Lady Cullum losing her eyesight to cataracts but Sir William Adams [(1783-1827), oculist] will not operate till she is almost completely blind in both eyes, hopes it can be done by May as warmer summer months not suitable.

Attended Royal Society meeting and dinner; Sir Joseph Banks too ill to attend but [Davies] Gilbert, Mr Raper, Dr [John] Latham, and [Aylmer Bourke] Lambert did. Was not aware of Mrs [Catherine] Lambert's "deplorable state" until seeing the muffled rapper on Lambert's door; a letter from Sir George Staunton says she continues in the same way, he has lately bought an estate at Leigh in Hampshire. Received from Copenhagen the continuation of "Flora Danica", observes that "Flora Britannica" and "English Botany" are frequently quoted, along with [Thomas] Velley and late [John] Stackhouse. Congratulates Smith on his appointment to botanical professorship at the Royal Institution. Flattered by Smith's article on 'Cullumia' in [Abraham] Rees' "Cyclopedia" which has been copied by Dr [John] Sims in the "Botanical Magazine". Encloses note for Smith's neighbour, Stevenson [not extant].

Waiting for Lady Cullum to have her cataract operation before coming to London; hopes to attend meetings of Antiquarian and Horticultural Societies and Linnean Society anniversary meeting, though Smith will have to announce deaths of [John] Stackhouse and [Thomas] Woodward. The "celebrated" Arthur Young [(1741-1820)] of the Board of Agriculture died recently at Bradfield, near Bury. Introduces Mr Longstaff, bearer of this letter and an astronomcial lecturer. Hopes to attend some of Smith's Royal Institution lectures on "the affinities of plants" in May. Has grown plants of either Smith's 'Dianthus virgineus' or 'Dianthus alpinus' from his "Tour of the Continent" from seeds collected on ruins of Catullus' villa on Lake Garda. 'Tulipa sylvestris', 'Rheum undulatum', and 'Scrophularia vernalis' coming into flower soon.

Lady Cullum's cataract operation a success: performed in under five minutes with no pain and before the intense heat of June which would have complicated her recovery. Operation took place same day as Sir Joseph Banks' death, 19 June. Observations on possible 'Dianthus virgineus' grown from seed collected on Lake Garda and mentioned in last letter, it is figured in "Botanical Magazine" tab.1740. Thinks [Nathaniel Shirley] Hodson's [(fl 1800s-1830s)] botanic garden at Bury "a romantic scheme" but has subscribed two guineas and though Hodson is unqualified and "quite an amateur of flowers" he has occassionally procured curious and scarce plants.

Prior to operation Lady Cullum's eyes were treated with drops of infusion of leaves of 'Atropa belladonna', some oculists also use 'Datura stramonium' and 'Hyoscyamus'; believes [John] Ray confounded the effects of 'belladonna' and 'datura' in "Syn[opsis methodica stirpium Britannicarum] p.266", though it now turns out both dilate the pupils [Smith has annotated "Ray caused this confusion - compare ed. 2 & 3"]. Did not see [Aylmer Bourke] Lambert before he left London, little hope of Mrs [Catherine] Lambert's recovery. Invites the Smiths to visit Bury in October.

Mary Cullum adds postscript, in her own hand, sending her love to the Smiths.
