Calcaire hépathique. The stone used for the casing of the exterior of the Great Pyramid, and for the lining of the chambers and passages, was obtained from the Gebel Mokattam, on the Arabian side of the valley of the Nile. It appears to be similar to that named above, as it is described as being "a compact limestone," called by geologists "swine stone," or "stink-stone," from emitting, when struck, a fetid odour.
