POULSEN'S ETHEREAL ELECTRICITY.

Before an audience of some scientific men, Mr "Valdemaar Poulsen recently dememstnated his new system of ethereal electricity, as Sir William Pneeoe, the chairman, described it. Sir William said that the lecturer's discovery seconded, the death-knell of tihe old "spark 1 ' electricity. and Mr Poulsen, in his paper, explained that his form of electricity -was capable of no fewer than a million vibrations per second, thus giving a practically continuous wave of energy. The "spark" form of electricity might be likened to a continuously vibrating tuning fork A set of six electric incandescent lamps were lighted "wirelessly" by its energy, a lamp was lit through Mr PooJson's body, copper wire was melted in mid-air, and a swinging copper wire fixed to the top of an induction coil in the darkened hall seemed like a waving scimitar of violet flame when the ethereal energy was ap plied to *t. In addition to it* advantages in wireless telegraphy (which include perfect "tuning" and the impossibility of tapping), the inventor expressed himself confident that it would be found to solve the problem of a wireless telephone.
