Note 479 — Book XIII.
John Beames translation
Fossatum. This word occurs in Pliny. It seems to have been chiefly used by the old Lawyers in two senses—1. as denoting a camp, or intrenchment—2. as meaning a ditch, dyke, or moat. But it was not always confined to these significations—as the reader will perceive on turning to the Ancient Glossaries, particularly to that very valuable one given to the world by Spelman.
