    gether by passing beneath the supinator longus [to the back of the forearm. The position of four nerves can be readily remembered by the following Rule: The radial nerve lies to the radial side of the radial artery; the ulnar nerve to the ulnar side of the ulnar artery, and the tibial nerves (both anterior and posterior) to the fibular side of the tibial arteries ; the forearm and leg being thus the opposites of each other]. The radial artery lies upon (1) the tendon of the biceps (though this will depend upon the point at which the bifurcation takes place) ; (2) the oblique fibres of the supinator brevis ; (3) the insertion of the pro- nator teres ; (4) the radial origin of the flexor sublimis; (5) the flexor longus pollicis; (6) the pronator quadratus, and (?) the end of the radius.1 It has two venae comites in close relation with it and gives the following branches:— Branches.—1. The radial recurrent runs transversely beneath the supinator longus and gives ascending and de- scending branches, the ascending anastomosing with the superior profunda branch of the brachial artery. 2. Muscular branches are given off at various points to the adjacent muscles. 3. The supeificialis volse arises near the root of the thumb, and is of very variable size. It runs forward, and generally beneath some of the fibres of the muscles of the thumb, to complete the superficial palmar arch formed by the ulnar artery. 4. The anterior carpal is a small branch which runs across the wrist beneath the deep tendons to join a corres- ponding branch of the ulnar artery. Surgery (Fig. 8, p. 39).—The radial artery is readily tied, about an inch above the wrist, by an incision one inch and a half long, placed midway between the tendons of the flexor carpi radialis and supinator longus, when the vessel will be found lying immediately beneath the deep fascia with the venae comites in close connection, but with no nerve near. The artery may be exposed in the upper part by an incision two inches long at any point in a line drawn from the centre of the bend of the elbow to [midway between] the styloid process of the radius [and the tendon of the flexor carpi radialis], the knife going at once down to the supinator longus, which must then be carefully 1 The posterior relations of the radial artery are simply the mus- cles attached to the radius iu their order from above downwards.
