  In a recent Letter, Kusenko and Segre proposed a new mechanism to explain the
observed proper motions of pulsars. Their mechanism was based on the asymmetric
neutrino emission induced by neutrino oscillations in the protoneutron star
magnetic field. In this note I point out that their estimate of the asymmetry
in the neutrino emission is incorrect. A proper calculation shows that their
mechanism at least requires a magnetic field of 10**16 G in order to produce
the observed average pulsar velocity.
