CD and son [Francis] working on spontaneous movements of plants and heliotropism.

Has given [Raphael Meldola] permission to read extracts of FM’s last letter [not found], on odours emitted by moths, before Entomological Society [Trans. R. Entomol. Soc. Lond. (1878): ii–iii].

Thanks FM for letter of 22 Feb [not found] on Lepidoptera. Will send it to Entomological Society to be read. FM’s earlier letters produced best discussions of the season.

Thanks for seeds of Viola.

He and Francis [Darwin] are at work on biology of seedling plants and wish to observe how the flowers penetrate the earth.

The Pontederia did not germinate, probably pressed too much [in post].

Has forwarded FM’s letter to Raphael Meldola.

Thanks for information on Mimosa.

Would like to know how Cassia behaves in the rain.

Thanks for seeds

and information about earthworms.

Is working hard at movement in plants.
