Thanks for Smith's hospitality in London. Details of his return journey via Huntingdonshire, including Ripton, Huntingdon, and Bury, where he dined with Sir Thomas Cullum and saw 'Holosteum umbellatum' adorning several thatched houses and 'Vicia lathyroides' near the town. At Cambridge saw 'Arabis turrita' on walls of St John's College. Will shortly be at Yarmouth, [Norfolk], from whence he will send [James] Sowerby 'Cinceraria palustris' and 'Convolvulus soldanella'. At Cambridge found [Richard] Relhan "quite crazy"about the "conjuror of Chalgravis" fern, inserted in appendix to "Flora Cantabrigiensis" under name of 'Acidium from Maller's "Systema"; observations including discussion of letter by Sir Joseph Banks on subject.
