tative Colonel G. E. Gouraud, we have had an opportunity of testing one. A number of phonograms, taken in Edison's laboratory, were sent over with the instruments, and several of them were caused to deliver in our hearing the sounds which were
'sealed in crystal silence there.'
The first was a piece which had been played on the piano, quick time, and the fidelity and loudness with which it was delivered by the hearing tube was fairly astonishing, especially when one considered the frail and hair-like trace upon the wax which had excited it. There seemed to be something magical in the effect, which issued, as it were, from the machine itself. Then followed a cornet solo, concert piece of cornet, violin, and piano, and a very beautiful duet of cornet and piano. The tones and cadences were admirably rendered, and the ear could also faintly distinguish the noises of the laboratory. Speaking was represented by a phonogram containing a dialogue between Mr. Edison and Colonel Gouraud which had been imprinted some three weeks before in America. With this we could hear the inventor addressing his old friend, and telling him to correspond entirely with the phonograph. Colonel Gouraud answers that he will be delighted to do so, and be spared the trouble of writing; while Edison rejoins that he also will be glad to escape the pains of reading the gallant colonel's letters. The sally is greeted with a laugh, which is also faithfully rendered.
One day a workman in Edison's laboratory caught up a crying child and held it over the phonograph. Here is the phonogram it made, and here in England we can listen to its wailing, for the phonograph reproduces every kind of sound, high or low, whistling, coughing, sneezing, or groaning. It gives the accent,
