The target of the tube is directedtowards the opening of the bowl so as to allow the rays to come second method consists in employing lead sheets with openings cutin them to correspond to the area which is to be exposed to the rays. By the application of plain vaseline to the part exposed directly tothe X-rays, the burning of the patient may be avoided or retarded. Thissubstance, if applied before the exposure, retards the superficial irrita-tion and is specially useful when treating the deeper tissues, and wherethere is no open ulcer. The operator must not expose himself to the action of X-rays and itis advisable that he protect himself by lead lined screens, lead glassspectacles, lead lined gloves, or other Fig. 61—Induction coil—X-ray apparatus Electro-Medicine, Electro-Surgery and Radiology 113 MILLrAMMETER SPARK ROD SHIELO-s^SPARK ROO HANOLE^4*\.
