Measurements in a turbulent wake indicate that, in the inertial range, the power law exponents inferred from the transverse velocity and temperature increments are nearly equal and significantly smaller than the exponents of the longitudinal velocity increment. The relative magnitudes of the exponents for moments up to the eighth order have been determined using the extended self-similarity method.
