The total salivary production was collected by allowing the saliva to drain into a 50 cc. beaker over a 5 min. period after the establishment of constant drainage from the mouth. Using the method for determining the resting volume flow of salivary secretion, evidence was obtained that the mean of a sufficient number of detns. represented a value which was reproducible and characteristic of the individual. The distribution of the mean of 2 values of a limited number of subjects was skewed. The modal value was about 0.24 cc./min. The lowest mean of 2 values obtained was 0.08 cc./min. and the highest, 0.88 cc./min.
