Sending what he can of Dickson's desiderata, observations on numbered specimens, including: 'Lycoperdon forincatum', 'L. stellatum', new 'Byssus', a 'Boletus', an 'Agaricus', 'Clavaria ophioglossoides', 'Botelus luteus', 'Carex inflata', 'Saxifraga autumnalis', may send 'Polycarpon tetraphyllum'. Lately found new specimen he supposes 'Drosera anglica'. Will send 'Salsola fruticosa' and 'Erysimum cheisanthoides' by [James] Crowe.

Requests complete list of Dickson's desiderata. Appends his own list of desiderata [extant, 3pp], and list of plants for Dickson to acquire from Curtis. Also sending [John] Pitchford's 'Polycarpon tetraphyllum', possibly 'Drosera anglica'.

Thanks for plants, especially 'Lobelia urens' and 'Subularia aquatica'. He is going to Edinburgh in a month to study Physic, hopes there he will be of more botanical assistance to his friends. Doubts over 'Elymus arenarius', will look for 'Bryum rigidum', asks if 'Elatine alsinastrum' is a lost plant. Amazed to hear that an 'Arbutus andrachne' sold at Dr Fothergill's for 51 guineas.
