Abstract
The difference measured in the rates of propagation of shear ultrasonic wavesv zx andv zx in an ADP crystal is one of the bases of the Laval-Raman theory of the elastic properties of crystals. In the present paper an attempt is made to obtain by calculation a similar difference in rates within the old Voigt theory by using the more perfect methods of computation of Lawson and Paillouxe. The calculations, together with an estimate of the influence of second-order effects, however, indicate that the measured differences in rates cannot be explained even in this way by means of Voigt's theory.
