We report the low-field ac susceptibility from 16 Hz to 2.8 MHz on the dilute spin-glass Ag:Mn in the vicinity of the glass temperature, TG. Within experimental error TG is frequency independent. We also report electron-spin-resonance measurements in the same samples at 1.6 and 9.1 GHz. The differences in the ESR data at two frequencies appear to be due to the different fields for resonance and not to the different measuring frequencies.
