Summary. The effect of initial stress on the velocities of plane elastic waves is considered and corrections to the first order in terms of initial stress for P ‐and S ‐waves are obtained. The results are compared with those of Dahlen, who found that to the first order the initial stress had no effect on P ‐wave velocities: this conclusion is shown to be correct only when the unstressed material is isotropic.
