Abstract

In the course of our investigations on the sense of smell, the possibility of obtaining an objective method of measuring olfactory function was carefully considered. With that object in view, the effects of odorous substances on the secretory rate of the parotid glands were investigated, and the results obtained in normal subjects were described in a recently published paper.1 Furthermore, we made studies of the resting activity of the parotid glands and of the effects of an odorous substance, citral, on the volume of secretion of each gland in persons with disorders of the central nervous system. A preliminary report of these investigations is herewith given.

The rate of secretion of the parotid glands in normal persons has been studied and described by Winsor,2 Strongin and Korchin. They showed that the rate of secretion is fairly regular and that the average resting rate in normal persons (uninfluenced by
