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.
Has found Lathyrus maritima on the cliffs near Barmouth.
Thinks THF has solved the mystery of Coronilla.
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.
Adam is a good man.

Thinks it would be worth while testing for electrical changes in the leaves of insectivorous plants.

Observations on bees’ biting holes in Lathyrus.
Suggests an experiment FD could carry out with Drosera.
CD is working on Mimosa, and "everything has turned out as perversely as possible".
Gives his opinion on why tubes of peas split to the right of the loose stamens [inLathyrus sylvestris].
No summary available.
Pollination and floral structure of Lathyrus. Asks where bees bite through the flowers.
Asks JDH to inquire of gardeners at Kew what they think about injury to plants from watering during sunshine. Wishes to experiment. He is already convinced that drops of water do not act as burning lenses.
