. The comparative anatomy of the domesticated animals. Horses; Veterinary anatomy. lOi THE B0NE8. Fig. 65. Body.—Slightly arched and flattened before and behind, it presents for study two faces and hvo borders. The anterior face is convex and perfectly smooth. The posterior, a little concave from one extremity to the other, offers : 1. Near the external border, a triangular surface, covered with asperities, elongated vertically, very narrow, commencing near the upper fourth of the bone, and terminating in a fine point towards the lower fourth ; this surface is brought into contact with the anterior face of the ulna by an interosseous liga- ment, which is completely ossified before the animal reaches adult age. 2. Above, there is a wide, trans- verse, but shallow groove, which aids in forming the radio-ulnar arch, and shows, near the point where it touches the preceding surface, the nutrient foramen of the bone. ;3. Near the internal border, and towards the inferior third, there is a vertically elongated and slightly salient eminence for insertion. The two borders—external and internal—are thick and rounded ; they establish an insensible transition between the faces. Extremities.—The superior is larger thau the inferior. It has : 1. An articular surface elongated from one side to the other, concave from before to behind, wider within than without, and moulded to the articular sur- face of the inferior extremity of the humerus ; there is also seen, outwardly, a double depression {glenoid cavities), which receives the two lips of the external trochlea; in the middle, an antero-posterior ridge, which is received into the internal trochlea ; within, an oval cavity corresponding to the internal border of the former. 2. The external tuberosity, placed at the extremity of the great diameter of the articular surface ; it is prominent and well detached. 3. The internal or bicipital tuberosity—a large, very rugged, and depressed process, situated within and in front
