Summary

Thanks for plants supplied from Kew.

On structure and function of leaf glands of certain plants.

Summary

Asks for identification of a Cineraria which is self-sterile.

Fritz Müller’s letter on Cecropia [see 10384].

Summary

Has been observing the movements of leaves and cotyledons; sleep movements are exaggerated circumnutation. Reports some odd observations on movement in Oxalis species.

Summary

Instructions to sow some seeds

and suggestions for experiment on effects of removal of bloom.

Likes Hugo de Vries very much; has hardly ever seen so modest a man.

Summary

Instructs FD to make some observations on movement in Trifolium and Impatiens. Sends some seeds to be sown.

Summary

Heliotropism nomenclature. Apheliotropic mustard roots grow more quickly in dark. Measures growth with microscope as S. H. Vines did in mould. Studying air roots.

FD’s and Stahl’s negative opinion of Sachs.

Summary

Believes that he will prove that the tip of radicle is the brain as far as geotropism is concerned.

Summary

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.

Summary

Can send FD twisted branches of some climbing plants if he wishes.

Summary

Discusses sleep movements of Porlieria.

Has read an abstract of Julius Wiesner on heliotropism and geotropism ["Die heliotropischen Erscheinungen im Pflanzenreiche", Anz. Kais. Akad. Wiss. Wien 15 (1878): 137–40] which seems important but is puzzling.

Gives details of his observations on climbing plants with reference to comments by Julius Sachs.

Summary

Has sent off Bulls Horn to Kew; has sent hamper to CD; is preparing drawings for his presentation at the Linnean Society; asks after William, and hopes to be able to come to visit.

Summary

Directs CD where to find tools in his room. Has been looking at agave and aloe flowers. Thanks family for their letters.

Summary

Will send corrected proofs [of Insectivorous plants].

Summary

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).

Summary

Has had a cold. Salvia hasn't come yet. Will look for orchids tomorrow. Will send off bull's-horn acacia on Monday or Tuesday.

Summary

Movement in plants: Philodendron and Dendrobium.

Will go to London on Thursday to receive Baly Medal. Laura Forster has offered them her house in London.

FD has sent proofs; nutating of Ricinus; Horace Darwin and the wormograph.

Summary

Forwards chapter [of Orchids (1877)] for correction.

Sadness at the death of Amy.

Summary

Lists the tasks he has completed; sends on letter from Romanes; news of Bernard.

Summary

Has given his reasons for believing that twisting of stem is related to circumnutation in Climbing plants.

Tells results of experiments on movement of cotyledons and radicles.

Is getting aerial heliotropic roots from Kew.
