CHEMICAL DYNAMICS OF ANIMAL NUTRITION 153 



The following experiments have been carried out with 20 c.c. 

 liquid. 



Acetic acid. 



We see from these figures that both acetic and lactic acid exerts a 

 very powerful accelerating influence on the rate of autolysis, especially 

 the latter acid. Lactic acid accelerates the autolysis more than does 

 sulphuric acid in the corresponding strength of solution. This is 

 important in view of the fact that lactic acid is known to be formed at 

 times within the organism. 



Series V (7z). Influence of ammonia and trimethylamine on autolysis. 



In the following experiments the liver was incubated with the 

 alkaline solutions in corked flasks. The autolysis was determined by 

 estimating the nitrogen in the filtrate from coagulum in a portion before
