CD thanks him for his congratulations and for details of letters, which he will keep with the Butlerian documents.
FD is happy for his lecture to be republished in Kosmos.
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.
Reports on a visit to Hermann Vöchting and discussion of Julius Sachs.
Commiserates on news of Wiesner and experiment on transmission of heliotropism. Asks whether he should review book for Nature.
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.
CD asks him to say that the beautiful specimens of Dischidia arrived safely.
CD happy to lend Weismann’s pamphlet to RM.
FD and CD have been interested in AdeC’s diagram for illustrating inheritance. The difficulty of estimating different qualities in oneself and others is very great. Encloses a diagram illustrating how FD compares himself with his parents. CD has filled in a comparison with his father. It shows he resembles his father more than FD resembles CD. [The qualities compared are: stature, hair, eyes, pulse, musical capacity, ability to draw, tendency toward biological sciences, tendency toward mathematical sciences, perseverence, memory, aptitude for foreign languages.]
CD will be glad to keep the proof of the medal.
He is decidedly better again.
Sends quotation from Armand Trousseau, Lectures on clinical medicine [1868–72] 5: 213, on interruption of menstruation in young girls upon changing schools, as an example of the effect of changed conditions of life.
Sutton says monkeys often vomit, but cannot say whether they do it voluntarily.
Has been working with G. R. Crotch on stridulation. The sexual theory seems very shaky.
Is sending preparations of beetles.
Reports what he must pay for university courses. Forgets what CD wants to know about vermiform appendage.
