Notes that although [Emanuel Mendez] da Costa's [(1717-1791), naturalist] manuscripts are chiefly concerned with mineralogy there are several on botany from [George] Edwards [(1694-1773)], [Georg Dionysius] Ehret [(1708-1770)], Knolles, [John] Martyn [(1699-1768)], [Philip] Miller, [Richard] Pulteney, and some others, and are available for Smith's use [for "A selection of the correspondence of Linnaeus" (1821)].
