Let be pairs consisting of a complete Riemannian manifold and a nonempty closed subset . Assume that the sequence converges in the Lipschitz topology to the pair . We show that there is a number which is determined by spectral properties of the ends of and such that the intersections with of the spectra of converge to the intersection with of the spectrum of . This is used to construct manifolds with nontrivial essential spectrum and arbitrarily high multiplicities for an arbitrarily large number of eigenvalues below the essential spectrum.
