The low-frequency (5-i00 kHz) dielectric constant e has been measured in the temperature range 7 Γ 10 -s < t = (T-Tc)/ T c < 8 Γ 10 -2. Near T c an exponent ~0.11 characterizes the power law behaviour of de/dt consistent with the theoretically predicted t -a singularity. However, over the full range
