is situated at the posterior andouter part of the hock, of which it forms the point , and gives attachment to the tendonsof important muscles as well as to powerfulligaments. It articulates in front with theastragalus and below with the cuboid bone andthe cuneiform magnum, on which it rests. Astragalus or Knuckle-Bone.—This is the largest bone in the hock. It is placedin front of the calcis, and from it project for-ward two pulley-like ridges separated by adeep groove. These ridges are received into two corresponding grooves already referred to as existing on the inferiorextremity of the tibia, and the central ridge on the last-named part fitsinto the groove separating those on the astragalus. Together these twobones form the true hock joint, to which the movements of flexion andextension of the limb are for the most part due. The astragalus restsupon the cuneiform magnum, with which it forms a flattened gliding-jointof verv limited movement. Behind, it articulates with the calcis.

Inwardly,it articulates with thecuneiform magnum andthe cuneiform medium. The CuneiformMagnum is a Hat bonecovered on its two surfaceswith cartilage. It occupiesa position between theastragalus above and thecuneiform medium below,and articulates besideswith the cuboid, the cal-cis, and the cuneiformparvum. The Cuneiform Medium is a triangularbone, and, like the mag-num, presents two flat-tened surfaces for articu-lation with the magnumabove, and the largemetacarpal or canon-bonebelow. By smaller articu-lations it is also connectedwith the cuboid and thecuneiform parvum. The Cuneiform Parvum, the smallestbone
