Sent copies of his "glossary"' ["Language of Botany"] to Smith and Linnean Society, includes: from "Hortus Kewensis" 'Achillea squarrosa', and from [Carlo] Allioni 'Achillea herba-rota', 'Achillea ligustica', and 'Achillea tanacetifolia'. Asks if Smith knows "'Achillea lutea' Krocker siles n. 1443". Difficulties with 'Achras' species in "Hort. Malab. vol 3 tab 29, 30, 31" [Rheede van Draakenstein's "Hortus Indicus Malabaricus"?] and between 'Achras' and [Olof] Swartz' 'Bumelia'. Asks what 'Achras balata' of Gmelin "Syst. 574.5" is. Preparing 'Aconitum' for press, asks for any of Smith's observations especially 'Aconitum lycotonum'.

Acknowledges Smith's thanks for dedication [of "The language of botany"]. Asks Smith to correct any errors in the glossary in advance of a second edition. Discusses botanical terminology and the trend of words changing their meaning.

Thanks for Smith's memoir on Ferns [published by Turin Academy]. Mortified by Dr [Robert John] Thornton's [(c 1768-1837), physician and writer on botany] rejection by Linnean Society; intends to propose him again, and if unsuccessful again will propose a change to the rules to reflect those of Royal Society. Concerned by "strong tendency" in Soho Square [home of Sir Joseph Banks] "to throw ridicule upon all persons and proceedings, except a certain set".

Believes that 'Myosotis scorpioides', 'Myosotis palustris', and 'Myosotis arvensis' are distinct species rather than varieties, his observations.
