Temperature-dependent inelastic-neutron-scattering measurements were performed on a single crystal of Ce${\mathrm{Pd}}_3$ over the energy range $-10<\hslash \omega <80\mathrm{}$ meV. The spectral response cannot be described by a single Lorentzian line as has been used for previous measurements on polycrystalline samples. The two energy scales which emerge from the data analysis correspond to those found in bulk measurements.
