  In this paper the techniques of discretised QCD developed in physics/0109024
are are extended to a study of ground-state pseudo-scalar mesons involving
higher generation quarks. The correspondence with empirical data is good with
the exception of the charmed-bottom meson with the predicted value of 6.911GeV
varying considerably from the empirical value of 6.4 GeV although it is still
within two sigma and provides an avenue for further testing of the theory.
