briefly as possible, the result of our investigations in the

27’: this passage, at a distance of some 300 feet, enters into the 
subterranean chamber 11, which is an unfinished room, 
situated about 106 feet vertically below the base of the pyra- 
mid, and it is cut in the limestone rock upon which the 
pyramid is built. The entrance passage is rectangular, about 41 
inches in breadth and 47 inches in height, lined with polished 
limestone of a much finer quality than that constituting the 
mass of the pyramid; and the joints are exquisitely fine. 
About 30 feet within the passage, at 2, in fig. 2, there 1s om 
either side a thin, fine, exquisitely-ruled line, cut by a master 
hand, exactly vertical by severest tests. Whatever else these

At 8, the ascending passage commences, at an inclination

closed by a triangular stone, inserted in the roof of the descend- 
ing passage at 3, and effectually concealing it. This stone was 
accidentally dislodged, during the progress of the forced entrance 
made into the pyramid by the Khaliph Al Mamoon, some 
8000 years after the erection of the pyramid, and by 18 all
