The scattering of unpolarized Fermions and scalar mesons by single graviton exchange is considered by means of a Feynman graph type perturbation theory scheme. In the limit of scattering of the Fermions by very heavy mesons, one obtains the cross section for Fermions scattering in a Schwarzschild metric. The result obtained conflicts with an earlier result of Mitskevich. In the limit of scattering of massless Fermions (neutrinos) with massless scalar mesons it is seen, using Weinberg's treatment of soft graviton Bremsstrahlung, that the cosmological red shift of light cannot be explained by interactions of the light with intergalactic neutrinos.
