Strange to say that after he had had a favorable reply he gradually recovered his hearing! In the same paper there is an instance of a case of deafness due to the sudden cessation of perspiration, and an instance of tinnitus due to the excessive use of tobacco; Roosa also mentions a case of deafness due to excessive mental employment.
Perforation of the Tympanum .-- Kealy relates an instance in which a pin was introduced into the left ear to relieve an intolerable itching.

It perforated the tympanum, and before the expiration of twenty-four hours was coughed up from the throat with a small quantity of blood.

The pin was bent at an angle of about 120 degrees.

Another similar case was that of a girl of twenty-two who, while pricking her ear with a hair-pin, was jerked or struck on the arm by a child, and the pin forced into the ear; great pain and deafness followed, together with the loss of taste on the same side of the tongue; after treatment both of the disturbed senses were restored.

A man of twenty was pricked in the ear by a needle entering the meatus.
