In oiir view, the material brought forward gives reason for regarding the 

 reversible process, whereby free structural units are transferred from the sur- 

 rounding medium into simple isolated proteins, as a process of protein meta- 

 bolism which, under certain conditions, might give rise to the spontaneous 

 reproduction, variability and increase in complication of a protein; that is to 

 say, to that metaboHsm which is the foundation of biological phenomena.
