The elusive variability of BD + 10.2179 degHigh-speed photometry of the hydrogen-deficient star BD + 10.2179 deg has been obtained in order to ascertain if it is presently pulsationally unstable with the previously published period of 0.162 to 0.164 d. During an observing run of 0.21 d no pulsations were observed above the noise limit of 0.002 mag. Either the previously published period is not real or the star is no longer pulsating.
