A general method for the study of elastic‐ware propagation in anisotropic media is applied to the case of trigonal symmetry. A section of velocity surface for calcite is given. For elastic waves propagated in anisotropic media, the energy flux deviates from the direction of the wave normal. This prediction has been verified in the case of calcite. An optical method is used to observe the deviation of the quasilongitudinal ray from the wave normal.
