We study a model of the weak interaction in which three W bosons interact with a triplet of fermion currents. The model is not renormalizable, but we make a canonical transformation of the Lagrangian that allows the most divergent terms in a perturbation series to be isolated, and their structure examined. Results recently obtained in lowest-order perturbation theory relating the leading divergence to the Cabibbo angle are explicitly shown to hold in all orders.
