[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 numbercomputedfrom 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.
