  A $d$-dimensional Ising model on a lattice torus is considered. As the size
$n$ of the lattice tends to infinity, a Poisson approximation is given for the
distribution of the number of copies in the lattice of any given local
configuration, provided the magnetic field $a=a(n)$ tends to $-\infty$ and the
pair potential $b$ remains fixed. Using the Stein-Chen method, a bound is given
for the total variation error in the ferromagnetic case.
