In the normal dense Kondo state of CeCuzSi., the nuclear magnetic relaxation rate1 / T. of "C u divided by T, 1 /T.Tis almost constant below 2.5 K with a slight increasenear the superconducting transition temperature. Together with the results of othernormal Kondo lattice compounds, it is concluded that the temperature dependence ofI / T.T at low temperatures does not scale to that of the specific heat divided by T,C(T)/ T in Kondo lattice compounds in contrast with the case of dilute Kondo im-purities. In the superconducting state, 1/7'.7'varies as T', suggesting the gap zerosalong lines, while the reported data of C.(T)/ T show no simple power lawdependence. It is claimed that this difference below T. may be correlated with thedifference between l /T.T and C( T) / T in the normal dense Kondo state.
