To Mr. Rennel's aſſertion, that there is no teſtimony of the application of the Olympic itadium to itinerary purpoſes by Herodotus, it may be replied, that there is as much teſtimony as could be expected. It is deſcribed as a ſuperficial meaſure by that writer, and its parts or ſubdiviſions particulariſed, and this but a few lines after be had ſpecified the extent of the lake Mœris,From the dimenſions of the lake Mœris. which he eſtimates at 3600 ſtadia, or 450 miles, in circumference, a ſpace which Mr. Rennel will ſurely allow to be ſufficient to be accounted an itinerary computation. Now Herodotus never deſcribes any other ſtadium, or gives any reaſon to think, that the one uſed in computing the extent of the lake Mœris was of a different length from the one deſcribed juſt: after. It is worth remarking, that Herodotus, at the beginning of the ſame book, tells us, "that thoſe who have but a ſmall portion of land, meaſure it by the ὀργυιὰ, or fathom; thoſe who have more, meaſure it by the ſtadium; thoſe who have much, by the paraianga; and thoſe who poſſeſs countries of great extent, by the ſchoenus; the former of the two laſt-mentioned meaſures conſiſting of 30, and the latter of 60, ſtadia. Now the ὀργυιὰ is mentioned as the next diviſion to the ſtadium in both theſe places, and of courſe we have reaſon to think that the ſame ſtadium was meant in both.
From the diſtance between Piſa and Athens In order to prove that Herodotus meant to expreſs a Radium ſmaller than the Olympic, Mr. Rennel takes the diſtance between Piſa and Athens, which, he ſays, ought, if the numbers be not corrupted, to be accounted deciſive." This diſtance was, according to Herodotus, fifteen ſtadia ſhort of 1500, or 1485 ſtadia; and this, he ſays, agreed nearly with the one between Heliopolis in Egypt, and the ſea. "The direct diſtance," Mr. Rennel ſays, is, "in D'Anville's map of Greece, 105 Greek miles." I have
