Previous calculations of the effect of a critical point on the thermopower of metallic ferromagnets are extended to include inelastic scattering processes. Denoting the (temperature-dependent) localized spin-spin correlation function by gk(), where k is the momentum transfer, and the frequency transfer, the thermopower is shown to be proportional to frequency integrals of g2kF() and frequency and wave-vector integrals of kgk(). Only if the spin-spin correlation function exhibits critical "slowing down" for all frequencies at all k's (an unlikely prospect) does our result reduce to those found previously.
