![DISEASES OF THE RESPIRATORY ORGANS. SECTION I. AFFECTIONS OF THE LARYNX. CHAPTER I. HYPERJEMIA AND CATARRH OF THE MUCOUS MEMBRANE OP THE LARYNX. Etiology.—[Whenever there is hyperaemia of a mucous mem- brane, active or passive, the condition known as catarrh is also more or less distinctly observable. The morbid processes characterizing this condition are veiy manifold, now one, now another of then predominating, thus imparting to catarrh a great diversity of form. Here a flow of mucus may prevail, due to changes in the epithelial and glandular cells ; there the main feature may be a liberation of crude round cells, the so-called pus-corpuscles or mucus-corpuscles, as in purulent catarrh or hlenorrhoea. In cases even yet more intense there may be an excessive serous exudation, which imparts a watery character to the discharge, or else causes an infiltration of serum within the mucous membrane itself—oedema—instead of the usual more moderate succulence.] Now we find that hability to catarrh varies greatly among persons exposed to the same exciting cause; and that in one this mucous surface, in another that, is always the favorite point of attack. Special predis- position, in some cases, seems to coexist with a thin epidermis and a strong tendency to perspire; for those who sweat readily are the more apt to be suddenly chilled by the rapid evaporation of their perspiration. Badly-nourished, cachectic persons too, who are less capable of resist- ing the action of hurtful agents, are, on the whole, more prone to ca- tarrh than full-blooded and robust individuals. In other instances there is no clew whatever to the,cause of an intense predisposition to this afi^ection. Elfeminate habits seem to aggravate it. At all events, we see that country people, shepherds, and others, who live continu- ally exposed to changes of temperature and to stress of weather, are less frequently thus aifected than persons of sedentary habits, and those who are but rarely subjected to such exposure.](https://iiif.wellcomecollection.org/image/b20418814_001_0021.jp2/full/800%2C/0/default.jpg)
