A simple-minded perturbation calculation to order G (the Newtonian gravitational constant) of the two-graviton coupling to a pseudoscalar (P) or axial (A) current via a fermion loop gives an anomalous contribution which can be added to the Adler term in the form αAα = 2mP + e2ϵkλμvFFμv/16Π2 + ϵkλμvRkλϱσRμvϱσ/768Π2. The anomalous terms can be interpreted as arising from an infinite-mass regulating loop.
