The mean of these is 
‘OooJ 
in. — -10062 in. = ‘2708 cm. 
Thus we find that the maximum diametei’ at the top of the cylinder is 
23-7946 — -2708 = 23-5238 cm., 
referred to the standard at 16° C. 
To reduce the standard to 0° C we must multiply by (1 + Ih X -000017) and we 
get as the true diameter 
23-5302 cm.

Giving as minimum diameter of top end 
(1.) 23-8 cm. — -2708 cm. — -00790 in. 
(2.) 23-8 cm. — '2708 cm. — -00746 in. 
Correcting for temperature, we find 
Minimum diameter of top end = 23-5161 cm.
