Is sending chapter [of Earthworms] for FD to look over.

Comments on FD’s work on movements of mould.

Is glad to hear about Julius von Sachs and the circumnutation theory.

Summary

Commiserates on news of Wiesner and experiment on transmission of heliotropism. Asks whether he should review book for Nature.

Summary

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

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

Is sorry to have involved himself in a priority dispute between Wortmann and Elfving. Intends to publish on circumnutation; will CD send him his notes? Apologises for taking CD’s protractor, will send it back. Has met Oscar Schmidt.

Summary

Thanks FD for corrections [for Earthworms].

Discusses experiments on absorption in Drosera.

Summary

CD looks forward with dread to future as he does not have the strength to begin any new subject requiring much work.

Plans to look again at the absorption by roots and root-hairs.

Summary

Sends further chapters of Earthworms for correction.

Summary

Some papers have arrived for FD.

Comments on the work of Phillipe van Tieghem who evidently knows nothing of insectivorous plants.

Leslie Stephen’s visit to Down went off well.

Summary

Thinks FD should review Julius von Wiesner’s book [Das Bewegungsvermögen der Pflanzen (1881)]. CD comforted that Wiesner’s experiments support their findings but finds it laughable how differently he has interpreted them.

Summary

Discusses observations on circumnutation by FD, Kraus, Wortmann.

Summary

Would like some of his notes. Has been looking at roots of Linum, cucurbits, larch, and orchids. Is content that mother should teach Bernard whatever religion she likes.

Summary

Reports on a visit to Hermann Vöchting and discussion of Julius Sachs.

Summary

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

Summary

Tells some of his observations on root cells. Has thought of three good experiments to oppose Julius von Wiesner.

Summary

News from the laboratory at Strasbourg; is working on Equisetum roots. Wortmann has found circumnutation in the mycelium of a fast-growing fungus. Please send papers (see 13155).

Summary

Thanks FD for his excellent corrections [to MS of Earthworms].

Summary

Passes on an account from Cohen of preparations by Hahn of fossil coral-like structures.

Summary

Has taken almost all FD’s corrections for chapter six [of Earthworms]. Is glad FD approves of the book.

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.
