The results show the antagonistic effects between different cathions and anions 

 for wheat-aiiiylase. At last I exerniined Loeb's socalled apparent antagonistic 

 effects between the decomposition products of protein and potassium chloride for 

 wheat-amylase and got the following results. 



10 The antagonistic action between glycocoll 

 and KCl for wheat-amylase 

 Table 11. 



In this case we can also observe the antagonistic effect between glycocoll and 

 KCl for wheat-amylase. 



CONCLUSTON 



From the results we know the antagonistic effects between different salts — of 

 different cathions and same anions as KCl and CaCl^, NaCl and CaCl^, NaCl and 

 KCl or CaCl^ and JilgCl^, and of d'fferent anions and same cathions as KCl and 

 K^SO^, KNO3 and K.^SO^^ and of different cathions and different anions as 

 K^SO^ and MgCL or CaCl^ and RlgSOj^ — for amylase of wheat-seedling and 

 for Takadiastase. Farther more the apparent antagonistic effect is observed 

 between glycocoll and KCl for the same enzym.
