. The horse, its treatment in health and disease with a complete guide to breeding, training and management . Fig. 304. —Os or Large PasternBone dyles, already spoken of as existing on the lower end of the canon, arefitted to form a joint of considerable extent of motion. The lower ex-tremity is small, and divided by a superficial groove into two Bones (lO, fig. 302).—These are two small floating bonessituated behind the inferior extremity of the canon. They are somewhattriangular in form, with their bases directed downward, and are clo.^elyunited one to the other. In front they are covered with cartilage, andarticulate with the condyles of the canon bone, thus forming part of the THE FORE LIMB 199. fetlock joint. Behind they arc covered with fibro-cartilage, and byapposition form a groove over which the great flexor tendon of the footplays like a rope over a pulley. On tlie outersides, from the apex downward, a roughenedgroove gives attachment to the two branchesof the suspensory ligament. The under sur-face of the base is also roughened, and fromit proceed short strong ligaments {inferior-sesamoid), which attach the bones to the pos-terior surface of the large and small Coronse (%. 305), small pastern, orsecond phalanx, is a short bone placed be-tween the large pastern and the os pedis, orfoot-bone. One-half of it is enclosed by thehoof, and the rest forms the region of thecoronet. Its upper extremity presents two OsNavicuiare J^l _ . (Anterior Aspect) shallow depressions, with which the two con-dyles of the lower end of the large pastern articulate. The lower end,like that of the sutfraginis, is divided by a shallow groove into two con-dyles,
