Thanks for letter and seeds.
Asks that Hooker return references about plants eating insects.
Discusses Pinguicula.
Suggests experiments to try [with Nepenthes]. Asks JDH to test whether cabbage seeds and peas exposed to the ferment germinate.
Describes leaf movements of Pinguicula and Drosera in capturing prey. Notes effects of ammonium carbonate on leaves.
Describes how Pinguicula captures insects.
Thanks for letter on Erica tetralix.
Identification of leaves digested by Pinguicula.
Must stop work on "bloom" and leaf movements if he is ever to get anything published on Drosera, etc.
Sends thanks for seeds. Encloses memorandum in case WTT-D wishes to communicate information to Royal Horticultural Society. Has not time to prepare article.
Discusses condition of plants borrowed from Kew.
Thanks JDH for his "quite admirable" address [Rep. BAAS 44 (1874) pt 2: 102–16]. Suggests revisions.
CD thinks he is "now on right track about Utricularia" after wasting several weeks "in fruitless trials and observations".
Mrs Barber’s paper is very curious and ought to be published.
Thanks GB for his "Report on [the recent progress and present state of] systematic botany" [Rep. BAAS (1874): 27–54] and for the way in which he refers to CD’s book.
Thanks WTT-D for his present of Sachs’s book [Textbook of botany (1875)].
Asks for identification of a Cineraria which is self-sterile.

Does not think sermon by E. B. Pusey [see 11763] is worth a reply. HNR may quote CD as saying that Pusey is "mistaken in imagining that I wrote the Origin with any relation whatever to Theology". Pusey’s attack will be powerless to retard belief in evolution.
