FIRST EDITION OF THE BRACE EXPERIMENT, "THE FIRST OPTICAL EXPERIMENT MEASURING THE RELATIVE MOTION OF EARTH AND THE LUMINIFEROUS AETHER WHICH WERE SUFFICIENTLY PRECISE TO DETECT MAGNITUDES OF SECOND ORDER TO V/C" (Wikipedia). Brace's results were negative, "which was of gret importance for the development of the Lor…entz transformation and consequently of the theory of relativity" (ibid). The American physicist and specialist in optics "examined the question [of] whether the Earth's motion may cause a body to become doubly refracting," something which as first sight might be expected (PRNAAS, 1904, 6, 809). Earlier in his career, Brace developed "extremely sensitive optical techniques" to one of the critical problems of the time (Dictionary of Scientific Biography, II, 382). "Two years earlier, Lord Rayleigh had proposed that the Lorentz-Fitzgerald contraction, if it existed, might produce an observable double refraction in a moving transparent medium. Rayleigh made experiments in which he failed to find the predicted effect, but his work was not quite accurate enough to be conclusive. Brace pointed this out and reconducted the investigation in his own laboratory, establishing beyond a doubt the absence of double refraction caused by movement of the refracting medium through the ether" (ibid).
