We calculate nonlinear Knight shift {ital K} vs susceptibility {chi} anomalies for Ce ions possessing local moments in metals. The ions are modeled with the Anderson Hamiltonian and studied within the noncrossing approximation. The {ital K} vs {chi} nonlinearity diminishes with decreasing Kondo temperature {ital T}{sub 0} and nuclear-spin--local-moment separation. Treating the Ce ions as an incoherent array in CeSn{sub 3}, we find excellent agreement with the observed Sn {ital K}({ital T}) data.
