Abstract
In view of recent theoretical investigations by Epstein which show that the sensitivity of this experiment is less than had been supposed and thus render inconclusive the previous performance of the experiment by the author, the experiment has been repeated once more with still greater sensitivity. The present apparatus should detect a motion in the ether of as low as 3 km/sec. and no such motion is found.
