Cicero, repeating his new term quality, adds with great philosophical pleasantry, "Faciamus tractando usitatius hoc verbum, et tritius." And it may be said of the terms of natural history, that our elegant classical scholars will find their asperities wear off very soon, if, by adding to their former acquisitions a knowledge of this new philosophy, they make themselves practically versed in the use of them. There may remain some precisely descriptive, which may be yet added; some reformation may be wanted in those which may have been hastily adopted; and from them we may expect it.
