Thanks for Smith's letter of 7 September [1789] and parcel of books; unfortunately several were damaged in sinking of boat. Smith's "Plantarum Icones" confirms that Smith has become Linnaeus' successor and scientific heir. Sent Smith complete set of Thunberg's "Dissertations"; will endeavour to find volume 4 of "Transactions of Royal Academy of Uppsala" and [Olof] Swartz' "Prodromus West Indies". Introduces [Adam] Afzelius, who should be in London by now

Notes on plants found on his summer tour of Cornwall: encloses seeds of 'Ligustrum cornubiensis', also has specimen of plant if desired; 'Genista pilosa', previously only known near Bury, growing amongst 'Erica vulgaris' on the soap rock near Lizard Point; 'Erica multiflora' on Goonhilly Downs near Helstone, universally with white flowers; offers specimens of soap rock.

Looks forward to personally paying his respects to Smith: his late brother [Sir John Cullum, 6th baronet (1733-1785)] often spoke of him and Lady Cullum says she is an old acquaintance.
