In this report numerical results concerning the longitudinal ion viscosities, heat conductivities and thermal diffusion ratios in magnetised D-He and H-C plasmas are presented within Grad's 21 moment approximation. The results are based on analytical formulae. Calculations taking full account of the finite mass ratio m(+)/m(z) between hydrogen (deuterium) and impurity ion mass are compared with those where m(+)/m(z) is very much less than 1. As expected, the largest discrepancies between exact and approximate results (with respect to the mass ratio) arise for D-He plasmas. The approximate formula for the impurity ion heat conductivity has to be extended to remove some hitherto existing deficiencies.
