CONSTANT FOR ELECTROLYTES—HEBB. 419 
The following table gives the values of the constants k and / 
given in table I. together with the values of m and i—z. e., the 
depressions of the freezing-point due to a gramme-molecule of 
the undissociated salt, and that due to a gramme-ion of the dis- 
sociated salt—as obtained from them.
