width, runs southward, for 23 feet 11 inches, to a third chamber,
the floor of which had been taken up to the depth of 14 feet.
The floor of the above-mentioned passage (which was originally
3 feet 5h inches high) had also been taken up, in order, probably,
to facilitate the removal of the large blocks from the inner

are perpendicular for 12 feet 1 inch, after which fourteen courses
project inwards, as in the other apartment; and the total height
from the original floor to the ceiling is 48 feet 1 inch.
