Writes about [H. R. Hope-]Pinker, who tried to approach CD via the Royal Institution in order to sculpt a bust of him. WS advises against agreeing to sit for him.

Refers to Charles Lagrange, who is working on the same subject as GHD, but in a fundamentally different way.

Rejoices that "Lagrange’s case does not seem very bad".

CD is working hard at dissecting Thalia. Has recovered some handiness with microscope.

Chlorophyll development in oat seedling.

Lists the sleeping plants he has seen.

Julius Sachs thinks Hugo de Vries has not cleared up everything [about climbing plants]. But Sachs has not worked on the mechanical problem.

Sends drawings of specimens [of Thalia] CD requested.

Thanks GHD for his drawings [of Thalia]. Some parts need attention.

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.

Writes to say that the point on which he thought GHD’s drawings were mistaken proves to be an error in his own observation.

Enjoyed OCM’s visit.

Sends photographs.

Movement and sensitivity of flower parts; relationship to cross-fertilisation.

Thinks it would be a good idea to give the typing machine to Karl Semper.

A report has arrived for FD which CD will forward.

Has found examples of small female flowers in Stachys germanica and Ranunculus bulbosus.

Discusses "highly expressive" speech of young children.

Sends specimens.

Sensitive plants.

Asks TW not to send more information as CD does not expect a new edition of Forms of flowers.

TW’s Stachys case is what he calls gynodioeciousness.

More sleepers from green-house.

Julius Sachs’s view of climbing plants: he distinguishes between nutation to find a support and growth after support is found.

Explains difficulties in supplying wings of geese. Describes injury of old gander that sired the abnormal geese.

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.

EFL’s account of what CD has done in natural history is full and accurate and could not have been done better. He has added the titles of his later books and the name of his maternal grandfather [Josiah Wedgwood] of whom he is proud.
