The shorter has an ob-long convexity on its opposing surface, with transversewhich convexity and ridges correspond to groovesin the fenestra of the longer blade. The head beingperforated, the short blade is passed internally as far as pOBsible, toward the base of the cranium, and tlm long blade externally. These blades being one inob in width, give a strong purchase on the occipital bone. Fig. Cran
