In ſailing from Athenæ; we paſſed by Prytanis, a palace of Anchialus, which is diſtant from Athenæ forty ſtadia.
The river Pyxites is diſtant from Prytanis ninety ſtadia.
The diſtance from Pyxites to Archabis is alſo ninety ſtadia.
From Archabis to Apſarus ſixty ſtadia.
When we ſet ſail from Apſarus, we paſſed by the river Acampſis in the night, at the diſtance of fifteen ſtadia from Apſarus. The river Bathys is ſeventy-five ſtadia diſtant from the Acampſis.

From the Acinaſis to the Iſis ninety ſtadia. The Acampſis and the Iſis are both of them navigable rivers, from whoſe mouths iſſue ſtrong morning breezes.

It muſt however be obſerved, that the Pontic ſea is much leſs ſalt than the ſea without the Helleſpont, on account of the rivers which diſcharge themſelves into the former, the num-
