A Telephone Yon Can See Through.
Another wonderful invention comes from America. It is a photopLoue, the invention ot a Mr Fowler. "My invention has not yet been patented," said Mr Fowler," so you will understand how impossible it will be for me at this time to explain the details of the new telephone attachment. Another reason why secrecy is necessary is because my invention is not yet perfected. I have only just mastered the A B C of the photophone. as [ call if-, and while it i 3 true that it is now possible for a person to see the face of. the person at the other end of the wire reflected m the little receiving lens above the telephone mouthpiece, I am perfectly satisfied that that is only the beginning. When my invention is perfected it will be possible for two people, miles apart, to converse over the telephone and not only hear each other distinctly, bufc to see each other as well. " ido«f that is to be done is my secret. Since 1878 I have been trying to invent a photophone, and at last I have succeeded. The most amazing feature of my invention ia its simplicity. After puzzling over it for years and years I accidentally stumbled across the solution' a few. weeks ago, and at once constructed the experimental photophone service now m use m my home. It is a complete success, and now that it has | been demonstrated that reflections can be conveyed from one 'phone to another thirty or forty feet away, I am at work on a more extended photophone connection m which the reflections of two persons several miles apart will be visible over the 'phone to | each i.tber. These mirage rays which convey the reflection are operative for hundreds of miles. Space is of no more object than it is m the use of the telephone." The visible parts of the telephone, m Mr Fowler's house —that is, the receiving and transmitting portions with which the average person is familiar—are very similar to those m an ordinary 'phone. The only notideable addition is a camera-like attachment just like the front of a kodak with a magnifying lens m the centre. This lon 13 about three inches below the telephone mouthpiece so that a person talking into the 'phone can see his reflection m the lens. Above the lens there is a small incandescent light which is only used while the person at the 'phone is looking intently at the transmitting lens and getting his reflection into perfect focus. When he has done this he can turn out tbe light, taking care, though, not to sway or move from his position during tbe ensuing conversation. If he moves, the reflection m the transmitting lens becomes hazy or out of focus, and the person at the other end of the 'phone • notices it m the receiving lens into which he is gazing and on which the image of the person with whom he ib talking is thrown. How this image is conveyed from one 'phone to another ia a mystery. Still, as 1 Mr Fowler declares, tho secret is based on a problem of the simplest possible kind.
