 PHENOMENA 



1. The Oscillation of Protoplasm Structure 



In studying the inactivating progress of phage or of rennin by 

 the addition of inactivating agents such as antibody or tannin, we 

 have found that the inactivation occasionally proceed in an extremely 

 irregular way (131). In Fig. 26 is shown an example of an irregular

 maldehyde, and in Fig. 27 a similar irregular inactivation progress of 

 rennin by tannin. 



In these examples, it is clearly shown that. the inactivation proceeds 

 with remarkable oscillations as if it were a physical phenomenon,.
