[Footnote 61: Abulfeda (Annal. Moslem. p. 210, 211, vers.
Reiske) describes this operation according to Ibn Challecan,
and the best historians. This degree most accurately
contains 200,000 royal or Hashemite cubits which Arabia had
derived from the sacred and legal practice both of Palestine
and Egypt. This ancient cubit is repeated 400 times in each
basis of the great pyramid, and seems to indicate the
primitive and universal measures of the East. See the
Metrologie of the laborions. M. Paucton, p. 101 - 195.]
