THE DISCOVERY OF X RAYS. EARLY in January the world at large was startled by the announcement of a discovery which, so far as we can yet tell, seems destined to prove an epoch-making incident in the development of physical science-the discovery of a hitherto unknown form of radiant energy, possessing a marvellous power of penetrating bodies opaque to ordinary light, and actinic enough to produce a shadow picture upon a sensitized plate. No one has yet secured sufficient data to be able to estimate fully either the theoretical significance or the practical utility of the discovery. None of the innumerable instances in which, both in Europe and in America, the original experiments of the discoverer have been repeated, and his observations confirmed, has yet served to throw absolutely conclusive light upon the nature of the new rays; nor have any afforded more than a mere hint of the bearing of the new phenomena upon accepted scientific hypotheses. What is already known, however, has brought scientists face to face with the possibility that their long-established theories regarding cosmic questions of the utmost magnitude-radiant energy, the luminiferous ether, gravitation, the constitution and forces of matter-may ere long have to undergo great modification. But whatever may be the theoretical import of the discovery, its practical value is already assured; and the benefits which will accrue from its application to the uses, especially of surgery and of some of the technical arts, can hardly be overestimated. The latter years of this century have formed a period of unprecedented scientific activity. The developments of electrical science under Edison, Tesla, Bell, and otherswhich have made the present an age of realized impossibilities are familiar to every one.
