The following summary comprises a brief review of what medicine has been doing in the recent past: Radium.--This element was discovered about fifteen years ago by Professor and Mme. Curie. It possesses the wonderful property of giving out inexhaustible stores of energy. It virtually possesses the property of perpetual motion. Professor Becquerel was the first one to suggest that it might possess therapeutic or healing powers. The suggestion came to him in a curious way. He carried a tube of radium in his vest pocket and was severely burnt as a consequence. The incident suggested to him that, if radium could attack healthy tissue in such a short time, it should be able to similarly attack diseased tissue. Experiments were soon instituted, and are still being conducted to exactly define its curative value and scope. It was hailed as a cure for cancer and other serious conditions, but we have found that it is not a cure for these ailments. It is, however, exceedingly valuable in the treatment of certain skin diseases. In lupus, epithelial tumors, ulcers, papillomata, angiomata and pruritus, it is being widely and successfully used. It was later discovered that it can quickly kill disease-producing bacteria. It is also well known that it will efficiently purify water. X-Ray Treatment and X-Ray Diagnosis.--Professor Roentgen gave to the world an exceedingly valuable discovery in the X-Ray. He discovered that a certain form of electrical energy, when applied in a certain way, would produce shadows that differentiated between a certain degrees of opacity. For example, it would, if directed upon the human hand, produce shadows that clearly indicated whether the substance through which the rays passed was bone or muscle. The chief value of the X-Rays has been found to be this property rather than any healing value which has been attributed to them. The fact that these shadows can be photographed has rendered them of supreme value in surgery and medicine. Previously it was essential that the surgeon should depend upon his own diagnosis, upon what he could learn from his sense of touch and from surrounding conditions. With the X-Rays at his disposal he can quite eliminate the personal equation. His pictures are precise and mathematically accurate; he can prove the truth of his diagnosis before he cuts. We can take pictures of fractured bones and from what we learn we can immediately tell how they should be set to attain the very best results. We can actually tell if there is a stone in the kidney before we subject the patient to a serious operation. We can actually take pictures of the stomach at various stages of digestion and tell what disease affects the individual with a degree of precision that was not possible before the X-Rays were introduced. These examples only suggest its use. There are a multiplicity of uses for these as yet unknown rays which have greatly aided in diagnosis and consequently in successful treatment.
