Note 50 — BOOK III WHICH TREATS OF THE DIFFERENT FORMS OF WATER
John Clarke translation
The ordinary text, as Koeller saw, is evidently wrong. It runs: “For by a secret path the sea water enters the ground and becomes visible, and returns stealthily, and is filtered, etc.” No author can be supposed to have written such a sentence. The restoration must be conjectural. I have adopted what seems simplest and most in keeping with the context.
