Abstract
It is shown that doubts concerning the validity of previous proofs that anomalous averages cannot occur in three-dimensional systems of finite cross section or thickness are unfounded. The absence of anomalous averages in Bose systems of finite cross section is explicity demonstrated to illustrate the point.
