Thanks FD for corrections [to Orchids (1877)].

Thinks Johann von Fischer’s paper on monkeys’ rumps [Der Zoologische Garten 17 (1876): 116–27, 174–9] worth translating, and he intends to write a letter on it to Nature [Collected papers 2: 207–11].

Sends an article for FD.

Is glad he is able to work on his teasel paper [Proc. R. Soc. Lond. 26 (1878): 4–8]; suggests some observations FD could make.

Asks for reference to an article on a mandrill.

Has seen notice on Empetrum but cannot understand how leaves in bud could act as fly-catchers.

Asks for details of dimorphism in Sethia from Thwaites, Enumeratio plantarum Zeylaniae [1864]. [See Forms of flowers, p. 122.]

Asks FD to mollify Daniel Oliver and assure him that CD asks "only for what I wd. give my life’s blood for".

Asks FD to forward some eczema mixture to Southampton for him

and to hunt out notes on earthworm activity at Beaulieu Abbey.

Forwards an unspecified work for FD to read.

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.]

Has had conflicting information on the movement of radicles; wants FD to experiment with them.

Sends letter and seeds from [F. J. Cohn].

Is working too hard.

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.

Will dispatch the best twisted stems he can find.

Considers the role of the pulvinus in leaf movement.

Suggests FD call on Carl Semper.

Inquires about Porlieria: Do the leaves shut to check evaporation? Does it appear silver under water?

Explains how he thinks the pulvinus acts; wishes FD would investigate the point.

Has a magnificent bush of Porlieria. There is no vestige of bloom; CD will test for sleep movements. Reports successful experiments on temperature-induced sensitivity of radicles.

Describes sleep movements in Porlieria and his experiments on movements of radicles.

Thalia flowers have interesting mechanism to ensure cross-fertilisation.

Asks for list of families of sleeping plants. Believes sleep is merely modified circumnutation at a particular time of day.

Porlieria has had no water for some time but shows no sign of flagging.

Describes the response of Thalia flowers to touch.

A report has arrived for FD which CD will forward.
