    Figure—Irregular. Divis^ion—Into body and tuberosity. The body is the broad or inferior part. It is irregularly convex externally, Avliere it is joined with the tuberosity: concave and expanded internally, where it presents four siu'faces for arti- culation with the astragalus, with asperous interspaces for liga- ment. The inferior part of the body has a narrow articulatory surface, by which it articulates also with the cuboid bone. The tuberosity, the projecting part behind, is oblong, flat- tened on its sides, and exhibits a thick, tuberous termination, into which is implanted the tendons of the gastrocnemii. The exter- nal side is flattened and roughened by ligamentous connexion; the internal is smooth, and inclines to conca^dty, by which a space is left which gives passage to the tendon of the flexor pedis. CUBOID BONE. (oS CUBOIDES.) Situation. Outer pai*t of the hock. Form. Oblong, from back to front. Division. Into external, internal, superior, and inferior surfaces. The external surface, broad and irregularly curved, is roughened by ligamentous adherence.— The internal surface, irregularly excavated and asperous, exhibits three places of articulation: one, posteriorly, for the great cuneiform; the other two smaller, one anteriorly, one posteriorly, for the middle cuneiform bone. The superior surface has two articulations, with a little pit be- tween them; one for the astragalus, a larger one for the os calcis. The inferior surface presents two articulatory places; one for the external splint bone, the other for the cannon bone. THE LARGE CUNEIFORM BONE. (oS CUNEIFORME MAGNUM.) Situation. Immediately underneath the astragalus. Figure. Triangular : broadest side turned forwards; salient angle, backwards. Flat above and below. Division. Into superior and inferior surfaces, sides, and angles. The superior surface is entirely articulatory, with the exception of a little rough groove running to its middle from the outer side, which terminates in the medullary hole : it is adapted to the under part of the astragalus.—The inferior surface is very similar in appearance to the superior, except that it is flat, or rather inclines to convexity: it articulates with the middle cuneiform, and also, next the internal angle, with the small cuneiform.— The salient or posterior angle has on its external side a surface for articulation with the cuboid. Connection. With the astragalus, cuboid, middle and small cuneiform bones.
