Researches on "Umbelliferae".

Has not heard from Smith for two years; uncertain if the Linnean Society has received his papers on genus 'Bertolonia', genus 'Callitriche', and descriptions of two new genera of 'Crustacea' and new species of Atlantic fish. Enquires after the bill he sent Smith with which to purchase and send him new natural history books. He has also sent the first volume of a scientific journal he has been publishing since the start of the year as well, but hearing no answer supposes it not acceptable. Encloses several pamphlets. Regrets that their correspondence is not more active. Wishes to know if "Flora Britannica" vol 4 and "Prodromus florae graecae" vol 2 are published.

Congratulates Smith on his knighthood. Suffering from angina pectoris, believes that it is not always fatal and refers to two cases mentioned by Parry in which one patient died in a fall and the other took arsenic by mistake. Asks after his paper on ivy.

Thanks for copy of Smith's "Introduction to Botany". Reports from his excursion into Yorkshire: wishes Smith had been with him at the "dropping well" at Knaresborough, there were jungermanniae, lichens, and mosses; found 'Inula helerium' and 'Sedum telefitium' in a hedge bank, 'Atropa belladonna' in churchyard near Ferrybridge, Yorkshire, and in hedges near the town, and 'Colchium autumnale' in meadows about Knaresborough. Recounts anecdote in Dr [Thomas] Zouch's [(1737-1815)], prebendary of Durham and FLS, unpublished "Memoir of the life of Dr John Sudbury", dean of Durham in 1661, about the detainment of the cathedral library's copy of [John] Gerard's "Herbal" by Colonel Robert Lilburn; thinks it curious in showing the estimation in which the book was held. Invites the Smiths to visit for the Bury Fair.
