IN THE preceding paper,1 a description is given of the chemical nature and theoretical mode of action of Efocaine. The anatomical effects of this material on animal tissues are described in detail. This paper reports concurrent clinical studies.

The use of this agent in anorectal and perineal surgery was reported by Tucker,2 Gross and Shaftel,3 and Cappe and Pallin.4 These authors concluded that Efocaine is a safe and effective agent for control of postoperative pain.
