414 DETERMINATION OF THE FREEZING-POINT DEPRESSION 



The following table gives all the data together with the 

 values of k and I thus obtained. The values of the ionization 

 coefficients given were taken directly from the second of Dr. 

 MacGregor's papers referred to above. The letters i and e 

 which follow the coefficients indicate as to whether the values 

 were obtained by interpolation or extrapolation. While the 

 letters A, B, D and W refer to the observers Archibald, Barnes, 

 De-iuisne and Whetham.
