Sends extracts, from his forthcoming book [The naturalist in Nicaragua (1874)], about the secretion by plants of honey to attract the protection of ants. Invites CD’s comments.

Regrets he cannot receive JVC at Down on Monday as he would then be too unwell to travel on Tuesday, when he must leave for a visit [to Abinger Hall, according to the Journal].

Has been working hard on Drosera and Dionaea. His next book will be on these plants and not, as he had intended, "On evil effects of Inter breeding".

Thinks highly of GHD’s article [probably "On beneficial restrictions to liberty of marriage", Contemp. Rev. 22 (1873): 412–26]. A good omen for the future.
