One of these diagrams presents a front and the other a back viewof the larynx or vocal box. The bone of the tongue is seen, likehalf of a hoop marked 8, in both plans. 2 is the front of the thyroidcartilage, felt under the skin — protruding in the form of an irregu-lar tumor. The wind-pipe is the tube at the bottom of each 256 BOOK. The vocal cords — the membranes which vibrate to produce sound,as the current of air rushes by, are concealed, being placed the remarks in the text, together with the references, a verycorrect idea will be formed of the structure of this curious blowing through the wind-pipe of almost any animal, soon afterit is shun, provided the larynx has not been injured, the vocal cordsmay be put in motion, and the sound which is produced will bearconsiderable analogy to the natural voice of the animal. Within the larynx, and consequently below the valve,are four delicate membranes, two on each side, put uponthe stretch — being in fact, like shelves, — their thinedges nearly meeting from the opposite sides, so that thereis scarcely any space between them. These are the vocalcords. When the air rushes ou
