(2) The small volar muscle is the extensor digiti quinti proprius; it entls by a long tendon on the lateral aspect of the fifth tligit. The supinator, when present, is a pale, thin muscular slip which arises on the lateral bonier of the radius just above the interosseous space, extends medially and downward across the dorsal surface of the bone to its medial border, where it blends with the radial head of the deep flexor. The pronator teres is a delicate, fusiform muscle which lies along the medial surface of the elltow and proximal part, of the forearm. It arises from the medial ejiicondyle and Collateral ligament of the elbow and is inserted by a thin tendon to the medial border of the radius about its middle. The flexor carpi radialis is well developed. It arises on the medial epicondyle of the humerus, and is inserted into the third metacarpal lione. The flexor carpi ulnaris is narrow and has no ulnar head. It runs obliciuely down the back of the forearm in the furrow between the superficial and deep flexors of the digit. It arises from the medial epicondyle of the humerus anil ends on the accessory carpal bone. The ulnaris lateralis (M. extensor carpi ulnaris) is covered Ijy a tendincjus Ijantl, which is a thickened part of the fascia of the forearm and extends from the lateral epicondyle to the accessory carpal bone and lateral aspect of the carpus. The Ijelly of the muscle is round: its ten- don of insertion perforates this band in the distal part of the forearm and ends on the proximal end of the fifth metacarpal bone. The superficial digital flexor arises from the medial e]iicondyle of the huincrus and consists of two parts. The tendon of the .superliciul head passes down behind the pos- terior annular ligament of the carpus (bound dowii by a special annular ligament), forms a ring at the fetlock for a tendon of the deep flexor, and entls by two branches on the seco
