The lower end of the trachea, the bronchi, the vagi, and the left recurrent nerve, are all more or less surrounded by lymph glands, which, when enlarged, may exert injurious pressure upon them. THE HEART AND GREAT VESSELS. Viewed from the front, the outline of the precordial area, like that of the peri- cardial sac, is roughly triangular, the base of the triangle being below and the apex above. The boundaries are delineated upon the surface as follows:â The right side of the triangle, formed by the right atrium, is indicated by drawing a line slightly convex laterally from the superior end of the third to the sixth costal cartilage, a finger's breadth from the edge of the sternum; the curve attains its maximum opposite the fourth intercostal space, where it reaches one and a half inch from the median plane. The base of the triangle, formed by the mar go acutus of the right ventricle and to a very slight extent by the apical portion of the left ventricle, is almost horizontal, and corresponds to a line drawn from the inferior extremity of the right side of the triangle to the apex of the left ventricle, which lies behind the fifth left intercostal space, three and a half inches from the median plane, and half an inch medial to the mid-clavicular line. The base line crosses the xiphoid process at its junction with the body of the sternum. The left side of the triangle, formed by the margo obtusus of the left ventr
