Stolnikow* has stated that a very small amount of atropine sul- 
phate is without influence on the ferment power of a glycerine ex- 
tract of pancreas, but that large amounts of the alkaloid salt, con- 
siderably diminish the proteolytic action of the ferment. 
Strychnine sulphate and Brucine sulphate. 
These two alkaloids produce more marked effects on the ferment, 
than the preceding. Of the two, as the results show, strychnine is 
more powerful in preventing proteolytic action.

This alkaloid causes a complete stopping of proteolytic action; 
nearly so, even when present to the extent of only 0°5 per cent.
