Received Smith's letter of January 1818. Requests Smith's advice and determination on enclosed plants, since Smith is "unanimously considered the prince of botanists and the world's oracle on matters botanical"; has not added any cryptogamic plants, considering it impossible to add anything to Smith's already complete collection, but includes a catalogue of Germany's mosses.

Has sought Robert Brown's "Prodromus Florae Novae Hollandiae" in vain, and is told the author has suppressed it. Both he and Dr [Carl Bernhard von] Trinius [(1778-1844)], author of "Fundamenta Agrostopraphiae", think Smith's 'Alopecurus alpinus' is interesting; requests specimens.
