The transport properties of dense binary fluid mixtures with one tracer component are discussed in the context of the revised Enskog theory (RET). Except for the mutual and thermal diffusion coefficients, the transport coefficients are those of the excess component alone. The kinetic diffusion coefficient is given exactly by its low density (Boltzmann) value divided by the magnitude of the radial distribution function at contact. The values of the mutual and thermal diffusion coefficients can be estimated to within 1% for all mass ratios ..mu... A comparison with earlier work on the limiting cases of the Rayleigh ( ..mu.. = infinity) and Lorentz ( ..mu.. = 0) gases is made.
