Temperature dependence of the ultrasonic attenuation a and the sound velocity Vs have been measured in a Lal.85Sro.15CuO4 single crystal under the magnetic field. A jump and a kink in Vs have been observed at the superconducting transition temperature Tc in the C33 and the CI! mode, respectively. A
