DEAFNESS.—The ORGANIC VIBRATOR, an extraordinarily powerful, small, newly-invented instrument, for deafness, entirely different from all others, to surpass anything of the kind that has been, or probably ever can be, produced. Being of the same color as the skin, it is not perceptible. It enables deaf persons to hear distinctly at church and at public assembles. The unpleasant sensation of singing noises is the ears is entirely removed; and it affords all the assistance that could possibly be desired.—39, Albemarle-street, Piccadilly. Observe, opposite the York Hotel.
