The disorder is of a different nature, where there is a noise within the ears themselves: and this prevents them from receiving an external sound. This is slightest, when it proceeds from a gravedo; worse, when it is occasioned by a distemper or inveterate pains of the head; worst of all, when it is the harbinger of some violent disease, and particularly of an epilepsy. If it happens from a gravedo, the ear ought to be cleansed, and the patient hold in his breath, till some frothy moisture issue from it. If, from a distemper, or pain of the head, the same rules _as prescribed in a dulness of hearing_, must be practised with regard to exercise, friction, pouring on of cold water, and the use of gargarisms; no food but such as extenuates must be used; juice of radish, with oil of roses, or with the juice of the root of wild cucumber, must be infused into the ear, or castor with vinegar and laurel oil. Hellebore is also rubbed with vinegar, then incorporated with boiled honey, and being made into a collyrium, is introduced into the ear. If it has begun without these, and therefore gives reason to fear the approach of some terrible disease, castor ought to be infused into the ear with vinegar, or oil, either of iris or laurel; or together with the last, castor and the juice of bitter almonds; or myrrh and nitre with oil of roses and vinegar. But a proper diet is more serviceable in this case too. And the same rules are to be observed, which I prescribed above, even with greater exactness; besides which, the patient must refrain from wine, till the noise cease. But if, at the same time, there are both a noise and an inflammation, it is sufficient to inject laurel oil, or that, which is expressed from bitter almonds; with which, some mix either castor or myrrh.
