Congratulates Smith on arrival of the Linnaean collections; considering visiting London to see them. Understands that the Linnaean mosses have thrown the British mosses into "entire confusion", and expects the same for the grasses, Umbelliferous, and Syngensious plants, and 'Salix'.
Received letter from [James] Dickson on 'Lycoperdon coliforme', which he is including in ["Fasciculus plantarum cryptogamicarum Britanniae"]; asks if Smith has seen [James] Sowerby's drawing of the specimen he sent. Asks how numerous 'Fucus' are in comparison to number in "Systema vegetibilium", and whether it is worth buying the new edition. If Smith disposes of any book duplicates requests [Peter] Artedi.
