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 Recounts anecdote in Dr [Thomas] Zouch's [(1737-1815)], prebendary of Durham and FLS, unpublished "Memoir of the life of Dr John Sudbury", dean of Durham in 1661, about the detainment of the cathedral library's copy of [John] Gerard's "Herbal" by Colonel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.

Postscript by Lady Cullum repeating Cullum's invitation.

Invites Smith and his wife to stay next week whilst [Aylmer Bourke] Lambert and Mrs Lochee are also visiting.

Violent headache compelled [Aylmer Bourke] Lambert to cancel his visit to Bury at the last moment. Approves of the advice given to Smith regarding Cambridge botany professorship and garden. Grieved by Smith's account of Dr [Martin] Davy's mortal illness and recalls others who have died or are dying from cancers of the mouth.

Reports on letters received from Mrs [Catherine] Lambert concerning [Aylmer Bourke] Lambert's ill health, including violent headaches and insomnia. Cornwallis Hewett to succeed as Downing Professor of Medicine following death of Professor [Busick] Harwood [(1750-1814), anatomist], although uncertain who will succeed to astronomical professorship, believes Hewett's father exhibited his collection of gold, topazes and amethysts to Smith at Cullum's lodgings in King Street, Covent Garden, [London]. Invites [William] Roscoe to call on him should he return from his Norfolk tour via Bury.

Mrs [Catherine] Lambert reports that [Aylmer Bourke] Lambert continues to have restless nights. Interested to see Smith's catalogue of Holkham manuscripts [home of Thomas William Coke], hopes Lady Cullum will be able to see the Raphael Delph at Narford [Hall, Norfolk, home of Andrew Fountaine].

Attended Royal Society anniversary and dinner with Sir Joseph Banks, Bishop of Carlisle [Samuel Goodenough], Mr Lysons , Mr Marsden, [Edward] Rudge, and Mr Raper. Attended Linnean Society meeting; Lambert was in the chair and [William George] Maton also attended but [Alexander] Macleay still recovering from his "violent peripneumony". Concerned by [Thomas] Marsham's removal from Baker Street to Winchmore Hill. Convinced [William] Webb in Cambridge to put himself forward for Linnean Society; [Arthur] Biggs' [(1765-1848), curator of the [Cambridge] Physic Garden, nomination certificate for Associate put up. Asks if Smith has seen [William Elford] Leach's "[Zoological] miscellany"; does not approve of the "frequent new generic names".

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.
