Comments on FD’s notions about movement of multicellular and unicellular organisms.

Comments on an interesting letter received from J. B. Hannay [see 13222] which leads CD to speculate on the possibility of organisms inhabiting a red hot earth under great pressure.

Comments on the response to Movement in plants, which seems to have been successful.

Is going over revises of Earthworms.

Is investigating further his notion that leaves align themselves in the rain so as to shoot off drops of water.

Has been reading Julius von Wiesner’s book [Das Bewegungsvermögen der Pflanzen (1881)]. Comments that it is "an excellent book, but he vivisects me in the most grievous terms, but most effectively".

Has been experimenting on aggregation of chlorophyll but with little success.

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.

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.

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.

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

Andrew Clark finds that CD’s heart is perfectly right.

Will stay until London until after the Linnean Society meeting unless CD wants anything. Asks to send abstracts of papers. Has made short abstracts of papers for Nature.

Hopes CD got telegram about Convolvulus. Is measuring plants every four hours. Will go to Brittany by boat from Southampton on Monday night.

Thanks for letter and journals. Sends information on earthworms and also information from Mr Ruck. Describes his fishing and his success finding sea shore plants that are new to him.

Sorry he forgot the gardener’s address. Having a very nice time in Cambridge, and is almost finished the bramble paper. Drawing room is upside down, so living in Horace’s working room and dining room. Greek question was lost in the Senate House. George dined there last night. Too muddy to bicycle. Has some stuff for spectacles.

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).

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.

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.

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

Glad CD approves of diaheliotropic paper. Reports on experiments with Carex and Yucca. Discusses translation of ‘Växtbook’ from Swedish. Heard some excellent music the previous night.

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

Discusses observations on circumnutation by FD, Kraus, Wortmann.

Reports de Bary’s opinion of Max Cornu. Accounts of various botanical experiments and observations.
