Thanks RLT for his work, Diseases of women.
CD is also interested by RLT’s letter reporting a cat rearing chickens. "What a wonderful instinct is the maternal one."
Paralysis of the nervous system of Dionaea. Uses of tails of mice.
May publish a lecture on insectivorous plants and would like to dedicate it to CD.
Wishes to become an F.R.S.
Has found that H. G. Bronn in the chapter appended to his translation of Origin cited ears and tail of mice as facts opposed to natural selection. Suggests RLT examine hairs of tails of mice for possible nerves.
Has separated out a pepsin-like substance from the secretion of Drosera, which he proposes to call "Droserin".
Intends sending a paper containing some of his histological work [see "Freezing process for section-cutting; … staining and mounting sections", J. Anat. & Physiol. 9 (1875): 249–58].
RLT’s observations come too late, as CD’s book on Droseraceae has been printed.
Reports on his observations of ferment in secretions in Drosera rotundifolia and Drosophyllum.
Is waiting impatiently for the appearance of CD’s book [Insectivorous plants].
Insectivorous plants: the means and site of absorption of digested animal matter. [Newspaper clipping enclosed.]
Informs RLT of J. D. Hooker’s work on Nepenthes ["Nepenthaceae, Cytinaceae", in Prodromus systematis naturalis regni vegetabilis by A. P. de Candolle (1873), 17: 90–116].
Has asked JDH to try secretions of pitchers that had caught no insects.
An article on RLT’s lecture on insectivorous plants has appeared; the author adopts an anti-Darwinian attitude [see "Flower traps", Spectator 19 June 1875, pp. 784–5; RLT’s reply in Spectator 26 June 1875, pp. 816–17.]
Has read Insectivorous plants and is to review it for the Spectator.
Sends a note on the ferment of the Nepenthes secretion, which he asks CD to forward to Nature if he thinks it worth while [see "Insectivorous plants", Nature 12 (1875): 251–2].
CD returns MS of a paper by RLT. "If you have succeeded in separating the ferment, the fact is manifestly important." Asks whether RLT tested the digestive ability of fluid from pitchers without animal matter. This would be necessary to prove that there was ferment in the fluid. CD is glad to hear about the [passage?] for guiding insects; he had guessed this to be the case.
Insectivorous plants: observations on the digestive fluid of Nepenthes.
Reproduction of plant by "parthenogenesis".
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.
Digestive fluid in insectivorous plants. RLT’s work on tails.
RLT speculates on the "moral nature" of parental protection shown by humans and traces it back to its first occurrence in the animal world.
Wishes CD to present RLT’s paper on insectivorous plants to the Royal Society.
Thanks CD for consenting to present his paper.
