Sends his MS on Dionaea and hopes it may be useful for JSBS’s lecture ["On the mechanism of the leaf of Dionaea muscipula", Not. Proc. R. Inst. G. B. 7 (1874): 332–5].
Thanks for MS which he intends to read while on a week’s holiday.
Sends thanks for Francis Darwin’s offer of help and says that Francis’s experiments on digestion are complete.
Thanks for the careful experiments, particularly on organic acids.
Thanks for the acid digestion experiments, which can be printed as they are. CD trying Drosera on dentine and enamel.
Discusses digestion by insectivorous plants, asks JSBS to try same experiments using pepsin as the digestive agent to see how the results compare with CD’s observations on digestive power of Drosera.
Thanks JSBS for his work. CD concludes the ferment of Drosera must differ from pepsin.
JSBS’s article in Nature ["Venus’s fly-trap", 10 (1874): 105–7, 127–8] could not have been better done.
Has found another plant, Pinguicula, which can catch and digest flies.
Thanks for fibrin. Drosera and Pinguicula dissolve it thoroughly.
Has been testing the digestive powers of Drosera; wants to know whether a group of substances that elicit similar responses are related.
Discusses the powers of digestion of Drosera and why certain substances produce less excitement in the plant than others.
Sends results of experiments on digestion. Encloses two sets of notes: "Experiments on the digestibility of certain preparations sent by Mr Darwin" and "Note for Mr Darwin" [marked by CD for insertion in ch. 6 of Insectivorous plants].
Reports difficulties in experiments on digestion of fibro-cartilage. Asks about JSBS’s experiments with artificial digestive fluids.
JSBS must read Hooker’s address at Belfast [Rep. BAAS 44 (1874): 103–16] to see what a magnificent digester Nepenthes is.
