The monograph is in pamphlet form and is divided into two parts. In the first part the author briefly sets forth and analyzes the experimental evidence bearing on the mechanism involved in the action of roentgen rays and the gamma rays of radium on living tissue. The second part is devoted to a report of experiments carried out by the author to elucidate certain phases of the action of roentgen rays and radium on tissues. He selected the muscular tissue of the heart as an example of a tissue that is known to be resistant to irradiation, and in contrast the eggs of the bluebottle fly, which are distinctly sensitive to irradiation. These experiments were designed to elucidate the effect of varying the intensity of irradiation as affected by temperature, by injury and by irradiation, separately or combined, the effect on radiosensitiveness of injury produced by asphyxia or by roentgen
