We measure the temperature dependence of the nonlinear susceptibility 
, which reflects the fluctuation of quadrupolar moments in, PrLaPb which a non-Kramers doublet in the crystal-electric-field ground state to provide evidence of the quadrupolar Kondo effect. Non-Fermi liquid behavior of with a - ln 
dependence is detected in the [100] and [110] directions below 
2.5 K, suggesting the screening of quadrupolar moments. In contrast, in the [111] direction becomes constant below 3 K. The observed features indicate that a low-lying doublet plays a crucial role in the anomalous properties of Pr
