superstitious Arabs to deface them. Thence went, and measured the 

 two oblong holes cut in the rock on the east of the Pyramid. Enter- 

 ed and took all the dimensions of the inside. In the afternoon went 

 in again, and descended into the pit. 



Oct. 21. — Visited and took the dimensions of the second and 

 third Pyramid *, and the two ruined buildings to the east of them, be- 

 sides thi'ee small Pyramids to the south of the third ; having measured 

 likewise the pyramid on a square rock. Struck down towards the 

 Sphinx, and arrived at the boat after sunset. 



Oct. 22. — Went with the Theodolite to take the height of the 

 large Pyramid ; but deferred it on seeing one of the great people of 

 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 ao;reed with a former one. Thenre 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 Myceriiius is to their perpendicular 

 height, nearly in the ratio of 8 : 5.; — Cheops is 4^18 feet H. ; 728 L. of B. ; — Ce- 

 phren is 398 H.; 655 L. of B. ; Mycerinus, 162 H. ; 280 L. of B.
