Rh Arrian reckons the ame ditance to be 8505 tadia, or 1063 Greek miles, which divided by 8.5 gives 125 Greek miles, or 1000 tadia, for each day's ail of twenty-four hours, which agrees exactly with Ptolemy. The real ditance however appears to be about 13° of longitude, which in latitude 41° amounts to 682 Englih miles, which divided by 8.5 gives 80 Englih miles, or 87 Greek miles, equal to 696 tadia, for a day and night's ail.

Herodotus again ays, that the ditance from Sindica to Themicyra is 3300 tadia, and that this was three days and three nights ail. This allows 1100 tadia for every twenty-four hours fail, which is above the computation of Ptolemy. According to Mr. D'Anville, the ditance is about 2640 tadia, or more than 118110 [sic] Greek miles, in twenty-four hours.

I have thus examined the intances which Mr. Rennel thinks the fairet and mot to the purpoe; and I ubmit to the reader, whether I have not hewn, that the ditance, which he has acribed to the hips of antiquity as a day's ail, has not been by him underrated; and that 1000 tadia, which is the pace aigned by Ptolemy, is not very near the truth, on a medium computation.
