We measure the temperature dependence of the nonlinear susceptibility ${chi}_3$ in Pr $_{0.05}$ La $_{0.95}$ Pb. ${chi}_3$ reflects the fluctuation of the quadrupolar moments. Non-Fermi liquid behavior of ${chi}_3$ with -dependence is detected below 2.5 K, suggesting that the screening of the quadrupolar moments is responsible for the anomalous behavior at low temperatures. These results provide a direct evidence for the crucial role of the quadrupolar moments in Pr $_{0.05}$ La $_{0.95}$ Pb.
