The Geissler tube is the pioneer of many wonderful discoveries and speculations. The close study given to the discharge tube has been repaid by the manifold achievements of scientists following Roentgen’s investigations. Many theories have been offered to account for the nature of X-rays though none have satisfactorily explained the phenomena. With the discovery that they can be reflected and diffracted from crystals, increased interest has been shown in the attempt to reconcile certain theories with the observed facts. The classical electron theory and the quantum principles are now used though they appear to conflict with each other in certain phases such as scattering of rays and fluorescence. Neither of the theories account for all the observed phenomena. The study of Roentgen rays is a profitable field for learning the connection between these two points of view. One also acquires some knowledge of the atom and of crystal structure. Perhaps the study is of most interest in identifying X-rays with light and seeing the relationship established between the X-ray spectrum and the order of an element in the periodic table. While mention was made of these the principal object in this research was to summarize briefly the work of a few noted scientists in the spectroscopy of X-rays. Nothing has been said of X-ray diffraction apparatus. A complete description of such apparatus may be found in the General Electric Review of February 1926.
