The effect of salicylic acid upon autolysis. 



By L. B. STOOKEY. 



[From the Physiological Laboratory, Medical Department, University 

 of Southern California^ 



The liver, kidney, spleen and muscle taken from dogs which 

 had received subcutaneously doses of sodium salicylate (o. 1 gram, 

 in 1 per cent, solution, per kilo of body weight) daily, during a 

 period of ten days, showed rates of autolysis greater than those 

 observed in the same organs taken from normal dogs. 



The influence of other drugs upon autolysis is being investi- 

 gated.

On the synthesis of protein through the action of trypsin. 

 By ALONZO ENGLEBERT TAYLOR. 



[From the Laboratory of Pathology, University of California.^ 



The application of the theory of thermodynamics to general 

 chemical reactions has resulted in the definition of the following 

 principles, all of which have been confirmed by experiment as well 

 as by mathematical considerations : 



All chemical reactions are reversible reactions ; 



All chemical reactions progress to an equilibrium in the system. 



There is in every chemical reaction a driving force and an in- 

 ternal chemical resistance. 



Catalytic acceleration operates through a reduction in the in- 

 ternal chemical resistance ; since the driving force is unaltered, the 

 station of equilibrium is attained more quickly, that is, the experi- 

 mental velocity of the reaction is increased. 



The catalytic acceleration operates in either direction of the 

 reaction ; no matter in which direction the reaction may happen
