- Having ascended along this channel, to the dis-

a horizontal duct, leading to a chamber with an 
angular roof, in the interior of the pyramid. In 
this passage we found, upon our right hand, the

in sounding it with a line, found the plummet

to ascertain the cause of failure in Greavess 
observation, and in those of almost all others 
who have attempted to measure the depth of 
this well. The mouth of it is barely large 
enough to admit any one into it; but, as it is 
possible to descend, it is to be regretted that 
the French, during all their researches here, did 
not adopt some plan for the effectual examina-

upon the nature of the pyramid, and the founda-

more time than travellers usually can spare,
