352 A NOTE ON NOMENCLATUEE. By B. Daydon Jackson, Sec.L.S. In the haste to discover startling novelties in nomenclature, ifc is but natural that many mistakes should be made; the following in- stance is worthy of attention as denoting a tendency to overlook facts, and to mislead others who have not access to the authors quoted. Professor 0. S. Sargent, in his Silva of North America, ix. 27, employs Sweet's name Fagus americcma for a tree which has hitherto been known as F. ferruginea Ait. ; he cites as his authority Miinchhausen, Der Hausvater, v. 162 (1770). This work seems to be scarce ; I did not know of the existence of a copy in London until the printing of the Index Keivensis was proceeding, and then I found an imperfect copy in the library of the Linnean Society, which had been in the possession of Linnaeus, but had not been catalogued, and so escaped attention. I will extract the portions which relate to the tree in question, so as to make clear the actual position of facts. The title of the same memoir varies, as shown by the use of parentheses in the following : — (Ausfiihrliches) Verzeichniss aller Baiime und Stauden welche in Deutschland (in freyer Luft) fortkommen (oder als solche angesehen werden konnen). — Bd. v.
