Abstract
IF the pulsed radio source found near the Crab Nebula1 is a remnant of the supernova event of 1054, then the secular change in its period (assumed to be intrinsic to the source) reported by Richards2 can be used to estimate the age of typical longer period pulsars and hence the frequency with which pulsar-producing events occur in the galaxy.
