Sends autograph. Hopes collecting will lead Bok to science, as it did him.

Thanks for letter expressing CD’s position with regard to experiments on living animals and for getting the letter printed in the Times [18 Apr 1881, Collected papers 2: 226–7].

Thanks for WTT-D’s attempts to get the Trifolium seeds.

Thanks for DM’s [Zoological atlas (1881)].

Copies of FD’s paper have arrived ["The theory of growth", J. Linn. Soc. Lond. (Bot.) 18 (1881): 406–19]. Does he want them dispatched?

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).

CD defends English physiologists on vivisection.

Sends his review of Movement in plants from Die Gartenlaube.

Comments on the future prospects of Kosmos.

Comments on review of Samuel Butler’s Unconscious memory by Romanes in Nature [23 (1880–1): 285–7] and Romanes’ reply to Butler [pp. 335–6].

Asks whether he might have a chapter of Earthworms to print in Kosmos.

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.

Thanks CD for R. W. Darwin’s memoranda respecting Franklin. Would be grateful for copies of any Franklin letters that exist among Dr Darwin’s papers.

Thanks EK for his article [on CD’s Movement in plants].

Admires EK’s wide interest in science. Would like to send him something to publish in Kosmos.

Fears his new book [Earthworms] will hardly do, but will send sheets when printed so that EK can decide whether any chapter or a part of one will serve. Victor Carus’s consent would be needed for publication in Kosmos, and CD will ask for it.

Ernst Krause wishes to publish a section of Earthworms in Kosmos. CD has consented. Hopes JVC will not object. He feels under obligation to Krause.

Sends £90 [for experiments on potatoes]. Sorry JT cannot get his varieties well enough known to ensure large sale.

Discusses the structure and formation of the Florida peninsula. Part played by marine animals in building banks on which coral can thrive.

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.

Discusses his investments.

Receipt, in CD’s hand, signed by JT, acknowledging subscriptions.

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

Discusses Ernst Krause’s publication of an extract from Earthworms translated into German in the journal Kosmos.

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.
