AmongQuains 100 collected cases 77 were due to fatty of the patients were beyond years of age, and suddendeath occurred in 71 per cent. The site of rupture was as follows:Left ventricle, 55; right ventricle, 7; right auricle, 3; left auricle, may be complete or incomplete. It is slightly morefrequent in males. In 18 of LetuUes 110 cases, multiple rupturewas found. Occasionally rupture occurs in apparently healthyyoung people as the result of coronary thrombosis.^ Quainscases included two between the ages of ten and twenty. Rupture ? Klingmann: New York Med. Jour., 190S, p. Fig. 69.—Gumma of the Myocardium. A larfcc, firm, nodular mass is seen in the septum below the aortic valves which bulgesforward into the ventricle. Another mass is seen in the wall of the ventricle. These masseswere firm, .slightly elastic, grayish in color, and upon microscopic examination showed typicalgummatous structure. The heart is that of a patient aged thirty-one years, who had contracted syphilis eightyears before. Three years previous to admission he had been incapacitated for three daysby an inflammation of the heart. Six weeks before admission he had had fugacious painsand less of power in the right hand. A few days afterward he had a syncopal attack while atwork, following which he developed headache, weakness, numbness of the legs, and to the hospital he was found to have a right-sided hemiplegia. On auscultationa mitral systolic murmur was noted. During his three months stay in the hospital he hadhemoptysis and car
