Medical men are interested in the new ray because it has been proved beyond question that all forms of bacteria die speedily under its effects. This has been so well estab. lished that we shall likely hear of exclusive experiments on medical lines, and the discoverer himself believes that for medicinal purposes it might prove invaluable provided its strength can be regulated so as to be harmless to the he puts it, however, his 0 far made on rabbits show that the cure would probably be much more serious than the disease. He has not yet tried the tube's rays on human Deings, nor yet found practical a} plication for them, but is confident that his tube opens limitless fields for electrical experiment and. research. During a semi-exhibition of the power of the ray, which was held ina darkened room, and with a current. of 30,000 volts applied to the tube, the tays were visible as a purple glow in front of a nickel foil "window," extending a foot or more from the end of the tube. All onlookers were immediately "struck with the fact that while the rays were visible the odour of ozone was noticeable, A exystal of calcite, Iceland spar, was placed in front of the "window, and immediately the rays were played upon it, it glowed as though it were red hot, and when the rays were shut off' the calcite continued to glow. It was then picked up and assed from hand to hand, so bri lantly red and giving to' the eye the appearance of being intensely bhat, that there was almost an instinetive desire to drop it. Yet it proved to be stone cold, and for hours afterwards its luminosity continued, gradually fading.
An experiment with mille showed that, when having been subjected to the ray, it became unpalatable and ill_ smelling.
