<hidden TTP99-45  Relating the Quark Mass defined in the ``Regularization Invariant'' Scheme to the MS bar Mass at O(\alpha_s^3) > We report on the analytical calculation of the ${\cal O}(\alpha_s^3)$
 conversion factor between the $\overline{\mbox{MS}}$ quark mass and
 the one defined in the so-called ``Regularization Invariant'' scheme.
