ne side of the tube is in-cluded in the illustration. There was com-plete necrosis of muscle tissue over a zone4 mm. in diameter, surrounded by an areaof edema, degeneration of muscle fibers, andlymphocytic infiltration over an additionalzone, about 2.5 mm. in width. The total area The Action of Buried Tubes of Radium Emanation 539 of radiated tissue in this case was about 9mm. in diameter. A still weaker radium tube, 0.2 mc, wasplaced in the center of a rats testes and leftthere for twenty days. The histological pic-ture is given in Plate III. The central areaof necrosis was about 4 mm. in diameter.The peripheral portion of this zone showed Plates IV and V is not exactly comparableto the preceding sections, since the radiumtube was separated from the tissues by thethickness of a rats calvarium. The sectionis presented because it shows in a very strik-ing manner the leukocytic infiltration whichthe tissues set up in an attempt to localize theirritant. The tube contained 1.2 mc. of ra-
