be considered on the opposite slope, we have f inch per degree, and a strong warrant
for considering it both ways will be found in the Queen's Chamber. This angle and its
equivalerne, as well as the angles of the air channels, are only mentioned as conjec-
tures, as the data at present are insufficient to give the ideas much weight.
This, however, is not the case in the angles of the passages, of which we know
enough to test any supposed reference properly, and which are so nearly the same
that they may be considered as one, the variations being perhaps to accommodate
difference of level, or possibly to include references which required slightly different
angles.

For considering the general angle perhaps the mean of the Entrance passage and
Grand Gallery would be the truest datum, as the First Ascending passage has been
stated by Prof. Smyth from its inferiority to give the impression of being merely
a necessary means of communication, and therefore not of symbolic importance
itself.
The angle to be considered then is (avoiding unnecessary fractions) 26° 23' ±4' sex-
agesimally, or 73°• 3 ±# 2 Pyramidally. This not being a round number or a simple
fraction (its nearest simple expression being -3- J the question is, if it resembles any
number elsewhere used. Now the number of cubits in the base (or earth revolutions
in the year) is 366*2563612 which divided by 5 is 73*25127224 (sexagesimally
26° 22' 13e//649) a very close approach to the mean value 73*3 ±'2, in fact varying
from this mean less than a quarter of the probable error.
The equivalent in measure of these degrees, is the next point to consider ; for this
there are many originally marked out portions of the passages, of which the vertical
heights may be fairly considered, and the number of cubits or inches per degree, on
those perpendiculars.
The first example we meet with is the Entrance passage, the vertical height of the
total shaft of which contains 1 cubit per degree(A). Then up the first ascending passage,
till we come to the level of the theoretical floor of the Queen's Chamber passage (at
the roof of said passage), we have for the vertical height of this portion, 10 inches per
degree(B). The next marked portion is the beginning of the sloped floor of Grand
Gallery, from the main cut off to the South wall; the vertical height of this portion is
