  Dilute Nd in simple cubic LaB$_6$ shows electrical resistance and specific
heat features at low temperature consistent with a Kondo scale of $T_K
\lesssim$ 0.3 K. Nd has a well localized {\it 4f}$^{3}$ {\it J} = 9/2 Hund's
Rule configuration which is not anticipated to be Kondo coupled to the
conduction electrons in LaB$_6$. We conjecture that the unexpected Kondo effect
arises via participation of {\it 4f} quadrupolar degrees of freedom of the Nd
crystal field ground state quartet.
