Note (25) — BOOK IV.
James Greive translation
25. Ferula answered to narthex among the Greeks, and was a general name for several herbs of the same genus, from whence some of the fetid gums are obtained, as sagapenum, and galbanum.—The ancients made use of the stalks of these herbs, in the same manner as paste-boards are now used for fractures, as will be seen in the eighth book.
