Within the circumference of the outlet, but ata lower level, two pale-red, smooth ledges are visiblerunning from before backwards, and joining the lowerpart of the arytenoid cartilages. These are the ven-tricular bands; each of them overhangs a cavity (ven-tricle of the larynx), of which it forms the upper bor-der. The mouth of the cavity cannot, however, bedistinctly seen without slanting the mirror to one in the interior of the larynx (*.*., in the centre ofthe image), when it is in a state of repose, the white. Fig. Glottis. (Seen from above during the Emission of a Low Chest-Note.) glistening vocal cords can be seen running in the samedirection as the ventricular bands, but nearer the mid-dle line. Sometimes they are not seen until the actof phonation is performed, when each seems to shootout from under the corresponding ventricular aperture between the vocal cords is wider behindthan in front, and forms, as already said, a triangularspace (see Fig. i), the apex of which is at the anteriorpart where the vocal cords join each other, whilst thebase is behind, between the arytenoid cartilages. Ifthe breath is drawn in, as in quiet inspiration, the cordsare seen to move a little way apart from each other, THE 33 and the base of the triangle widens out. If a deepbreath is taken, the cords separate still more, whilst inforced or gasping inspiration they are drawn widelyapart, so that a glimp
