    THROAT ON T11J-: OROAN OF IlKARINtJ. wore ciisos in which the disordered eoiidiiion of the throat had given rise to irritation within the tyinpaninn, which had taken on inllannnatory symptoms, and ended in snp- })iiration, tlie matter discliarging itself through the rup- tured mend)rane of the drum. Anotlier very troublesome comiilication of ear disease, tinnitus, often occurs as the setpiel of irritation in the throat and hv])ertrophy of these glands. Tinnitus rarely exists without a marked degree of deafness; but it does sometimes hajtpen when the tonsils are not of sullicient magnitude to occasion deafness, though loss of hearing generally follows when this distressing symptom has once established itself. Elsewhere* I have insisted on the paramount import- ance of a healthy state of the mucous membrane of the ear to perfect hearing. 1 have advanced the novel view, that by far the greatest number of deaf persons have lost their hearing by a diseased condition of this same mucous membrane. This I have substantiated by facts, and have ])ointed out the better methods of prevention and cure which must result from such an imj)roved knowledge of the pathology of the car. The modes in which external agencies can affect the lining membrane of the tympanal cavity are, in the first ])lace, through the external passage and the fibrous membrane of the drum, and in the second, through the Eustachian tubes entering to the ear from the throat and posterior narcs. Of the two tracks there can be no shadow^ of doubt that the latter is by far the most frequent. The external ineaius enjoys a conqiarative protection from cold on account of the i)i*esence of wax, and the structure of the membrana tympani forms a very efficient protection to the middle ear in this direction.
