Before describing the various instruments in detail, I may ob-serve that whilst most Continental practitioners, as a rule, use laryngealinstruments curved like a catheter, from the first I employed those of amore angular form, and this type is universally used in England, andpretty generally in America. In a catheter the two extremities are atright angles to each other; but the angle is reduced to a minimum by alarge curve or sweep. This curve, though well adapted for the urethra,is much less suitable for the larynx; and if, on the other hand, the rightangle, slightly smoothed down, is left, the instrument in passing into thelarynx is kept free of the epiglottis. My meaning will be at once clear. Fig. 26.—Laryngeal Probes. on reference to Fig. 44. It will be seen that both the catheter-curvedinstrument (indicated by dotted lines), and ray rectangular instrumentreach the same spot; but whilst the former touches, and even pressesagainst the epiglottis, the latter avoids it. Hence the superiority of therectangular instrument. Probes.—It occasionally happens that it is desirable to introduce soundswithin the larynx. By means of such instruments the origin and densityof a growth may sometimes be ascertained, when with the unaidedlaryngeal mirror the information cannot be obtained. In cases of ulcera-
