Rh The lat intance I hall produce from Arrian hews a nearer coincidence. From Ceraus to Trapezus is, according to Arrian, 745 tadia. It meaures on D'Anville's map 660; and, with the addition of ⅛, = 85 tadia, makes up 745, agreeing exactly with Arrian. Arrowmith's chart agrees nearly herewith. It meaures by that 649 tadia; and, with the addition of ⅛, equal to 81 tadia, makes up 730 tadia; not differing o much as two Greek miles from the calculation of Arrian.

There is in the 28th volume of the Mémoires de Littérature, page 362, a paper written by Mr. De la Nauze, on this ubject. He is of opinion that Herodotus, Xenophon, Ariitotle, and other writers of antiquity, employed a Radium of ten to a mile. He begins his proof of this with aying, that Herodotus acribes fifty fathoms, or, to the depth of the lake Moeris in Egypt, which is rendered by Pliny fifty paces; and as the former of thee meaures was to the latter in the proportion of 6 to 5, he inferred that the tadia of Herodotus were ten to a mile. But firt, the proportion of 6 to 5 is not correctly the ame with that of ten to eight. 0: 5:: 10: 8.333. Again, there is reaon to think that the paus, when applied to explain the ., means ix feet, and refers to the expanion of the arms, not of the legs. Piticus's Lexicon derives it "a pais vel expanis brachiis, et dicitur Græcis, quæ et menura ex pedum, quæ inter ambas manus, menurato imul pectore, continetur expanas."

Another intance adduced by Mr. La Nauze is taken from the uppoed ditance between Epheus and Sardis. But this has been o differently computed by geographers, modern as well as ancient, that it is difficult to draw any concluion. Ditance
