Abstract Local commutativity of different fields is shown to be a transitive property of fields. A criterion is derived which decides whether two local fields are interpolating fields to the same S-Matrix or not. It is shown that there exists more than one interpolating field to a given causal S-Matrix. (auth) l6405 The effects of the scalar and vector potentials in quantum mechanics which were pointed out recently by Aharonov and Bohm, are discussed from the point of view of the consistency of the quantum-mechanical description of interference experiments. A well-known requirement for this consistency is that if any measuring device is introduced that can be used to determine which path the particle has taken, it must have the effect of eliminating the interference phenomenon. Two conceptual experiments are discussed, corresponding to the two phase effects noted by Aharonov and Bohm. In each case it is found that the phase effect is of just the magnitude required to destroy the interference pattern when the circumstances are such that no pattern should be observed. (auth)
