The Ark, or Laver by theory, and the Pyramid Coffer in prac- 
tice, contain 71321-2.5 B. I. = 71,250 P. I., the quarter of which, 
or 17812 , 5 Pyramid inches (the volume of this particular stone), 
is the Chomer or Homer of sacred standard. 
The remarkable result thus obtained induces a further examina- 
tion of the position of this stone. 
We remark that the base of this stone (lower stone) is in the 
same horizontal plane as three other well defined lines of the ante- 
chamber — viz., the division between the courses of the wainscot 
on the east wall' and the tops of the doors in the north and south 
walls. 
It is to be noticed that the refined workmanship of the granite 
wainscoting has been most fully developed to the south of the 
leaf. 
We will thus examine that portion first. The granite leaf itself 
and the granite walls mark off above the horizontal plane a cer- 
tain space. 
The dimensions of this part of the plane are — 
In length varying from (1.) 79-0 B.I. to 79T B.I. 
In breadth (2.) 4L2 to 4L45 B.I. 
While at the height of (3.) 27‘5 to 28 B.I. there 
runs across it the joint line of the leaf.
