    deltoid ligament is ossified, and enters into the com¬ position of the surface described, which, in consequence of the upward extension of the glenoid cavity forms with the latter a continuous excavation for the head of the humerus. The anterior extremity of the cora¬ coid process is thin and sharp, being, as it were, be¬ velled off by the presence on its inferior and outer as¬ pect of an articulating facet, which is nearly as large as the little finger-nail, and similar to the one last described both in surface and office. Between the posterior edge of this surface and the inner projecting margin of the glenoid cavity there is an interval of only two lines. Humerus. (PI. i. fig. i.)—The breadth of the arti¬ cular portion is much increased in all directions, with a considerable diminution of its natural amount of con¬ vexity. The cartilage is wanting : the surface beneath is here and there slightly rough. The cortex is deli¬ cately thin, and with a little pressure might, in some places be cut with a knife. The mesh-work of the cancellated texture is, as it were, opened out, and filled with medulla, preternaturally red. The circumfer¬ ence of the anatomical neck is overlaid by a cincture of osseous growth, analogous in form to that encircling the glenoid cavity of the scapula, and like it, too, spongy in texture. The chief portion of this substance is around the lower third of the cervix, giving in con¬ sequence to the sawn surface of a vertical section the
