High-speed photometry of the hydrogen-deficient star BD +10°2179 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.
