Experiments The subjects were medical student volunteers. With the area under lidocaine (Xylocaine) hydrochloride anesthesia, burn blisters were produced by contact with the end of a weighted copper cylinder, 1 cm. in diameter, through which water from a thermostatically controlled bath vigorously recirculated. Twelve to sixteen burns
