    § 2. Ulcerations of the Larynx, Ulcerations of tlie larynx were, as already indicated, some- what less common than those of the trachea, rarely occurred where the latter were not present, and existed in the fourth part of my cases. In two instances only did I detect them, where the trachea was free from similar change. Their cha- racters were in many cases very dilferent from those of the tracheal ulceration ; rarely superficial, or looking as if made with a punch, they were commonly of a certain depth, more or less irregular in outline, and covered a space varying from about one to ten lines [2 to 20 millimeters] : their edges, varying in amount of hardness, were sometimes lardaceous; their colour grayish or whitish. The mucous membrane exhibited elsewhere the characters of perfect health. The point of junction of the chordse vocales (where they were sometimes superficial) was the most common seat of these ul- cerations ; next in order of frequency came the chordae vocales themselves, especially at their posterior aspect, the base of the arytenoid cartilages, the upper part of the larynx, and, lastly, the interior of the ventricles, where indeed I but once met with a small superficial ulceration. Sometimes one or more of the chordae vocales were totally destroyed and the base of the arytenoid cartilages laid bare. The cartilages themselves were, under these circumstances, per- fectly sound. § 3. Ulcerations of the Epiglottis. I found ulcerations of the epiglottis in eighteen subjects, or about the sixth part of my cases,—five times without coexist- ing ulceration of the larynx and trachea. This latter compli- cation existed in the other cases; in such manner that all the examples of ulceration, enumerated under the present heads were furnished by forty-four cases, about four tenths of those now submitted to analysis. Though sometimes superficial the ulcerations of the epiglot- tis were generally of a certain depth,—^yet in two cases only did they reach the fibro-cartilagc beneath. When superficial.
