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.
Fears [CD’s] albumen theory will not work because albumen is coagulated and filtered out in making extracts of belladonna, hyoscyamine, and colchicine [alkaloid poisons].
Has investigated whether it makes a difference if extracts [of alkaloid poisons] are made from leaves, seeds, or roots.
Has discussed with E. E. Klein about the purchase of a Hartnack microscope from Paris.
Has found Lathyrus maritima on the cliffs near Barmouth.
Gives his opinion on why tubes of peas split to the right of the loose stamens [inLathyrus sylvestris].
Regrets that "our brush theory" is wrong.
FD has asked J. B. Sanderson about Mucin.
Reports that S. W. Moore may be able to provide various substances for CD’s research on the digestive power of Drosera (sundew).
He is travelling overnight by train from London to Pantlludw and will wake A. R. Ruck with a morningade on his flute.
Has got a cold, so will not go to Kew. Wrote to Hartnack about price of microscopes and describes own model. Told Hooker about Tisley Spiller’s microscope in Paris.
Observations on the leaves of Desmodium. Most are trifoliate; none has tendrils. Gives some comments from Hooker.
Describe the Pinguicula species found at Mürren. Have found seeds on some. Their large roots seem to indicate that they do not get much animal food.
Had two mornings working on Drosera but it was sluggish. Frog preparations are pretty good.
Asks DO to return enclosed post-card with locality of Genlisea aurea specimen that DO had sent.
Proofs arrived and Francis is correcting them. Tells Emma Darwin that Amy is delighted about the azaleas. The Ruck family very much like Isabella Bird’s Six months in the Sandwich Islands.
Will send corrected proofs [of Insectivorous plants].
Returns corrected proofs [of Insectivorous plants].
CD sends words that he is too busy to work on the Drosera RLT has sent. CD also regrets that the fluid on virgin pitchers of Nepenthes was not tested with white of egg. Until that is done, he doubts whether physiologists would admit the presence of the ferment.
Proofs have come. It will be jolly coming down to Southampton.
Sends thanks for CD’s help in making him a Fellow of the Linnean Society. Dyer has sent some Erinem.
