Thanks for drawings and "curious residium of burnt banknotes". Thinks it would be more valuable to keep the copyright of "English botany" as a perpetual source of income rather than selling it. Returning drawings for "English botany" no.244 and "Flora Graeca", finishing the third fasciculus. Has named and returns Sowerby's Labrador plants, except 'Swertia rotata' and true Linnaean 'Campanula uniflora', and his Irish 'Agrostis'. Requests return of German book on fungi. Sends specimens of 'Carex salina' and 'C. ustulata', with another 'Eriophorum' from "indefatigable" George Don.

[Draft of Sowerby's reply, in pencil:] Sends plants and drawings.

Sends new British plants for determination. Has heard through [Joseph] Sparshall that at least three people have died from eating poisonous fungi; frustrated that there is not "more Philanthropy shown on this head", suggests text for a handbill outlining dangers of 'Agaricus virosus'.
