This paper reports the detection of repetitive pulses of hard X-rays and gamma rays in data obtained in mid-1967 from the Crab Nebula. The pulses are believed to originate from NP0532 since the observed repetition period is what would be expected on the basis of an extrapolation of recent optical data obtained for NP0532 back to the time of the observation.
