Note 500 — Chapter I

Gosselin remarks that these 3700, or rather 3800 stadia, on proceeding from Marseilles, would reach the latitude of Paris, and that of the coasts in the neighbourhood of Tréguier. Eratosthenes and Hipparchus were out but 14′ and some seconds in their calculation of the latitude of Marseilles; but Strabo’s error touching the same amounted to 3° 43′ 28″ he consequently fixed the northern coasts of France at 45° 17′ 18″, which is about the latitude of the mouth of the Garonne.
