Responds to Smith's letter of 24 September: condolences on death of Smith's brother; will enquire of [Jacob] Wyttenbach the particulars of the Berne fireworks display costing more than Haller's collections; comments on error by [Georg Franz] Hoffmann with 'Lichen omphalodes' in "Enumaratio" 4o p.76 and his "Plantae lichenosae" vol 1 p.40. Glad [Adam] Afzelius and François have returned, sorry their collections were attacked by insects so much and asks what liquor Smith uses to protect his specimens. Discusses his agreement with François [Borone] to be supplied with specimens as he is keen to increase his herbarium which is difficult to do in Switzerland; keen to start correspondence and exchange of specimens with [Thomas] Woodward. Will send Smith dried specimens of 'Melampyrum cristatum' this summer, in Switzerland it is a grove plant never seen in corn; he has given a foreign turn to 'Galium pusillum'.
