3^ inches from tlie original floor, a passage, 3 feet 5j inches in
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

The third chamber is 27 feet 3h inches long from east to
west, and 13 feet 7'2 inches wide from north to south. The sides
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.
