The apparatus used for local treatment of acute anterior urethritis is an ordinary douche-can, four feet of indiarubber tubing, a clip, and a glass nozzle, which is fined down to a blunt point, and is flattened. The can is suspended five or six feet above the patient, filled with a pint of water which is a little too hot for the hand to bear with comfort. By the time the fluid has reached the nozzle and one is ready to begin, it will not be too hot.
