Single crystals of praseodymium ethyl sulfate were cooled below 1 deg K by adiabatic demagnetization and the susceptibility expressed in terms of the magnetic temperature T, was measured as a function of T, using cerium magnesium nitrate as a thermometer. The specific heat was measured by electrically heating the sample. A systematic departure of the unsceptibility from Curie's law and an anomaly in the specific heat were found. The results were interpreted and confirmed the existence of a variable splitting of the ground doublet, as predicted from paramagnetic-resonance experiments, with a root-mean-square value of DELTA /sub o/ = (0.53 plus or minus 0.04) deg K which is much larger than the one in the diluted salt.
