SALTS OF THE GLOBULINS : MIGRATION VELOCITY OF THE PRO- 

 TEIN IONS ...... .121 



Hardy's researches on combination of proteins with acids and 

 alkalis. Direct determination of the mobility of globulin ions 

 by migration experiments. Its calculation from conductivity 

 data. Agreement of the values thus obtained. Effect of 

 valency on the mobility of protein ions. Determination of 

 mobility of protein ions by Pauli and Sven Oden, also by cir- 

 cuits containing albumin salts. Robertson's work on the 

 electro-chemical equivalent of casein. Agreement with the 

 constitution of the caseinates previously set forth.
