Directions are given for the fabrication, cleaning, and sterilizing of a modified CarlsonCrittenden parotid fluid collecting device that has been use-tested by the authors in the collection of over 40,000 specimens. It has served particularly well in prolonged collections made with exogenous stimulants. The size of the device is such that it is easily adapted for use in making collections from dogs and other large experimental animals. (Author)
