  We consider the contribution of magnetic impurities to the nuclear magnetic
susceptibility $\chi$ and to the specific heat $C$ of a metal. The impurity
contribution to the magnetic susceptibility has a $1/T^2$ behaviour, and the
impurity contribution to the specific heat has a $1/T$ behaviour, both in an
extended region of temperatures $T$. In the case of a dirty metal the RKKY
interaction of nuclear spins and impurity spins is suppressed for low
temperatures and the main contribution to $C$ and $\chi$ is given by their
dipole-dipole interaction.
