ON THE TOXIC ACTION OF DISSOLVED SALTS AND 
THEIR ELECTROLYTIC DISSOCIATION.* 
Louis KAHLENBERG and RoDNEY H. TRUE, 
THE THEORY OF ELECTROLYTIC DISSOCIATION. 
During the last decade work in physical chemistry has been 
characterized by a thorough and systematic study of solutions 
from both theoretical and experimental points of view. As a 
result of the activity along this line our knowledge of the nature 
of substances dissolved in various solvents has been greatly 
extended. In 1887 van’t Hoff,? basing his argument upon the 
osmotic experiments performed by Pfeffer? ten years earlier, was 
enabled to show almost a complete analogy between the behavior 
of solutions and gases. This analogy grows out of the fact that 
when the volume of a solution and its osmotic pressure are taken 
into” consideration the same laws hold as in the case of gases 
hen ‘the volume of the gas and its pressure are considered. So 
Meee i is the analogy that, considering the temperature — constant,
