The investigation which is the subject of this paper was undertaken to test the conclusions recently drawn by Professor D. C. Miller from his repetition of the Michelson-Morley experiment. Professor Miller interprets his observations as indicating a motion of the sun through the ether with a velocity not less than 200 kilometers per second in a direction about right ascension 262 degrees, declination 65 degrees. He supposes that a contraction of the apparatus in the direction of motion occurs, which, however, departs from that given by the formula of Lorentz and Fitzgerald by an amount corresponding to a velocity of about 10 kilometers per second.
