Having had the honour to exhibit very lately a curious unpublished small brass coin, to your Lordship and the Society, which bore on the right side a female turreted head, and on the reverse a square inscription, as follows, ΑΤΟϒΣΙΕΩΝΤΩΝ ΠΡΟΣ ΤΟΝ ΚΑΠΡΟΝ, and within the square, an arrow and a palm-branch; I beg leave to make some further remarks upon this very rare and interesting coin, which I then, in my first dissertation, supposed to belong to a town of Atusa, situate on the Caper, that, in conjunction with the Lycus, runs into the Mæander, in Asia Minor; but, upon reconsidering the matter, I am convinced that the Caper, in Asia Minor, is not the river on which Atusa stood; but the Caper which, as well as the Lycus, runs into the Tigris. I in some measure prepared the way for this opinion, by observing in my late paper, that the arrow on this coin was a type of the Tigris, or Dejlet of the Persians, or ancient Hidekel of the Assyrians. I shall now state my reasons for believing that the Atusians were inhabitants of the banks of the Caper that runs into the Tigris, and not into the Mæander.
