III. Action on Starch. This action of the pancreatic juice 

 seems to depend on a separate ferment (Amylopsin), and with the 

 exception that it is much more rapid and energetic, and is said 

 to affect raw as well as boiled starch, its action seems to be iden- 

 tical with that of the saliva. This power is found to exist in the 

 extract of the gland, whether it has been removed from a fasting 

 or from a recently fed animal, and therefore does not depend on 

 whether the gland is engaged in active secretion or not.
