[4] In order to show the relations more clearly, the foreign measures most familiar to the Greeks are included in this Table.

[5] This is, of course, not the true number of English statute miles contained in a degree of a great circle of the earth, but the number computed from the data exhibited in the Table, some of which are only approximate; namely, 1 Degree = 75 Roman miles = 600 Greek Stadia, and 1 Greek foot = 12·135 inches. The true value of a degree in English miles is 691/51 = 69·0196, and the difference is only about 7-100ths of a mile.
