march as the Roman armies were in the middle of the fourth century.
Mr. Rennel again allows that Strabo reckoned eight ſtadia to a mile, and that ſeemingly on his own judgment; and afterwards ſays, that if the opinion of Polybius is to be followed, one-third of a ſtadium is to be added, as he has allotted 8½ ſtadia to a mile. But I have before produced a paſſage from the works of Polybius, now extant, in which he allows eight ſtadia only to a, mile; and it is probable that the paſſiage cited by Strabo might be only to accommodate the Greek to the Roman meaſure, if it be not, as I have before hinted, a miſtake of Strabo himſelf.
It is rather incorrect in Mr. Rennel to ſay that 8½ Olympic ſtadia, Of 600 feet each, were equal to 5000 feet. If he meaſures the Olympic ſtadium by Roman feet, and allows only 600 of theſe to a ſtadium, contrary to the account given by all the Roman writers, who aſſign 625 Roman feet to a ſtadium, his calculation will hold good; but it is more natural to ſuppoſe that a Greek meaſure ſhould be computed by Greek feet. If theſe were meant, eight Olympic ſtadia, without any addition, though containing only 4800 Greek feet, would be equal to 5000 Roman feet, as has been obſerved before.
Miſtake of Mr. Rennel.It is unfortunate that a perſon of Mr. Rennel's ſagacity and abilities ſhould fall into ſuch a miſtake, as to ſuppoſe, that a figure of eight could be ſubſtituted in place of a figure of in the MSS. of Strabo, when the uſe of the Arabic numerals was not introduced until a later date than that of any good MSS, of that writer, and when the number is not expreſſed by any numeral
