Abstract
BY means of an improved canal ray tube of Dempster type which gives sharp displaced lines, and with a diffraction grating of 15,000 lines to the inch, Dr. H. E. Ives has observed a displacement of hydrogen lines of approximately 0-05 A. towards the red, independent of the orientation of the apparatus. This positive effect confirms the Larmor and Lorentz theory of the relation between matter and the luminiferous ether, according to which a moving clock (in this case the hydrogen molecules emitting the light waves) has its rate decreased in the ratio ν = ν0 1- V2/c2.
