74 Mr Oxley, Magnetic Susceptibility with Temperature. 
The same remark applies to the representation of the results 
of Jaeger and Meyer*, although the curvature in their diagrams 
appears smaller.

In the following tables the first column represents the con- 
centration of the solutions, used by Jaeger and Meyer; the 
concentrations are expressed in gramme molecules per litre. The 
second column gives the absolute temperature. In the third and 
fourth columns the values of the constants A and B are given for 
each concentration as worked out from the experimental values of 
iven in column 5. Columns 6 and 7 show the agreement 
between the calculated and experimental values. For the calcu- 
lations in column 6 the relation

is taken, for those in column 7 the empirical relation used by 
Townsend and Jaeger and Meyer is taken (y = % (1 —e. #)). 
An examination of the numbers given in columns 4, 5, 6 and 7 
brings a considerable amount of information to light. It will be
