When disease or irritation of the larynx is present, these muscles are hable to close the opening of the tube suddenly, and keeping it closed to produce or threaten suffocation. The affections of the larynx may be classed under the heads of spasm, inflammation, ulceration, polypi. I. Simple spasm of the leivynx is met with in the fits of children attended with crowing inspiration, in hysteria, in hydrophobia. TI. Iriflammatioiis about the larynx present four varieties. a. Acute laryngitis, with effusion of croupy membrane or lymph on the mucous membrane, rapid prostration, suffo- cative seizures, death in two to four days. [z/. 45.] h. Erysipelatous inflammation of the mucous membrane of the epiglottis and lips of the glottis, with effusion of serum into the subjacent cellular membrane, producing oedematous narrowing of the opening, and spasm,—sometimes fatal in two or three hours. c. Inflammation of a similar character but with less oedema; not alarming till suppuration is established below the mucous membrane. In each of these cases, bronchotomy, or laryngotomy, are required to prevent immediate suffocation. d. Subacute inflammation of the mucous membrane attends the latter stages of three cases out of four of phthisis, ag- gravating the cough and dyspncea. III. Ulcers of the larynx are of frequent occurrence, and are often combined with phthisis. Alone they constitute phthisis laryngea: they generally commence upon the](https://iiif.wellcomecollection.org/image/b21066735_0549.jp2/full/800%2C/0/default.jpg)
