Still in its infancy, the art of sound reproduction is being expanded on all sides, largely with special reference to the gramophone. In that wonderful and popular devel-lopment of the principle, attention is now being concentrated on the business of reproducing, the recorded vibration. In this the sound-box is the all-important factor. It is, to borrow a term from another and equally wonderful discovery—wireless telegraphy—the coherer. Through it the sound waves impressed on the dise are reasserted and made audible. The vibrations are communicated by the needle to the responsive surface of the sound-box, and from there conveyed to the air, either with or without the aid of a horn or other means of reinforcing the resonance. An ingenious mind, that of Mr. W. E. Clifton, who has already devised many improvements to the gramophone, has now evolved a new kind of sound-box. The shape remains the same adaptable form in general use, but the construction is such as to give increased fidelity to' the reproduced tone, which is made larger and rounder. In conjunction with it a new shape of horn has been devised by the same hand. Tt augments the tone to a very marked degree. and, while of comparatively small dimensions, has the effect of a more extensive arrangement.
