• Using the fundamental equations of motion of a viscous fluid, the condition to be fulfilled for similar motions has been derived. This is the law bearing the name of Osborne Reynolds. The surface of a body moving in a fluid is covered with a sheet of vortices ("Grenzschttheorie") and on the stream line along which the pressure on this body is to be integrated (and, first of all, there the law of similitude should hold) this law of similitude is affected if there is a dissimilarity in the gradient of vorticity. If the dissimilar condition of surfaces accounts for this dissimilitude, some experimental results hitherto obtained can be explained. It is to be pointed out that the variation in surface condition is equivalent to the apparent change of Reynolds' number.
