Hence L(3-5785 , °32) = +-01461. 
Calculating in like manner for z= °325 and z= °33, we get the following values :— 
z I'(é <2) Diff.

Interpolating, we find ,z, = "3258; and therefore ,w,=°3484. It follows that 
10 = 3484 x 145°5 x 480,100 sq. ft. 
= 50°7 x 480,100 sq. ft. 
and 1, = 25°24 x 692-9 ft.
