The ring laser experiments, reported in 1964, by Macek, Schneider, and Salamon on the convection of light in moving media were incorrectly formulated. Optical path changes due to convection were overlooked. The Einstein addition theorem for parallel motion was inappropriately applied for non-parallel motion. The alleged agreement construed between wrong theory and experiment for moving quartz and air is inconclusive. The results presented for flowing CCl4, which did not agree with the incorrect formulation, contradict the correct Einstein and/or ether theory formulation. Excellent agreement is found instead for the experiment on CCl4and the correctly formulated prediction based on (etherless) classical kinematics.
