Enjoyed his time in London with [Robert] Batty who now thinks of setting up as a surgeon and apothecary. Broussonet has been appointed professor of oeconomy at Paris and is working on a "Flora Monspeliaca". Returned [William] Withering's proofs, with comments.

His purchase of the Linnaean library and collections for 900 guineas; lists the contents, being everything owned by both Linnaeuses [Carl Linnaeus (1707-1778), and Carl Linnaeus the Younger (1741-1783)], excepting the fossils of the elder which are given to the University of Upsal. Describes his luck of being friends with the man who was employed to negotiate a sale to Sir Joseph Banks. Estimates its value and ability to return. Intends to return to Edinburgh next winter.

Congratulates Smith on acquisition of the Linnaean collections, "undoubtedly the most valuable that could come into the hands of any naturalist". Presumes Smith will part with some of the collection and retain the herbarium; comments on disposal of rare books, harnessing the value in the manuscripts, and selling off the shell, fish, and insect collections on account of their fragility. Discussed the purchase with Smith's father, who is happy with it and Smith's prudence that it will not interfere with his studies. Warns against Russian roubles.

Pleased Smith's purchase of the Linnaean collections will probably exceed his expectations and that he is keeping the greater part; understands that the Professor of Botany at Oxford [John Sibthorp] offered a large sum for the herbarium. Suggests Smith write a "Flora Britannica" by comparing Smith's specimens against Linnaeus'.

Recently moved house. Commissions Smith to purchase the Aberdeen merchant's fossils before leaving London, directions for sending.

Sends specimens of 'Lycoperdon coliforme', 'Pervia cyathoides', and 'Lycoperdon phalloides' for [John] Pitchford, 'Lobelia urens' for Dr [John] Hope, and 'Lichen vulpinus' and a grass; observations and habitats. Reminds Smith of various promises regarding acquisition of mineralogy specimens and books in London.

Thanks for catalogue of fossils and minerals [from the London "fossilist"]; queries and places orders for several items. Hopes the specimen of 'Lycoperdon coliforme' he sent was useful; will gather more information before Smith presents it to the "Edinburgh society". Fears a parcel of specimens he sent to Norwich is lost. Examined 'Liquidambar styraciflua' but found no gum. Details of Smith's payment for [Richard Relhan's] "Flora [Cantabrigiensis]".

Annotation at head of of recto of first folio on "mountain green" and "iron with arsenic" [presumably in reference to Woodward's mineralogy specimens]

Thanks for the "Monachologia", the truth in which must have "extremely enraged" the gentry concerned; reactions of [John] Pitchford, [James] Crowe, and [Robert] Stone [(c 1751-1829), botanist]. [James] Dickson's work on 'Cryptogams' progressing; Sir Joseph Banks is engraving the plates for him; 'Lycoperdon phalloides' is to be included; thinks 'Lycoperdon coliforme' should be; [William] Withering's reasons for not figuring it in his own cryptogamic plant catalogue. Withering thanks Smith for his paper, he knew of Smith from Dr Stokes. Severe frost, which has brought out a great variety of wild fowl, identified with [Thomas] Pennant. New fasciculus published by [Pierre Marie Auguste] Broussonet.

Sending Smith proofs of first sheet of [William] Withering's work, for Smith's comments; his own opinion; discusses pronunciation and accenting of trivial names; [John] Pitchford will be unimpressed that Withering has not inserted [John] Ray's synonyms. Thanks for 'Ulva umbilicalis'. Received a lichen from Devonshire, where many of the Scottish ones grow.
