of Edinburgh, Session 1870 - 71 . 
But on entering the Antechamber, we find this particular mea¬ 
sure or sacie ^-_ cu (which we have termed the Pyramid inch. 
to avoid expressing that particular measure of length by the 
algebraical x) not only typified, but expressed, and most notably 
in the granite leaf, whose precise functions have never yet been 
explained. 
For there—on a stone immediately in front of an unmistakable 
symbol of division into five—we find a raised boss, with a single 
straight edge exactly i of a Pyramid or sacred cubit in length, 
and consequently representing 5 of these inches. 
The thickness of this boss along the whole line of 5 inches is 
exactly J of that line, of the same cubit, or precisely the inch 
we are in search of. 
Further, the centre of this boss is exactly one inch from the 
middle of the Antechamber, its distance from either side being 
19*5 and 2P5 inches from the west and east walls respectively, 
and, consequently, it is one inch to the west of centre (just as the 
niche in the Queen’s Chamber, marking the whole 25 inch cubit 
by the breadth of its flat top, is also 25 inches removed from the 
central vertical line of the wall in which it is formed). 
It may be argued that all these expressions of an inch in the 
Antechamber depend upon the shape and position of a stone that 
was not necessarily placed there by the architect of the Pyramid. 
Let us, therefore, seek some connection with the grander fea¬ 
tures of the building, both for the stone itself and the particular 
measure of length, of which we are thus far led to consider it the 
standard. 
The following calculation shows that a line drawn from the 
angle of the great step at an angle of 26° 18', or parallel to the 
true axis of the Grand Gallery, passes about 1T3 inch below the 
centre of the bottom of the upper stone forming the granite leaf, 
or the one that bears the boss.
