N2  - The primary digestion is accomplished through the action on the foodstuffs of certain ferments. The action in the case of each and all of these ferments is that of hydrolysis. Different foods require for their hydrolysis the attack of different sorts of ferments, and the organism is fortunately provided with a variety of these secretions.It is somewhat remarkable that the several ferments operate unfavorably on each other. This is partly owing to the nature of the ferments and partly owing to the conditions under which they are secreted. Thus, ptyalin, an important factor in the digestion of starch, acts for the most part in the stomach previous to the free secretion of acid gastric juice, which inhibits the ptyalin; and the gastric ferments, in their acid medium, are in turn made inactive through the secretions entering the duodenum. It will thus be seen that the administration of digestive ferments as
