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

Sends further chapters of Earthworms for correction.

Summary

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

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

Thanks FD for corrections [for Earthworms].

Discusses experiments on absorption in Drosera.

Summary

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

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

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?

Summary

Describes seeds sent by George Payne [see 13205]. Is surprised that they bury themselves.

Summary

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

Summary

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

Summary

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

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

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.

Summary

Reports splendid cases of "paraheliotropism" which he now believes is one of the commonest movements of plants.

Summary

Dispatches chapters six and seven [of Earthworms].

Asks for any opinions on V. Hensen and his book, Physiologie der Zeugung [1881], which seems interesting.

Summary

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.

Summary

Ernst Haeckel wants to go to Ceylon to examine Medusae and Radiolariae, CD has offered him £100.

Is working on revises of Earthworms.

Has seen a pied flycatcher for the first time.

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

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