y its largerounded head, the broad articular facet on its upper convex surface, and by thetwo articular facets separated by a deep groove on its under concave surface. Itpresents six surfaces for examination. The superior surface presents, behind, a broad smooth trochlear surface, forarticulation with the tibia; it is broader in front than behind, convex frombefore backwards, slightly concave from side to side. In front of the trochleais the upper surface of the neck of the astragalus, rough for the attachment ofligaments. The inferior surface presents two articular facets separated by a deepgroove. The groove runs obliquely forwards and outwards, becoming graduallybroader and deeper in front: it corresponds with a similar groove upon the uppersurface of the os calcis, and forms, when articulated with that bone, a canal, filledup in the recent state by the calcaneo-astragaloid interosseous ligament. Of thetwo articular facets, the posterior is the larger, of an oblong form, and deeply

H3 concave from side to side; the anterior, although nearly of equal length, is nar-rower, of an elongated oval form, convex longitudinally, and often subdividedinto two by an elevated ridge; of these the posterior one articulates with the lesserprocess of the os calcis; the anterior one, with the upper surface of the calcaneo-scaphoid ligament. The internal surface presents at its upper part a pear-shapedarticular facet for the inner malleolus, continuous above with the trochlear surface;below the articular surface is a rough depression, for the attachment of the deep portionof the internal lateral ligament. The external surface presents a large triangularfacet, concave from above downwards, for articulation with the external malleolus;it is continuous above Avith the trochlear surface: and in front of it is a rough de-pression for the attachment of the anterior fasciculus of the external lateral ligament.The anterior surface, convex and rounded, forms the head of the astraga
