Abstract
Wave-length Measurements in the Series of Some High Frequency Spectra: a New Vacuum X-ray Spectrograph.—The paper contains a description of an X-ray spectograph designed to be used in the same chamber containing the source of X-rays, also a description of the vacuum chamber, the method of sealing, and details of manipulation of the apparatus.
A method is described of determining the position of the photographic plate upon which the lines are photographed.
Experimental data. Some measurements are made of lines in the series of bismuth, lead, thallium, mercury, gold, and platinum.
