PARENTERALLY INTRODUCED TRYPSIN 49 



react to very small amounts of phosphorus or hydrazin by 

 suffering marked fatty degeneration of the liver. 39 



The question of " antitrypsin " in the serum has been 

 elsewhere discussed, and the author prefers not to return 

 to this rather uninteresting subject. In what manner 

 trypsin normally gains access to the blood circulation cannot 

 easily be determined with certainty; especially when the 

 body is flooded with the enzyme it has been recognized in the 

 urine. 40 When it is remembered how little we know of the 

 changes many chemically well-defined substances undergo in 

 the animal body, it does not seem at all remarkable that the 

 fate of so indefinite a substance as trypsin remains unknown.
