We reexamine the integral equations for the Cooper instability of the Hubbard model in the Gutzwiller boson formation. We solve numerically for the frequency dependence of the fermion-fermion vertex and, following conventional Eliashberg techniques, obtain {ital T}{sub {ital c}} versus pressure for {sup 3}He. The calculated results are within a factor of 2 of the experimental ones.
