  We present a calculation of the ratio of the charm quark mass to the strange
quark mass. Using the Brillouin improved Wilson action, we are able to
calculate this ratio in a single framework, using a relativistic fermionic
action throughout. The calculation is carried out on selected ensembles of two
flavor clover improved lattices produced by the QCDSF collaboration, allowing
an extrapolation to the continuum, to infinite volume and to the physical pion
mass.
