The like is obfervable in catarrhs, where a certain degree of inflammation ex- cites a free difcharge from the nofe, fauces, and bronchia; • whilft an increafed inflammation of the internal furface of thefe parts not only fupprefTes fecretion there, but is fol- lowed by a fenfe of fullnefs in one or both noftrils, dyfp.](https://iiif.wellcomecollection.org/image/b21133852_0030.jp2/full/800%2C/0/default.jpg)
