Tumors.—Tumors of the character of fibromata and fibro-sarcomata may arise upou the endocardiüm as well as on the peri-cardium and epicardium. According to Kitt, the tumors take theirorigin from the sub-endocardial tissues, are commonly pedunculate,and connected with a trabecula, papillary muscle, or tendon. Tumorswhich project into the cardiac cavity may reach the size of the fist. 3*40 NOTEWORTHY ORGANIC DISEASES Myocardiiim.
