in the base circuit of the Great House supplies
a simple masonic unit of cosmic length, a
standard of universal measurement.
Were this ratio an isolated instance, some
question might not unnaturally arise as to the
accidental nature of the connection ; but the
intention of the architect is strongly confirmed
by the kindred discovery due to Mr. Flinders
Petrie. That acute observer has pointed out
that the length of the raised pavement was a
simple measure (one-twentieth) of a geogra-
phical mile. And since a geographical mile is
a measure of the earth's circumference at the
Equator, a knowledge of it implies a knowledge
of the measurement of the polar radius.
Striking however as is the ratio which this
stone bears to the cosmic standard, its relation
to the Pyramidal Edge, of which it forms a
part, is no less prolific of universal results.
For, taking as the length of that base-line,*
* These results are as follows, expressed in our
