Zimmermann's normal-product algorithm is developed for the renormalizable gamma /sub 5/ interaction of meson- nucleon dynamics. With the help of Zimmermann's algebraic identities Wilson's shortdistance expansion and the Zimmermann identity are verified in perturbation theory for a fermion-- fermion operator product. The power of this method is demonstrated in clarifying problems which seemed to appear in earlier, less rigorous, treatments of a generalized Ward-identity for the axial vector in such a field theory.
