Note 209 — BOOK XVIII. THE NATURAL HISTORY OF GRAIN.
John Bostock translation
This would rather grate the grain than pound it, as Beckmann observes. See his Hist. Inv., vol. i. pp. 147 and 164, Bohn’s Ed., where the meaning of this passage has been commented upon. Gesner, also, in his Lexicon Rusticum, has endeavoured to explain it.
