    vowels and diphthongs in different tones, and by the simple rubbing of the pharyngeal organs and of the chords with a sound [Bruns, Rosshach), or even by the mere pressure from without upon the upper horns of the thyroid cartilage, the patient meanwhile making deep sonorous inspiratory movements {Ollivier), which, perhaps may be explained by the hypothesis that, in these long-standing palsies of the glottis-closers, a luxation outward of the cartilages takes place, which becomes reduced under the pressure above mentioned, so that afterward the electric current may have good effect (Ger- hardt). It has also been proposed to provoke reflex contractions of the muscles by insufflation of alum and other powders, and by the breathing of stimulating vapors. In a few exceptional cases good results have followed hypodermic injections of strychnine. All this treatment is usually tried when electricity (which usu- ally affords the happiest and sometimes the most astonishing results) has failed. In the latter treatment both the constant and the in- duced current may be employed. In some cases, especially in hys- terical aphonia, rapid and sure success is obtained by the percuta- neous method, wherein the electrodes are applied directly to the sides of the larynx. In more difficult cases direct faradization of the larynx {M. Mackenzie) is in place, the negative electrode being then set upon the neck without, while within a specially constructed intra-laryngeal electrode is applied to the chords or arytenoid carti- lages by help of the laryngoscope ; or, where but one muscle is af- fected, direct faradization is applied to it according to the precise instruction of Ziemssen. At first the effect of electrization is incom- plete and transient, and it is only after its patient and continued use that a lasting effect is obtained.] ADDITIONS TO THE REVISED EDITION OF 1880. SECTION I.—AFFECTIONS OP THE LARYNX, 1.—P. 3. During life, by aid of the laryngoscope, we can see that the ca- tarrh is sometimes diffused, sometimes circumscribed, and is often limited to a very small region. It may be recognized by its redness of variable intensity. In the more severe cases we find the epiglot- tis, the aryepiglottic folds, and the false chords thickened and of a deep-red hue, and perhaps so much swollen by (Edematous infiltra-
