In view of these discrepancies, shall we demand superhuman 
accuracy on the part of the pyramid builders? 
otwithstanding the remarkable proportions, and evident 
geometrical relations, from a rectangle of the height of the 
niche, yet, in practice, the builders appear to have made the 
walls of the north and south sides of the chamber almost 25 
inches lower than the niche. Was this careless workmanship, 
or was it designed? Let us see. We adopt 182°62 in. as the 
true height of the north and south walls, which is very near 
Prof. Smyth’s mean— 
182-62 in. x 100+814159=5818 in.= height of the pyramid, 
and calling the 182°62 so many cubits— 
18262 in. x 25=4565°5 in.= half base length of the pyramid :

Moreover, 182-62 x 2 = 365-24 = days ina year. If we take 
now 5818 in. and 9131 in., representing height and base of the 
pyramid, we get the following proportions :

The following are the results of the very accurate measure

The last number is, almost, the right sine of 90°, or wy the

We have thus the z ratio in the coffer, and exactly, if we me
