that map now before me, and this diſtance meaſures upon it 990 Olympic ſtadia, or 123 Greek miles and ¼. If we add to this ⅛, or 15 miles and ½, for the winding of the road, it will make up 139 miles and ¼, equal to 1114 ſtadia of 600 to a degree. Say then,^[1]1114:600::1485:700.8, or almoſt 800 to a degree.,

Let us now ſee what the number of ſtadia to a degree would be by Mr. Rennel's own numbers: ^[2] 118. x 8. = 944:600::1485:943.850, both calculations very different from that of Mr. Rennel.

But the road which we may preſume was uſually travelled is as follows:

From Piſa to Corinth	570	$\scriptstyle {\left.{\begin{matrix}\ \\\\\ \ \end{matrix}}\right\}\,}$	Olympic ſtadia according to D'Anville's map.
From Corinth to Megara	260
From Megara to Athens	220
Direct diſtance from Piſa to Athens	1049

Add⅛%, or 131 ſtadia, for; winding of the road, and the numbers will he 1180 ſtadia. Say then 1180:600::1485:755.08, a number not very different from the one aſſigned by Mr. Rennel, but not deducible from thoſe calculations which he has, ſpecified.

1. 600 Olympic ſtadia are reckoned equal to a degree, on Mr. D'Anville's map of Greece.
2. This is the number aſſigned by Mr. Rennel, with the addition of, ⅛ for winding of the road.
