Note 571 — ANCIENT ROMAN MEDICINE-STAMPS.

See Ledwich’s Antiquities of Ireland, p. 45—Roman coins found at New Grange. A celebrated passage in Tacitus proves that, even as early as the first century of the Christian era, the Irish seaports were better known to the merchants of these times than those of Britain were—(“Melius aditus, portusque per commercia, et negotiatores cogniti”). See Agricolæ Vita.
