Note 9 — Chapter II
Reading edition
If we can depend on Mr. Perring’s determination, the Egyptian cubit used in fixing the dimensions of the Great Pyramid was more than half an inch shorter than the Babylonian or Halicarnassean cubit used for that purpose in the Mausoleum. As far as can be ascertained, the Egyptian equalled 1·713 foot English, while the other was 1·771; the difference being fifty-eight thousandths of a foot, or nearly two-thirds of an inch.
