iformbone. It is situated at the upper and inner side of the carpus. The superiorsurface presents an internal, rough, non-articular portion; and an external orarticular portion, which is convex, smooth, and separated from the lower endof the ulna by the inter-articular fibro-cartilage of the wrist. The inferiorsurface, directed outwards, is concave, sinuously curved, and smooth, for articu-lation with the unciform. Its posterior or dorsal surface is rough, for the attach-ment of ligaments. Its anterior or palmar surface presents, at its inner side, anoval-shaped facet, for articulation with the pisiform; and is rough externally, forligamentous attachment. Its external surface, the base of the pyramid, is markedby a flat, quadrilateral, smooth facet, for articulation with the semi-lunar. Theinternal surface, the summit of the pyramid, is pointed and roughened, for theattachment of the internal lateral ligament of the wrist. 110 OSTEOLOGY. ! 94.—Bones of the Left Hand. Dorsal Surface.

CARPUS. 111 To ascertain to which hand this bone belongs, hold it so that the base isdirected backwards, and the articular facet for the pisiform bone upwards; theconcave articular facet will point to the side to which the bone belongs. Articulations. With three bones: the semi-lunar externally, the pisiform infront, the unciform below, and with the triangular inter-articular fibro-cartilagej which separates it from the lower end of the ulna. The Pisiform bone may be known by its small size, and from its presenting asingle articular facet. It is situated at the anterior and inner side of the carpus,is nearly circular in form, and presents on its posterior surface a smooth, ovalfacet, for articulation with the cuneiform bone. This facet approaches the supe-rior, but not the inferior, border of the bone. Its anterior or palmar surface isrounded and rough, and gives attachment to the anterior annular ligament. Theouter and inner surfaces are also rough, the former being convex, the latte
