394 H. L. Smith—Queen’s Chamber in the Great Pyramid. 
Piazzi Smyth at 5818 pyramid inches, =5819 British inches; 
and the length of base as 9181-05 pyr. inches, = 9140 British 
inches, nearly. These measures we adopt. 
Supposing now the triangle XNS, fig. 2, to be so constructed 
that 20X :4NS::1°:3-14159, &e, i.e. the circle struck with 
this supposition, the angles XNS, and XSN, can be compuit 
and they are found to be 61° 51’ 14” 3. And again, peculiar 
to a triangle with the proportions we have supposed, are three 
other angles, viz: 
26° 18’ 10” * Upper culmination of pole star. 
ti 
3 it 
83 41 50 Lower culmination. 
And also, derived from above, 41° 59’ 48” ‘7, angle of arms. 
With these angles demanded, we enter the Queen’s Chamber; 
let us see what we shall find there. pie 
We remark that Prof. Piazzi Smyth had no conce tion 0 
‘ ° e made 
his measurements; and, as he had no theory with regard to It 
unbiassed ; at the same time, there are certain portions © but 
we could have wished he had more carefully measured ; th 
when he states that other portions have been measured W! 
care, we feel bound to adhere very closely to his ge ae

aving an idea from the roughness of the floor, evident
