Summary

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.

Summary

CD thanks Krause for the errata.

CD is sorry to hear that Krause’s part will not appear in the French edition, and cannot believe that C.-F. Reinwald would be influenced by antagonism to the Germans. Reinwald always gives CD a small percentage on sales, and CD had intended to pass it on to EK.

Summary

Problem with Charles Reinwald could be solved if CD would ask that French edition [of Erasmus Darwin] follow English. EK willing to co-operate with Reinwald.

Summary

Encloses a letter from CD to C.-F. Reinwald for EK to read, and if he approves, to send on.

Summary

Wants FD to find out what sort of man Ernst Krause is.

Summary

Geotropism.

Experimenting on Porlieria in damp and dry earth.

Hermann Müller has been ridiculed for teaching children "in the beginning was Carbon".

Will ask about Ernst Krause.

Summary

Thanks for FD’s letter describing microscopic work under experienced supervision.

Is glad to hear of C. E. Stahl’s objection to treating plants as mere machines.

Pleased that J. von Sachs has yielded on growth.

Perhaps Stahl will recognise whether the case of the silver fir is the same as that referred to in the German account [see 12074b].

CD has finished the first draft of his essay on Erasmus Darwin’s life and is "heartily sick of the job".

Summary

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

Discusses Müller-Thurgau’s work on heliotropism. Will start on Thursday for Heidelberg and Strassburg.

Summary

He has had no success with horse or Spanish chestnuts.

Summary

Notes observations on sensitivity and movement of radicles.

Has finished chapter [of Movement in plants] on sleeping plants and is now looking over heliotropism notes.

Is perplexed by Erasmus Darwin; Erasmus [A. Darwin] likes it, but Henrietta thinks it much too long.

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

Discusses the movements of radicles. His observations show that sensitivity to touch resides in the root tip and he believes that sensitivity to gravity governing geotropic responses is also in the root tip. Would much like to convert Julius von Sachs to his ideas on radicle movement.
