Peroral endoscopy and laryngeal surgery . of the larynx, it would seem that the now generally usedterm lan^ngoscope is preferable.

Laboratory work has shown that there is,under normal conditions, a sharp line of limitation of oral sepsis at the INSTRUMRNTS. 17 orifice of the larynx. The first form of laryngoscope used by the authorwas modeled after the original Kirstein autoscope which had its trans-verse greater than its vertical diameter. A double handle was attachedto a simple oval tube with half its periphery cut away for the distal two-thirds of its length (Fig. 15). Then, after Killian created hronchoscopv,the author added a slide at the side for bronchoscopy. Pioth of these. Fig. 8. Kaliler panelectroscolie. The tulics used with this arc similar to thesliding tubes of Briinings. The rays of light from the lamp, h, are rcHccted by themirror, g, into the tulie, e. The endnscopists eye is placed at the notch in themirror, g. The mirror can be thrown out of the way for the introduction of in-struments hy pressure of the tluimli on the arm, c. laryngoscopes were used with the ordinar_\- head-mirror, and witli theWendell C. Phillips head-lamp worn between the eyes. As the authorfound the oval lumen less convenient than the round for working at theside instead of over the dorsum fif the tongue, as he fre(|ucntlv wishedto do. he abandoned the n\al lumen for the niund lumen with the slide 18 INSTRUMENTS.
