Expansion of Brass. 
The mean rate of expansion of cast brass from 0° to 100°, usually assurnecfc 
0*0000187 of its length at 0° for 1°, is considerably larger than the rate at ordinary 
atmospheric temperatures, according to the observations of Mr, Sheepshanks , 
who found that at about 17 ° the coefficient of the linear expansion of cast brass 
=0*00001722.
