Is returning to Down.

Rejoices that GJR writes so much in Nature.

Summary

Comments on two letters received from W. F. P. Pfeffer [13425, 13464] who thinks Julius Wiesner’s view that light, etc. acts directly on plants is wrong.

Is frantic over the number of letters received about worms; feels the enthusiasm of the reception of Earthworms is laughable.

Is confounded by Euphorbia rootlets and has re-examined the effect of carbonate of ammonia.

Has thought of three good experiments to oppose Wiesner.

Summary

Asks him to visit.

Summary

Comments on GJR’s letter in the Times [25 Apr 1881] concerning vivisection. Mentions activity of anti-vivisectionists, G. R. Jesse and F. P. Cobbe.

Summary

Earthworms is selling well.

Discussed how to repeat some of their plant experiments while in Cambridge.

Comments on Julius Wiesner’s views on plant movement.

S. H. Vines was very much surprised at the action of carbonate of ammonia on the roots of Euphorbia.

Summary

Thanks for two letters from Pfeffer. Will return translation of Pfeffer and send a letter from Elfring. Looking forward to working on "antiWiesner" experiments. Will return on 26th or 27th.

Summary

Unable to contribute an essay to a symposium on the subject of vivisection. Objects to use of term "symposium".

Mentions articles of Hermann Müller.

Death of his brother Erasmus [26 Aug 1881].

Summary

Earthworm book with printer.

Has sent FM’s observations on paraheliotropism to Nature ["Movement of leaves", Collected papers 2: 228–9].

Plants with differently coloured anthers.

Intends gathering together his notes on "bloom".

Summary

All his advisers agree that CD ought not to take notice of Butler’s attack.

F. M. Balfour has offered to translate EK’s reply to Butler and to send it to Nature. [The letter was published in Nature 23 (1881): 288.]

Summary

CD tells how it came about that Anthony Rich bequeathed his house and land to THH.

Summary

Encloses letter from Elfving (not found). Should he publish on false circumnutation?

Summary

Discusses division of Trust. Is concerned Bessy’s portion will be smaller than Henrietta's. Had a pleasant visit in Cambridge. There is a clerical error in the division of CD’s property.

Summary

Thanks CD for sending Wallace’s book [see 13313]

and for writing to Hooker about FdeAF’s plants. Has written to Hooker to tell him of the plants he is sending and discuss the subject of the cypress trunks.

Thanks CD for his detailed instructions for suggested experiments.

Summary

Thanks LS for his advice and his kind note. When CD thinks how he has been treated he will say to himself "so good a judge as Leslie Stephen thinks nothing of the accusation".

Summary

Has sent FM’s account of Pandanus and Oxalis to Nature ["Leaves injured at night by free radiation", Nature 24 (1881): 459].

Is crossing heterostyled plants.

Hopes to get his notes on bloom together.

Summary

Progress of his and Frank Darwin’s work; "all natural science seems now to depend on section-cutting".

Summary

CD will soon finish corrections [of Earthworms] for printer, and then clean sheets will be sent to JVC for translation of the book and to Ernst Krause. The subject has been a "hobby-horse" with CD, and he has perhaps treated it in foolish detail. Has told Krause he does not think any part of the MS suitable for Kosmos, but Krause must decide.

Summary

Forwards a letter from W. F. P. Pfeffer, who opposes some of Julius Wiesner’s notions on plant movements.
