Note (28) — BOOK VII. (continued 2)

28. Come out prone, that is, with its end foremost, ut pronus exeat.) This Constantine changed in the margin into Ut ne pronus exeat, which Linden received into the text. Constantine explains prone by lying on its side, and says it is hardly possible to extract an oblong stone in that posture, supposing, no doubt, that it must necessarily lie across the orifice. See Morgagni, Ep. v. p. 128.
