Larynx.—The human larynx is pro- portionally shorter and wider than that of animals. The principal cartilages are those which have been already studied; but there are, besides, small cartilaginous bodies, to which special names have been given : these are the cartilages of Santorini and of Wris- berg. The facets on the cricoid for articu- lation with the thyroid are placed on the small cornua detached from the external face of the cartilage. The thyroid is wide, and protects the anterior face of the larynx; the angle formed by the alse, which is more marked in the male than the female, is very prominent, and is named the pomum Adami. Tije epiglottis is short, broad in its middle, and rounded at its summit, something like that of the Carnivora. The muscles are the same in number and disposition as in these animals; but there is distinguished im oblique arytenoideus—a fasciculus of the arytenoid, which crosses its fellow to form an X in passing from the upper border of one arytenoid cartilage to the lower border of the LUNG OF THE SHEEP; 1, Right lung; 2, Left INFERIOR VIEW. lung; 3, Trachea; 4, Heart; 5, Carotid arteries;
