While objections have been raised to all the proof of Maxwell's distribution law there is probably little question it represents approximately the statistical distribution of velocities among the molecules of a gas. It is remarkable, however, that a direct experimental verification had never been made until Stern and Gerlach showed that the law was substantially followed when silver atoms were evaporated from a silver wire. A somewhat closer verification is being attempted by a similar method using as the gas cadmium vapor at low pressure. There are several applications of such a "velocity filter" to problems of kinetic theory.
