...lamp, by means of which excellent radiographs have been obtained. As the sides of the lamp permit cathode rays to pass through them, the fact that with it radiographs may be obtained contradicts the theory that a glass envelope plays an essential part in the generation of Rontgen rays...
...form of ray lamp has an interest aside from its construction, from the fact that experiments conducted with it appear to disprove the theory that a glass vacuum envelope plays a significant part in the generation of Rontgen rays. This theory, which was advanced by Dr. Rontgen himself, has been strongly supported by Poincare and provisionally accepted by other authorities. Yet Mr. Woodward has obtained excellent shadowgraphs from the radiations passing through the sides of the aluminum cone of his lamp. This supports another theory that has been offered, to the effect that Rontgen and cathode rays are independently generated...
Professor Trowbridge has consented to deliver a lecture before the Engineering Society on cathode rays and Rontgen's experiments, Wednesday, February 19, in the Jefferson Physical Laboratory. The lecture will be illustrated by experiments, and several interesting photographs will be shown by means of the lantern. It will be open to members of the University and their friends...
