Abstract

THE following cablegram has been received from Prof. W. B. Cartmel, of the University of Montreal: A Simple Means of Checking the Michelson-Morley Experiment’. In a letter under the above title which appeared in NATURE of January 16, I reported experiments in which I found a large fringe-shift with a small interferometer having one arm inclined at an angle of 45 ° and the other arm level. Unfortunately, on continuing my experiments with improved apparatus, this fringe-shift disappeared altogether, so that we get the same result with one arm inclined and one arm level as we do with both arms level, the effect previously reported being apparently spurious.”
