The speed of eating, the secretion of the parotid gland and the amylase activity of the excreted saliva were studied in animals lacking their molars for 6 mth. The absence of mastication caused an increase of the speed of eating, but a decrease of the salivary excretion of the parotid gland and of the amylase activity of the excreted saliva. The conclusion is drawn that mastication is a necessary factor both in the initiation of the amylase synthesis and in the maintenance of the physiologic condition of the parotid gland.
