MAGNIFYING THE VOICE.

At the circus, in the presence of a select gathering of local notabilities, Colonel Gouraud, MT. Edison's well known coadjutor. showed for the first time in public a new sound transmitter, to which he has given the name of the Gouraudphone. Colonel Gouraud mod estly attributes the entire merit of the invention to a young American, MT. Horace Leonard ShoTt, who has 1t great expense, perfected the apparatus; the experimental stage is over and the public exhibition of it's power has be- come possible. Perhaps, mercifully for the audience, the occurrence of some damage in transit to certain parts of the instrument prevented complete demonstration of it's capabilities, for when fully equipped it transmits the human voice many times magnified in volume over enormous distance, several tens Of kilometers," according to Col onel Gouraud. It makes itself heard equally we'll in fog, and will also carry against very strong wind. Its value in many ways, if these promises are realized, and especially in connection with vessels at sea or in distress, can easily be imagined, and it's usefulness is increased by the fact that no receiver is required at what may be termed the other end to capture the sound or to make it intelligible.
 Almost all that was visible this af- ternoon to the observer was a gigantic graphophone funnel, and the colonel refrained from giving details of the construction of his apparatus, as he is reserving them for the British associa- tiOn, before which he will shortly read a paper on the invention. Later-that is to say. at about the end of Septem- ber-he will fix his machine on the up permcst platform of the Eiffel Tower, and from there will discourse through it without raising his voice, but his words will be heard all over Paris, even to the Notifications, and beyond.
 Colonel Gouraud made a little intro ductory speech in French, a language he speaks with remarkable facility, in spite of the fact that his whole life has been spent out of France, and in the course of it he explained that he had determined to give publicity in this country first of all for sentimental req sons, involving an interesting bit of
 
 States. the colonels father. a French man, died when he was only five years old, and since then he had until recent ly lost all trace of his French relatives. Not long since he discovered them and was received by them with open arms. His choice of French soil on which to disclose to the public his invention is kind of commemoration of his re- union with his relatives on the paternal side.
 His speech spoken in a phonograph in low tone, was repeated by the Gouraudphone with striking effect His voice quite filled the large circus Other examples of the power of the instru- ment followed; military trumpet calls rang sOnorously through the place, a cornet solo charmed the audience, a song sung into the phonograph by a French gentleman present was repro duced with twentyfold strength. It should be added that the phonOgraph was used as an intermediary solely be- cause the damage to portions of the machine prevented it's being worked as it would be under normal conditions Various other interesting demonstra- tions of the excellence of the new sound transmitter followed. and very cor dial vote Of thanks to Colonel Gouraud brought the proceedings to a close Boulogne Dispatch in the London News.
