Purpose of bushy tails; their usefulness to their owners as a means of keeping warm.
Uses of tails of mice. Functions of tails generally.
Sends a short essay [The pathology and treatment of diseases of the ovaries (1874)] on which he would welcome CD’s opinion. Believes problems of pathology can be attacked by regarding them from "Darwinian" point of view.
Is preparing a paper on the umbilical cord ["On the anatomy of the umbilical cord", Proc. R. Soc. Lond. 23 (1875): 498–501; 24 (1876): 417–40] of which he sends a preliminary note [missing]. Believes spiral growth of the umbilical cord is important evidence of the descent of man; speculates on spiral growth in general.
Arrangements for a visit to Down.
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.]
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.
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.
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.
