In Paris Broussonet took him to Académie des Sciences and established correspondence between him with [Jacques] Dorthes in Montpellier, [France]; no time for the Société d'Agriculture. Deep snow drifts on journey from Pontarlier, [France], to Orbe. Insulted by [Jean Louis Antoine] Reynier's [(1762-1824), botanist] criticism of his Latin. Found 'Carex tomentosa' for [Samuel] Goodenough. Ordered six copies of the new edition of Leers' ["Flora Herbornensis"] being published in Berlin. The lesser 'Caryophylla' in his herbarium could be worth Smith's attention. Believes they both hold 'Arenaria striata' and 'Arenaria liniflora'; the first is alpine and the second is Jurane and answers to plant at Kew. What he thought was a 'Colchium montanum' in his garden may be 'Bulbicodium', and if so an addition to the Swiss flora. Asks Smith's advice on 'Chenopodium' of Linnaeus and [Albrecht von] Haller with detailed reference to various publications. Has been sent Leers' 'Hypericum dubium' and a friend found Jacquin's '[Hypericum] barbatum'; offers to send these and 'Phaca australis' from Reynier's herbarium.
