Excerpt from Animal Chemistry, Vol. 2 of 2: With Reference to the Physiology and Pathology of Man The Saliva. The saliva is a peculiar fluid, secreted by the parotid, submaxillary, and sublingual glands, and conveyed from them by certain ducts into the cavity of the mouth, where it becomes mixed with the buccal mucus. It may, however, be obtained in a state of purity by collecting it as it flows from one of the ducts. The following observations respecting the secretion of the saliva were made by Mitscherlich, 1 on a person with a salivary fistula, in whom the saliva could be collected directly from Stenos duct. He found that there was no flow of saliva while the muscles of mastication and of the tongue were in a state of perfect repose, and all nervous excitement avoided. He likewise observed that, during the acts of eating and drinking, (especially at the commencement, ) the secretion was abundant, being proportionate to the stimulating nature of the food and to the degree it was masticated. From two to three ounces of saliva were collected from one of the parotid glands in the course of twenty-four hours. It is usually supposed that about ten or twelve ounces of saliva are secreted daily, but accurate observations are still required on this subject.
