76 Mr Oxley, Magnetic Susceptibility with Temperature. 
of the susceptibility of water into account is 0:07 x 10-, and 
corresponds to a temperature of 50°C. On either side of 50°C. 
the correction falls off and is zero at 0°C. and 100°C. due to the 
fact that we have made the curve pass through the extreme — 
points. When the corrections are made there is a better agree- —
