In the application of the instrument the first greatdifficulty to overcome is the illumination of the pharynx; the seconddifficulty is to learn to manipulate the mirror in such a way as todisplay the larynx, or any part it is desired to see, to the best ad-vantage (Fig. 16). It must be remembered that the image of the Fig. 16.*. parts is reflected to the eye of the observer in inverted posiiio?i, sothat the right vocal cord appears on the left side, just as the rightarm appears on the left in a looking-glass. Experience will soonenable the observer to correct this falsity of representation, and hewill do this quite unconscious of any mental eflbrt (Fig. 17). Bymeans of this instrument the deep portion of the pharynx, thelarynx, the passage through the glottis, the mucous membrane ofthe trachea, are all capable of being seen. The epiglottis and pos-terior aspect of the base of the tongue, as well as the posterior as-pect of the pillars of the fauces, and the condition of the nares, are * Laryngoscopic examination of a patient (after Dr. Geokge Johnson). The illu-mination of the pharynx is effected by light cast into the patients mouth from amirror over the brow of the operator. Dr. Johnson has recently suggested that theoperator should also use a shade to shield his eyes
