Working with London College of Physicians revising their Pharmacopoeia, queries botanical names with Smith: discusses different specimens of 'Melaleuca leucadendra' sent by Christopher Smith [(d 1807) East India Company botanist], from one of which cajeput oil is obtained; whether officinal juice is obtained from 'Aconitum napellus' or 'Aconitum neomontanum' of [Carl Ludwig] Willdenow; whether Smith has given a trivial name to the 'Alpinia' which yields cardamom; unsure whether the fruit of 'Laurus nobilis' is a bacca or drupa; and terminology for describing hops. Smith has annotated brief responses to each query.

Has named 'Malaleuca cajuputi'. Lack of papers at Linnean Society for reading at meetings. Smith's paper on the vitellus of seeds well regarded. Reading Smith's latest publication ["Introduction to Botany"], asks when an English "Lachesis Lapponica" is to be published.
