FD has sent proofs; nutating of Ricinus; Horace Darwin and the wormograph.
Sends letter and seeds from [F. J. Cohn].
Is working too hard.
His father asks him to thank TAE for sending the curious case of the insects [see 11271].
Thanks ASW for Aegilops seed.
Will publish Origin first
and then Descent.
AS is looking for a job in a zoological museum or accompanying an expedition.
Sends father’s regrets that CD will not be able to help Stecker as appointments are few in number and much sought after.
Suggests movements of sensitive plants may protect against insects.
JIR’s "theory" of sensitive plants published in an anonymous letter he sent to the Field 2½ years ago. Mechanisms for protection against insects in sensitive plants.
Julius von Sachs will "swear & curse" when he finds out he has missed sensitiveness of root apex. Has been putting his notes together and the case is conclusive. [Dated "Saturday 10th" by CD.]
Thanks for sending Nature; plans to leave on 22 May; anecdote about Bernard.
A report has arrived for FD which CD will forward.
Regrets that the arrangement to visit Down must be for Friday.

Asks whether canary grass and oats have chlorophyll in their cotyledons.
Has been working hard at circumnutation of leaves to see whether sleep movements are exaggerated circumnutation.
Suggests sensitive plants that close at night would be protected from nocturnal-feeding snails. JIR’s brother in India says snails occur there in abundance.
Thinks it would be a good idea to give the typing machine to Karl Semper.
Has been observing the movements of leaves and cotyledons; sleep movements are exaggerated circumnutation. Reports some odd observations on movement in Oxalis species.
Can send FD twisted branches of some climbing plants if he wishes.
Asks questions related to movement in plants. The cotyledons of Oxalis offer a promising field for study.
Wonders why Julius von Sachs thinks bloom is a protection against insects.
Encloses notes on the cotyledons of Oxalis species.
