Sends comments and suggestions for Huth’s experiment on crossbreeding rabbits.

Examples of pupillary dilation.

Informs CD of Chauncey Wright’s death.

On fertilisation in certain orchids.

Writing article for a German newspaper on CD’s life. Requests autobiographical information.

Thinks CD’s case of twins with crooked fingers may be one from his twin study.

Asks whether the twins WO reported to CD [see 5470] were named Macrae. F. Galton has told him of a similar case with twins so named who inherited crooked little fingers from the maternal side [see Variation, 2d ed., 2: 240]. [The twins referred to by WO were actually his sisters, see 10170.]

Asks whether CD has observed that bees limit their visits to a single kind of flower on each journey from the hive, as Aristotle has said they do. What advantage would such a limitation be to the insects?

Sends a lecture CD wished to see

and corrects himself about the twins.

From Galton’s "twin study" he suspects that some progenitor of WO’s had the peculiarities in question.

Has collected cases of signs of assent for a revised edition of Expression.

Suggests bees visit same species because they know how far to insert proboscis and thus save time.

Sends CD the 2d part of his travels into the Tien-shan mountains [Erforschung des Thian-Schan Gebirgs-Systems (1875)].

Has written a paper on the ranges and systematics of wild sheep and on modifications probably resulting from competition with domestic sheep, which he wishes to translate into English and would like to see appended to Variation.

Discusses sexual selection in thrushes; it apparently modifies one species into another.

Reports on Schrankia aculeata in which pinna and pinnule are sensitive, but, unlike Mimosa pudica, rachis does not move.

Describes his own work on fossil flora of Eastern Siberia.

Discusses genus Ginkgo.

Comments on review [of Insectivorous plants] in New York Independent.

Working on Cross and self-fertilisation.

Asks CD’s opinion on whether there is a fundamental difference between the "primitive forms" of animals and plants. Mentions and rejects various views of major distinguishing characteristics.

Has secured rights to Variation from Judd & Co.; had to pay $350 [dollars or pounds!?] for old plates and promise 50% discount on 150 copies of the new edition. Hopes Murray’s charge for plates of new edition will not exceed cost of doing the work in the U. S. Judd lost out considerably from small sale of his edition.

Wishes CD to present RLT’s paper on insectivorous plants to the Royal Society.

Sends an article for CD’s opinion.

Has finished an account of the globes for the Philosophical Magazine ["On maps of the world", 50 (1875): 431–44].
