  In this paper we demonstrate that the alternative form, derived by us in an
earlier paper, of the $n$-level densities for eigenvalues of matrices from the
classical compact group $USp(2N)$ is far better suited for comparison with
derivations of the $n$-level densities of zeros in the family of Dirichlet
$L$-functions associated with real quadratic characters than the traditional
determinantal random matrix formula. Previous authors have found ingenious
proofs that the leading order term of the $n$-level density of the zeros agrees
with the determinantal random matrix result under certain conditions, but here
we show that comparison is more straightforward if the more suitable form of
the random matrix result is used. For the support of the test function in
$[1,-1]$ and in $[-2,2]$ we compare with existing number theoretical results.
For support in $[-3,3]$ no rigorous number theoretical result is known for the
$n$-level densities, but we derive the densities here using random matrix
theory in the hope that this may make the path to a rigorous number theoretical
result clearer.
