Its lower part bears a small projection (rudimentary acromion). The anterior border is strongly convex in profile, sinuous when viewed from the front, and thick and rough in its middle. The posterior border is wide, shghtly concave, and bears a rough outer lip. The vertebral border is convex, and the cartilage is not so extensive as in the horse and ox. The anteri- or angle is thin and bent medially a little. The posterior angle is thick and is about. 9 f Fig. 183.—Left Sc^pl-la op Pig; Lateral View. a, Anterior angle; b, posterior angle; c, anterior border; d, posterior border; e, neck; /, glenoid cavity; p, tuber scapuliE: 1, spine; 2, tuber spinae; 3, acromion; 4, supraspinous fo-ssa; 5, infraspinouj fossa; 6, cartilage. a right angle. The neck is well defined. The rim of the glenoid cavity is rounded and not notched. The tuber scapulae is just above the antero-me'dial part of the glenoid cavity and bears no cUstinct coracoid process; it unites with the rest of the bone at about one year. The humerus has an appearance in profile somewhat like an italic / minus the cross-bar; this is due to the marked backward and forward inclination of the prox- imal and distal ends respectively. The shaft is decidedly compressed from side to side. The medial surface is extensive and flattened; it is separated from the anterior surface by a distinct border, and bears no teres tubercle. The musculo- spiral groove is shallow. The deltoid tuberosity is small, and there is a larger rounded eminence midway between it and the lateral tuberosity. The nutrient.
