Von Philipp Bozzini, der Medizin und Chirurgie Doctor, Weimar, 1807. THE LARYNGOSCOPE AND ITS ACCESSORY APPARATUS. 159 •on the subject. Bozzinis invention consisted of two essential parts:First, a kind of lantern; and, secondly, a number of hollow metal tubes(specula) for introducing into the various canals of the body. The lan-tern was a vase-shaped apparatus made of tin, in the centre of which small wax candle. In the side of the lantern there were two roundholes, a larger and a smaller one, opposite each other. To the smaller onean eye-piece was fixed, to the larger the speculum was fitted. The flameof the candle was situated just below the level of these two mouth of the speculum—a tube of polished tin or sil-ver—was always of the samesize; but the diameter of thetube beyond its orifice variedaccording to the canal intowrhich it had to be intro-duced. The apparatus wasabout thirteen inches high,two inches from before back-. ward, and rather more than Fig. 11.—Bozzinis Laryngeal Speculum {after Hufeland).In the drawing from which this is taken, the mirrors are direct-ed upward, as they would be when employed in rhinoscopy. three from side to side. In employing reflected light, Bozzini had the speculum divided by a verticalpartition, so that there were, in fact, two canals and two mirrors. Oneof these mirrors was intended to convey the light, the other to receivethe image. In the year 1825,1 M. Cagniard de Latour, the successor of Savart atthe French Academy of Sciences, and like him, an earnest investigatorof the physiology of the voice, made an unsuccessful endeavor to examinethe larynx during life. In the year 1827,2 Dr. Senn, of Geneva, had a little mirror con-structed for introduction to the back of the pharynx; with it he tried tosee the upper part of the larynx—the glottis; bu
