The superior extremity, shghtly enlarged, con- stitutes the summit of the calcaneum, and is divided into three parts : a middle, which gives attachment to the tendon of the gastrocnemius : the other, the anterior, is a smooth surface on which this tendon rests when the foot is much flexed ; the third, altogether posterior, also constitutes a gliding surface for the.
