Will send a parcel once he receives instructions from Smith. Encloses '[Hypnum] proliferum' in fructification. Offers to send the 'verticillatum' of [John] Lightfoot; believes his attribution is wrong as it totally differs from those of Linnaeus and [William] Hudson. Similarly, Dr [John] Walker [(1731-1803) professor of natural history] showed that Lightfoot's 'Salix arenaria' is Linnaeus' 'Salix fusca', from specimens of [Daniel] Solander's. Offers to send Smith '[Ptilium] crista-castrensis'. Has found '[Sphagnum] palustre' and a 'Boletus' with a "delightful smell" he believes to be the 'suaveolens' of Linnaeus ['Trametes suaveolens'], Lightfoot describes one under the same name but with no odour. The society [Natural History Society, Edinburgh] "rather low" but has received a great addition in Mr Alexander. Hopes to submit a paper soon.
