 Cairo had come out to visit it. In the mean time examined the small 

 Pyramids and tombs to the south and east which are in a ruined state. 

 Having measured off a base, took the height of the Pyramid with the 

 Theodolite, which agreed with a former one. Thence went down to 

 the plain on the north side, and having taken a base, found by means 

 of a Theodolite, that the Pyramid stands on an elevation 163 feet 

 above the river. 



* If we examine the measures given by the French, we shall find that the base of each 

 of the three Pyramids of Cheops, Cephren, and Mycerinus is to their perpendicular 

 height, nearly in the ratio of 8 : 5.; — Cheops is 448 feet H.; 728 L. of B. ; — Ce» 

 phren is 398 H. ; 655 L. of B. ; Mycerinus, 1 62 H, ; 280 L. of B«
