AN ADVERTISEMENT OF THE WESTINGHOUSE ELECTRIC & MFG. CO. * PITTSBURGH, PA. ... but she will never forget the happiness it brought N OW Mother knows that Danny's broken arm will heal perfectly. In a few short weeks she will watch him play, his arm and hand as sure and strong as if the accident had never happened. Such is the verdict of the roentgenologist - the physician who special izes in X-rays. A strange word, roentgen ologist - but not half so strange as the science he serves. He deals with shadows cast by invisible rays upon a photo graphic film - shadows that are confusing and meaningless to others, but as readable to him as print on a page. Nor does their story tell only of broken bones. Because of the roentgenologist's skill, thou sands now recover from scores of diseases that were baffling and hopeless not very long ago. Tuberculosis has lost its dread. The fight against cancer gains ground every year. Westinghouse scientists and engineers have co-operated with leaders in the profession for many years, helping to develop the complex and in tricate apparatus they must have for this work. Now better, more powerful apparatus makes a picture in the flash of an eye, treats cancer with voltages as high as lightning. Yet it is so safe and precise that it can be controlled with the ease that is yours when you tune your radio. In X-ray, as in so many other fields, Westinghouse research and skill are directed to one pur pose-to make the tremendous force of electricity the more willing servant of humanity. ® Westinghouse "Mention the Geographic-It identifies you."
