Has offered Carl Semper the writing machine.
Speculates on the mechanism of movement in plants and their reception of and response to stimuli.
Considers Brown-Séquard’s discovery of inheritance of injury to nerves most important hereditary observation ever. Extremely interested in correspondent’s confirmation. Impressed that in reported cases of inherited injury suppuration tends to follow the injury.
Has been investigating nutational movements of climbing plants; comments on the opinions of Julius von Wiesner and Julius Sachs. Remarks on the sleep movements of certain plants and the mechanism of tendril curvature. Is experimenting with Porlieria.
Has visited K. G. Semper’s laboratory.
Is sending CD the seeds of a beautiful Cassia given to him by a friend. He sketched the unripe fruit a few months ago. This plant is rare in the area around Sta Catharina. He has found their largest and most beautiful butterfly Callidryas manippe near this tree and its caterpillars living on its leaves. Comments on how remarkable it is to find a species limited to living on a single tree in so large an area.
Thanks CD for his kind letter and accepts his offer of a writing machine.
Thanks CD for his condolences. Reminisces about their youth.
On the death of his naturalist friend, W. C. Hewitson.
Thanks for seeds
and information about earthworms.
Is working hard at movement in plants.
Does not think the Petunia is anything remarkable.
Notes Julius Sachs’s opinion on the heliotropism of moulds: he can see no use in the response.
C. E. Stahl is working on swarm spores which can be made both helio- and apheliotropic.
Sachs has told him that some ferns sleep, and he suspects that some grasses may move.
Sachs also feels they may be working at bloom from a wrong point of view and suggests leaves may need to keep dry in order to keep their stomata open.
Pleased CGS will accept machine.
Idea has struck him that might be of use to CD: that rapid changes during growth as in some plants and in insect metamorphosis may bear analogy to the slower changes resulting in the formation of new varieties.
Is forwarding the writing machine to Carl Semper.
Is glad FD has taken up his old friends, the twiners.
Hopes to get heliotropic aerial roots from J. D. Hooker. Asks FD to find out whether any moulds or roots are apheliotropic. Is puzzled by heliotropism in subterranean roots.
CD named corresponding member of the Royal Bavarian Academy of Science. [See 11634.]
Explains that it was his son, Grant, who sent JAA’s article defending Darwinian origins of morality.
Comments on CD’s Canadian admirers
and asks whether Grant may visit CD at Down.
Thanks for election as a Foreign Member.
Comments on function of bloom.
Describes the effect of water shortage on sleep movements in Porlieria.
Burdened with Anniversary Address to the Royal Society.
Quips that even Huxley is running out of speeches.
She and her father will not be idle working on worms for CD.
Change of address.
