH vol. 1 of Living Cirripedia.
Offers to send Ascidia specimens of Beagle voyage. Describes some of them.
Hopes THH will review his book [Living Cirripedia, vol. 1] which has been published for a year with no notice taken of it except briefly by Dana.
Discusses Limulus-like larva. "I have become a man of one idea.– cirripedes morning & night."
On THH’s paper on cephalous Mollusca [Philos. Trans. R. Soc. Lond. 143 (1853) pt 1: 29–66]. Discovery of the type or "idea" (in THH’s sense, not Owen’s or Agassiz’s) is one of the highest ends of natural history.
Discusses anamorphism;
position of heart in Cleodora.
Variability within species;
cementing process in cirripedes.
Second Living Cirripedia volume published. Asks THH’s advice on presentation copies for continental naturalists.
THH’s review of Vestiges of creation in [Br. & Foreign Med.-Chir. Rev. 13 (1854)]. CD is almost as unorthodox on species as the author of Vestiges, but hopes not quite so unphilosophical.
Hopes L. Agassiz was sounder on embryological stages than THH thinks.
Agrees with THH on metamorphosis of branchiae of Balanus, and on his view of Owen.
Thanks for help on presentation copies of Living Cirripedia, vol. 2.
Suggests he examine cementing apparatus of Balanus.
Grief at the death of Edward Forbes.
Sends specimens of sessile cirripedes for corroboration of their cementing apparatus.
Absence of anus in Brachiopoda and Alcippe cirripedes.
Thanks THH for corroborating his observations. Discusses metamorphosis of ovaria to cement organs. Ovaries, germinal vesicles, and anatomy of cirripedes. Difficulties of classification, and observation.
THH’s article on Mollusca [Charles Knight, ed., English cyclopædia: a new dictionary of universal knowledge (1854–70) 3: 855–74].
Thinks J. O. Westwood deserves Royal Society’s Gold Medal. Asks THH’s opinion of his nomination. Lyell deserves Copley Medal, but, since he has Royal Medal, it may be objectionable to propose him.
Thomas Bell thinks John Lindley superior for Royal Society Medal. CD agrees, but demurs at Medal going to same branch of science two years in succession.
Perplexed about Albany Hancock’s qualifications compared with J. O. Westwood’s.
Death of H. De la Beche.
CL would like to put Joachim Barrande on the Royal Society’s foreign list. Of French geologists and palaeontologists, he is the man who has made the greatest sacrifices and produced the greatest results.
Approves drawing. No one who cannot draw should attempt to be a naturalist. Suggests corrections to [Lepas?] drawing. Comments on position of ganglia, cement glands, and stomach.
Responds to THH’s questioning of his observations on cirripede anatomy with extensive discussion of what he observed. Admits his elementary knowledge of microscopical structures but seriously doubts he has erred. Cement glands, ovarian tubes, etc.
Invitation to THH and wife to come to Down to meet H. C. Watson, T. V. Wollaston, and the Hookers.
