WIRELESS FOR DEAF PEOPLE.

MEDICAL EXHIBITION! WONDERS. HEART BEATS REGULATED BY ELECTRICITY. The use of wireless telephony for the relief pf deafness was demonstrated at the Medical Exhibition at Central Hall, Westminister, S.W.„ to aural surgeons. In people hard of hearing one ear) is usually worse than the other, and the whole of the work falling on the better ear strains it and causes further deterioration. In the work of "rei-educaiting” the ear in 'which the deafness- is more pronounced aurists have' depended, hitherto on an instrument making simple noises, but wireless telephony aas now been enlisted in the service ef the specialist. The head-piece of

an ordinary receiving set is connected to the dull ear, and in this way it is stimulated by the human voice without any strain being imposed on ; the other ear. Electric Waves for Hearts. Doctors were much interested in r the Static Wave Device pf Messrs T. Clarke .and Son, Manylebpne Lane, W., for regularising the beat of the heart if it should be cithelr too fast 01; too slow. The patient sits on an insulat- ’ ed chair connected with an electrical ' machine from .which a current passes ! into his 1 .body. There is a revolving ball which can ' be tuned to any number of revolu- ' tions a minute, and every .time this passes a fixed ball the electiricity is , discharged from the body, relaxing all the muscles. If the heart should beat naturally at 74' per minute but is beating at 80, the ball is timed to ’ make 74 revolutions, and thus the heart is brought back to its normal : rhythm.
