The Audiphone.—In his address on the mechanical genius of the Americans, last Saturday, Mr. James gamuelson showed the model of a new instrument called the Audi-phone, which is destined to afford the means of hearing to deaf persons. It consists of a large thin plate of metal, which is held between the teeth, and acts as a sound board, transmitting sounds to the brain in cases where the ear is imperfect, and unable to perform its functions. Mr. Sam-uelson has now received one of the Audiphones from America, and tested it on Monday upon a number of gentlemen who are more or less hard of hearing, with very excellent results. After giving it a further trial, and fully satisfying himself of its efficiency, he will take means to enable all persons who are afflicted with deafness to witness its operation.

Later.—(Same paper, December 2, 1879.) On Saturday afternoon last, there was held, in the Lecture Hall of the Free Library, a meeting in connection with the Liverpool Science and Art Classes, when the chairman of these classes, Mr. James Samuelson, exhibited an instrument designed as an aid to the deaf—the Audiphone—which he met with during his late visit to America. Mr. Councillor J. A. Picton presided, and there was a crowded audience, there being present several medical gentlemen and others interested in matters pertaining to deafness. Mr. Samuelson first gave a brief description of the structure of the several parts of the ear, and explained how, by the use of the Au- page 39 diphone, sonorous vibrations are gathered up and transmitted through the bones of the face and the skull to the auditory nerve. He next asked several gentlemen on the platform, including Dr. Nevins, to test the instrument, and they all pronounced it a great assistance to hearing. He then tested it on two pupils from the Deaf and Dumb Institution with satisfactory results. Afterwards about a score of persons of different ages and conditions and degrees of deafness came forward from among the audience, and made a trial of the instrument, and in nearly every case it was clearly shown that such sounds as those of the voice, of a bell, a whistle, or a musical instrument, could be heard by the aid of the Audiphone, where without it they were inaudible. The general result appeared to be that, provided the auditory nerve itself was in a healthy condition, the Audiphone was of great assistance to deaf persons. Mr. Samuelson mentioned that the inventor was a Mr. Rhodes, of Chicago, and, in answer to many inquiries from the audience, stated that the Audiphone was now being manufactured by Messrs. Rhodes & McClure, of Methodist Church Block, Chicago, and sold at a price of about ten dollars. The meeting, which was of a most interesting character throughout, concluded with a very hearty vote of thanks to Mr. Samuelson for calling attention to so useful an invention.
