#3 Number of pyramids in Egypt: the Principal Three

There are from 60 to 70 pyramids in Egypt, chiefly in the neighbourhood of Memphis. Some of them are nearly perfect, some more or less in ruins, but most of them still preserving their ancient shape, when seen from afar. Two of them greatly exceed all the others in their dimensions, and are appropriately designated as "the Great Pyramid" and "the Second Pyramid." A third in their immediate vicinity is of very inferior size, and scarcely deserves the pre-eminence which has been conceded to it by the designation of "the Third Pyramid."
