    The chief result implies that an n-manifold S embedded in the interior of an (n + 1)-manifold M as a closed, separating subset is locally flatly embedded if the embedding is well behaved in a locally peripheral sense and if S has arbitrarily close neighborhoods Q such that the fundamental groups of appropriate components of$Q \backslash S$admit a uniform finite upper bound on the number of generators.
