    brana tympani is so obliquely situated, that an aper- ture in it allows of the ready entrance of fluid, but the escape is retarded by the anatomical conformatiorm of the part. Under these circumstances, the discharge is sometimes suddenly checked, and inflammation is set up, which extends rapidly to the brain, and seldom fails to destroy the patient, as this form of disease is invariably less amenable to treatment than even ordinary inflam- mation of that organ. If this result does not occur, the irritant injection, by remaining in the tympanum, greatly increases the danger of caries of the bones of the ear; an occurrence which sometimes leads to a fatal termination. The proper treatment of Otorrhcea, both mucous and purulent, after it has been proved to be eaternal, is, without losing sight of the general health, to exhibit injections at first but very feebly astringent, which may be gradaally increased in strength, until the discharge decreases and disappears. When otorrhcea becomes of long continuance, either from neglect or improper treat- ment, it is seldom that a similar lesion does not exist on the internal surface of the membrana tympani: in such eases, treatment by the external meatus alone will prove inefficient to restore the lost hearing. II. DEAFNESS FROM DISEASE OF THE CAVITY OF THE TYMPANUM, AND OF THE EUSTACHIAN TUBE. Discharges from the tympanic cavity, or internal otorrhcea, is a much more serious disease than the one we have been considering. It is usually the result of acute inflammation occurring in the ear, and is com- monly attended by perforation of the membrana tympani, and frequently by closure of the Eustachian tube; as a
