Plans to write an account of his trip to Morocco and, with John Ball, the botanical geography, for Linnean Society.

Results mainly negative; the Atlas exhibits "the dying out of European flora".

Only two or three beetles above 8000ft.

Disappointed that Canary Island species are absent from Atlas mountains; but an ocean current along Moroccan coast should help migration of Spanish, Portuguese, and Moroccan seeds to Canaries and Madeira.

Describes Lyell’s poor physical condition. Asks CD for his observations of symptoms.

He did observe that Ophrys apifera fertilised itself as CD described and O. lutea as well.

Moroccans are too civilised, taciturn, and unfriendly to make anything of them for expressions of emotions.

Moraines and negative results on Atlas alpine flora are the only points of the journey worth much.

No summary available.

Has given CD’s name to a species of Abutilon found by Fritz Müller.

Pleased at Henrietta [Darwin]’s engagement.

Identifies Henslow’s mouse that used tail as prehensile climbing organ as Mus messorius.

Has not seen the Quarterly Review.

Inquires after Lyell’s health.
