It hould be conidered, that this quantity was aigned to each mile, at the firt erection of mile-tones, when their computations might be les correct, and when, as Aulus Gellius tells us was done in later ages in ome places, they preerved the number of feet in a tadium, though they reckoned by a horter foot.

Mr. D'Anville has, I think, incautiouly blamed Cenforinus, for faying, that the Italic and the Olympic itadia were of different lengths, when he might mean only, that the Olympic and the were different, ince We can carcely uppoe ~a man of the learning of Cenforinus to be ignorant of the difference of length between the Greek and the Roman foot..

Let us now endeavour to acertain the length of the Greek foot, as on this the other calculation mut in a great meatfure depend. For this purpoe it will be neceary firt to conider the length of the Roman foot. Dr.
