![the ulnar artery. The two deep ulnar veins, commencing thus at the inner side of the superficial palmar arch, pass in front of the wrist, where they communicate with the interosseous and the superficial veins; then proceeding upwards along the inner side of the fore-arm, one on each side of the ulnar artery, they receive several branches from the neighbouring muscles; and, lastly, being joined by the veins which accompany the interosseous and ulnar recurrent arteries, unite with the deep radial veins to form the vena? comites of the brachial artery. The interosseous veins consist of two sets (anterior and posterior), corresponding to the arteries with which they are associated. The anterior interosseous veins commence in front of the wrist-joint, where they communicate freely with the deep radial and ulnar veins. In their course upwards they are joined by several small branches, and are connected at the upper part of the fore-arm with the posterior veins by means of branches which pass through the interosseous membrane near the elbow-joint; after being joined by the posterior interosseous veins, they end in the venae comites of the ulnar# artery. The veins which accompany the posterior interosseous artery, pre- viously .to passing from behind to join with the anterior veins, commu- nicate by their smaller branches with the ulnar cutaneous veins, and through branches accompanying the recurrent interosseous artery, with the cephalic vein. The small branches which unite to form the deep radial veins run along the interosseous muscles in the palm of the hand; they are united in front with the digital veins previously described, and, at each end of the interosseous spaces, are connected by perforating branches with small veins situated on the back of the hand ; by uniting across the bases of the metacarpal bones, they form a double venous arch corresponding with that formed by the radial artery. These deep palmar veins communicate on the inner side with the superficial arch of veins, and on the outer side end in the companion veins of the radial artery. The deep radial veins, in passing upwards to the fore- arm, receive at the wrist a dorsal branch, and one which passes over the small muscles of the thumb, with the superficial volar artery; then pursuing the course of the radial artery, they are joined by small veins from the surrounding parts, and end in the venae comites of the brachial artery. The two brachial veins, [venae brachiales,] resulting from the union of the deep ulnar and radial veins just described, follow, like the several vessels of the same class, the course of the artery with which they are associated. They are joined in their progress, from the bend of the elbow upwards on the arm, by the veins which accompany the branches of the brachial artery, namely, the anastomotic and the two profunda arteries of the arm. At the lower margin of the axilla, the brachial veins unite to form the axillary; not unfrequently, how- ever, one of them will be found to come forward and unite with the basilic, which soon becomes continuous with the axillary vein. Between the several veins of the upper limb hitherto described, numerous connexions exist in their whole course.
