The velocity equation for the surface ivavesof the Rayleigh type is derived in the caseof an idealized medium of uniform twodimensionalanisotropy: the elastic constantsare assumed to be everywhere the same buidifferent as far as vertical and horizontaldirections are concerned, and moreover thepossible inference of uniform initial stresses,(horizontal tensions or compressions) is included.There are then five independantelastic constants instead of four to be takenin account, in order to study the propagationof a tivo-dimensional surface-wave, the effectof a transverse initial stress being todestroy the symmetry of the cross elasticconstants
