units are very numerous, and, unless referred
to cosmic principles, quite miscellaneous, hav-
ing no apparent co-ordination either among
themselves or with anything else. When
however taking as our unit the polar inch,*
we compare them with the measures of light,
as expressed in the shining circuits and radii
of the celestial periods—remembering always
that the radii and semi-radii of the cycles of
years are both consonant with the angular
construction of the Pyramid and are secretly
involved in the analogy of Illumination—we
find a most remarkable correspondence in
measure after measure, not absolute indeed,
but different only by decimals of an inch.
Take for example, the number of polar

Professor Smyth, and called by him the " Pyramid Inch j"
but he has so inextricably associated that name with views
directly opposed to Egyptological research, that I prefer
