Mr. S. R. Milner on the Heats of 



It will be seen that the latent heats calculated from 

 Clausius's equation are slightly different from those given 

 by Griffiths and Marshall, so that while b diminishes con- 

 siderably at high temperatures, its substitution in van der 

 Waals's equation gives a very constant value of a through a 

 wide range of temperature. The calculation of b becomes 

 very uncertain at low and at high temperatures, so that no 

 reliance can be placed on the result at 202 o, 3 ; b would have 

 to be still smaller than it is to bring a down to the normal 

 value.
