RLT’s insectivorous plants paper.
The success of a recent lecture.
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.
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.
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.
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.
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.
Because CD has been unwell, he has not read RLT’s paper carefully, but it seems an important contribution to science. Hopes RLT’s chemical observations will be confirmed. It seems a great anomaly that two substances with an acid should be requisite for digestion.
Abstract sent to the Royal Society. It seems to CD "uncommonly clear and well-done".
