![artery; and when the radial lies over the tendons instead of under them, it is still more superficial, and is more exposed to accident. In disarticulation of the metacarpal bone of the thumb, the artery lies close to the joint, and will be cut unless the knife is kept near the bone. Branches of the artery supply the carpus, the metacarpus, and the digits. The posterior carpal branch, h, forms an arch behind the wrist with a corresponding branch of the ulnar artery, and communicated with the posterior interosseous, g: from this carpal arch interosseous arteries are sometimes given to the inner two metacarpal spaces. The metacarpal branch, c, arising here in common with the ]3receding, runs to the second interosseous space, and ends at the front of the space in two branches for the contiguous sides of the fore and middle digits on the dorsal surface. Behind it receives a perforating branch from the deep palmar arch, and in front it communicates with the digital arteries. Dorsal interosseous arteries, f, f, lie over the inner two interosseous muscles, and are derived from the dorsal carpal arch; or they may come from the perforating arteries of the deep palmar arch, as in the dissection from which the Drawing was made. At the cleft of the fingers they give offsets to the sides of the digits, and anastomose with the digital arteries; and if they spring from the dorsal carpal arch, they receive, behind, the perforating arteries from the deejD palmar arch. Dorsal branches of the thumb and fore finger.—Two small branches belong to the thumb, and these run along the metacarpal bone—one on each side, to the last phalanx: the inner one of these is marked d; and the outer one springs from the radial trunk, abont half an inch higher up. There is one branch for the fore finger, which is continued on the radial side of that digit, and supplies the integuments; in this body it is conjoined with the inner artery to the dorsum of the thumb. Both the posterior interosseous artery, g, and the anterior interosseous, h, appear near the wrist; but they belong to the deeper dissection, with which they will be described.](https://iiif.wellcomecollection.org/image/b2122335x_0133.jp2/full/800%2C/0/default.jpg)
