  As a follow-up on our earlier paper we calculate the $\chi^{2}$ of various
$N\!N$ potential models with respect to the $np$ scattering data. We find that
only the most recent potential models give a reasonably good description of
these data. Almost none of the potentials is truly an $N\!N$ potential in the
sense that it gives a good description of both $pp$ and $np$ scattering
simultaneously.
