Rh graphical information, and perhaps with a view of constructing an Itinerary of this coat, similar to those of various other parts by Antoninus. The measurements of the distances in the first part appear to have been taken at ea; but how they were ascertained, it is not easy to ay. Several ships we know were employed, and perhaps the ditances may have been computed from a medium of the calculation of each. They are too near the truth to allow us to uppoe, that the time which elaped in the paage from one place to another was the only guide they had in ultimating the interval between them. They may poibly be reckoned according to the meaurements by land. The commencement of the voyage is dated from Trapezus, a Greek city, and a colony from Sinope, ituated on the Southern ide of the Euxine ea The dimenions of the Euxine ea have been variouly repreented. I here give the bet account of its length and breadth I am able to collect from modern writers and geographers.

Firt then of its length.

Its, greatet length, as meaured nearly on a parallel of Latitude from Eat to Wet, eems to be from the mouth of the Phasis to the correponding Latitude on the opposite ide.

According to Laurie's Chart, the mouth of the Phais lies in Long. 41° 33′ East and Varna on the oppoite ide lies in Long. 28° 13′ Eat. The difference of thee is 13° 2.5′, which in Latit. 42° 30′ amounts nearly to 687 Englih miles. Fadwn's Map of Turkey in Europe makes the mouth of the Phais to be in Longit. 41° 18′, and Varna to be in 23° 4′ The difference of thee is 13° 4′, or nearly 669 Englih miles and a half. D'Anville places the mouth of the Phais in Longitude from London 42° 31′ 10″, and the oppoite hore (in the ame Latitude) in 28° 46′ 10″, The difference of thee is 13° 45′, equal to 703.564 Englih miles, Arrowmith's Chart puts down the mouth of the Phais in Long. 41° 21′ 30″, and the oppoite shore on the parallel of 42° in nearly 28°. The difference of thee is 13° 21′ 30″, equal to 687 Englih miles and a half nearly.

According to Citizen Beau champ, the length of the Black ea is 214 nautical leagues, equal to 642′, equal to 740.44 Englih miles nearly: but I think this calculation over-rated. He computes from the mouth of the Phais to the meridian of Trebizond 32.6 leagues, equal to 97′.8, equal to 113 Englih miles nearly: but the Charts make the difference of Longitude between Trebizond and the Phais to be no more than 1° 40′, equal to 86 Englih miles nearly, which makes a difference of 27 Englih miles in that portion of the ditance. It mut however be conidered, that as Varna lies 1° 14′ to the North of the Phais, he etimates the ditance from S. E. to N. W. but this obliquity will only make the whole ditance to be 690 Englih miles, which is 50 Englih miles hort of what he pecifies. , nearly in the
