Rh acred tream, is doubtful. From the Acinans to the Iis 90 tadia. From the Iis to the Mogrus 90 tadia. This river is noticed by Pliny under the name of Nogrus. From the Mogrus to the Phais 90 tadia. This river preerves in ome degree its ancient name, being till called the Faz, or Rion. Its mouth is placed by Ptolemy in 45° N. Lat. and 72° 30' E. Long. According to Arrowmith's Chart it lies in nearly 42° of N. L. and 59° 6′ 50″ E. Long. from the Canaries. The map of the country between the Capian and the Black ea makes it to be 42° 25′ N. L. and 59° 2′ E. from the Canaries. Ptolemy then makes it, according to the lat computation, no lets than 13° 28′ too far to the Eatward, which is nearly 685 Englih miles, a vat difference, which mut effectually confound all calculation.

The mouth of the Phais is, according to Ptolemy, $31⁄36$ of an hour to the Eat of Alexandria, which is equal to 35 minutes of time, or 8° 45′ of longitude, which in latitude 42° is equal to nearly 452 Englih miles. This calculation, although erroneous, is les o than the former.
