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.
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.
