Section of the ulna C» Interosseous ligament D. Pronator quadratus muscle E. United radius F. Ulna united by ligament. Fig. of the cranium,^ and a portion of bone removed bythe trephine. A. Os frontis B. Parietal bone C. Large aperture in the skull remaining unfilled, except at its edges, although it had the appearance of being anaccident of ancient date. D. Fracture ununited.
