Detailed measurements of the specific heat jump $delta$C at the superconducting transition temperature T/sub c/ as a function of T/sub c/ are reported for several (La,Th)Ce systems. The measurements document the continuous demagnetization of the Ce impurity ions which proceeds with increasing Th concentration, and provide a critical test of a theory recently developed by Mueller--Hartmann and Zittartz for the superconducting behavior of matrix-- impurity systems which simultaneously exhibit both superconductivity and the Kondo effect.
