Case 460. (Roussy, April, 1915.)

An Arab fell on his knee, one day in the trenches. A contracture of the left arm, with great pain, and a temperature of 38 to 40 degrees, with hemoptysis, developed. This man had been considered tuberculous. One day, however, the thermometer went up to 41 degrees. It was discovered that he took artificial means to push the mercury up, and that the spitting of blood was voluntary. All these phenomena disappeared after he was put in the guardhouse for 24 hours.
