The inferior surface is convexand rough, and bounded posteriorlyby the two inferior tuberosities,of which the internal is broad andlarge, and the external smaller andprominent. The external surfaceis convex and subcutaneous, andmarked towards its anterior thirdby two grooves, often separated bya tubercle, for the tendons of theperoneus longus and brevis. Theinternal surface is concave andgrooved, for the tendons and vesselswhich pass into the sole of the the anterior extremity of thissurface is a projecting process (sus-. * The dorsal surface of the left foot. 1.
