Asks after Smith's "botanical institution" [Linnean Society]; understands they met at Smith's house and that Smith's introductory discourse was well received. Still waiting on Smith's 'Lycoperdon' notes so he can write paper on the genus; justifies his decision to focus on only British species. Sends parcel of a few marine plants for [Samuel] Goodenough, asks for his and Smith's opinion. [John] Pitchford has the true 'Fucus pinnatus' of [William] Hudson but convinced it is 'cartilagineus' of Hudson in fructification. Sends Goodenough specimens of common brown 'Fucus' of Yarmouth beach; observations on its "newness", specimen enclosed for Smith [envelope extant but specimen missing, labelled 'Fucus subsuscus', located 18.74].

Hoping to send some dubious plants for identification. Dedicating himself to botany and the 'Cryptogamia' class, will send a list of desiderata to Smith. Requests any species of 'Hypnum'. Offers to send following plants found around Paris: 'Lobelia urens', 'Sison verticillatum', 'Phalaris oryzoides', 'Spergula sagimoides', 'Sium repens-jacquini', 'Buxbaumia foliosa', 'Jungermania multifida', and several lichens, 'Bryums', and 'Jungermanias'.

Advises Smith to write to Noailles. Is working on Mammals and collecting insects. A recipe for preparing potato-pulp.

Introduces Davall; news.
