Let (Mi,Ai)i(M_i,A_i)_i be pairs consisting of a complete Riemannian manifold MiM_i and a nonempty closed subset AiA_i. Assume that the sequence (Mi,Ai)i(M_i,A_i)_i converges in the Lipschitz topology to the pair (M,A)(M,A). We show that there is a number c0c\geq 0 which is determined by spectral properties of the ends of MiAiM_i-A_i and such that the intersections with [0,c)[0,c) of the spectra of MiM_i converge to the intersection with [0,c)[0,c) of the spectrum of MM. 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.
