==Abstract==

An ultrasonic range finder was mounted on a horizontally rotatable rail at fixed distance, s, to a reflector on the top of a car. The change of the distance reading, s, served to determine the two-way velocity of sound as a function of [car] velocity and direction. Result: the out- and back velocity c<sub>2</sub> was isotropic as in the optical case of the Michelson-Morley experiment. Within the experimental error it was found to vary as  c<sub>2</sub> = (c<sup>2</sup> - v<sup>2</sup>) / c.
