Reports that the ability to move ears is common among the Sioux.

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.

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.

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.

Sends lists of earth [castings] made by worms [see Earthworms, p. 127],

and a catalogue of Australian Lepidoptera.

Thanks [FC] for his letter concerning a pony changing colour during the winter,

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

Asks THF to examine old flowers of Coronilla for holes bored by bees.

Is investigating whether drops of water injure leaves.

Encloses a copy of his paper on mimicry [Proc. Zool. Soc. Lond. (1873): 153–61].

Asks whether large variations are more often limited to one sex than slight ones.

Observations on effect of water on leaves.

Coronilla.

Further observations concerning the fertilisation of Coronilla by bees.

Reflections concerning the influence of cultivation (i.e., ploughing) upon variation.

Thanks MT for information on Drosera filiformis [see 8989].

Warns her against publishing statement about Drosera bending towards flies or meat that they have not touched.

Will send his book [Insectivorous plants] when published.

Answers CD’s questions of 25 July [8987] about temperatures at which cold-blooded animals are killed.

Doubts heat rigor was induced in Drosera. Gives his view of the relation of excitability to increase in temperature.

Suggests experiment to show that electrical changes in plant are the same as in animal muscle and nerve [see Insectivorous plants, p. 318].

Sends CD an excerpt from N. Y. Tribune [missing] about an account by W. D. Whitney, of Yale, of scientific work in Colorado.

Asks JDH why so many plants are protected by a thin layer of waxy matter or with fine hairs.

Wrote to John Smith for a plant of Oxalis sensitiva, but it has not acted well.

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

Thanks RM for his paper on mimicry.

Cannot answer RM’s query because he believes it impossible to define large variations.

Believes monstrosities are generally injurious and are not often, if ever, taken advantage of in nature.
