MEDICAL EXHIBITION WONDERS.

HEART BEATS REGULATED BY ELECTRICITY. The use of wireless telephony for the relief of deafness was demonstrated at the Medical Exhibition at Central Hall, /Westminster, 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 “re-educating” the ear in which the deafness is more pronounced aurists have depended hitherto on an instrument making simple noises, but wireless telephony has now been enlisted in the service of the specialist. The head-piece of an ordinary receiving set is connected tp the dull ear, and in this way it isi stimulated by the human voice without any strain being imposed on the other ear. ELECTRIC WAVES FOR HEARTS. Doctors were much interested in a Static Wave Device, for regularising the beat of the heart if it should be either too fast or too slow. The patient sits on an insulated chair connected with an electrical machine from which a current passes into his body. There is a revolving ball which can be turned to any number of revolutions a minute, and every time this passes a fixed ball the electricity is discharged from the body, relaxing all the muscles. If the heart should beat naturally at 74 per minute but is beating SO the ball is timed to make 74 revolutions, and thus the heart is brought back to its normal rhythm.
