Notes criticising Max Müller’s views on language and Darwinism.
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.
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.
Returned last night. Huxley, left at Baden Baden, remarkably well.
Would like to come to Down with Strachey.
Starts tomorrow for visit to Farrer and Effie [Euphemia Farrer, daughter of Hensleigh Wedgwood]. Has not done such a feat [i.e., staying as a guest of someone outside the immediate family?] for 25 years.
Has been half killing himself with Drosera.
Discusses utility of plant secretions to ants.
Will read TB’s book when published [The naturalist in Nicaragua (1874)].
On inheritance of gesture.
Sends paper to be published in Sydney Mail on primitive man.

and remarks on the erection of human body hair, goose-skin, and the influence of colour and temperature on skin.

Reflections concerning the influence of cultivation (i.e., ploughing) upon variation.
Answers CD’s questions of 25 July [8987] about temperatures at which cold-blooded animals are killed.

Rejoices over Ayrton’s retirement. Hopes W. P. Adam, his successor, is a good sort of man.

Has observed CD’s points. Except for leaves of Nelumbium, would have supposed both wax and hairs were connected with absorption or respiratory functions. May subserve some function connected with rays of sun. Watering most prejudicial in the hot sun: a splendid subject for experiments.
