The rate is practically identical for the two sides. The rate o 

 autolysis does not appear, therefore, to be influenced by activity. 



Experiments were also made on the rate of autolysis of fresh and 

 frozen meat. No difference could be detected. 



In the case of frogs' muscles, tetanization appeared to exert an 

 inhibitory influence on autolysis. The difference was, however, but 

 slight. No precautions were taken in these cases for asepsis, so that 

 no definite conclusions could be drawn. 



Series IX. The comparative rate of autolysis in different tissues. 



The blood does not autolyse to any appreciable extent in 24 hours, 

 either when incubated with ten times its volume of water, or ino'5 per 

 cent, ammonium oxalate solution. The thyroid gland also autolyses 

 but to a very slight extent in 24 hours. 



In the following experiments, the relative rate of autolysis of 

 4 grams from each organ in 24 hours was determined. Toluol was 

 employed as an antiseptic. 



Organs taken from two different dogs, given in table under 

 columns I and II. In animal I, autolysis lasted 24 hours ; in animal 

 II, 20 hours.
