Abstract
A previous finite-size study for the chiral phase transition of two-flavor QCD is extended to a smaller quark mass of ${m}_{q}=0.0125$ in lattice units. The characteristics of the system for lattice sizes (${6}^{3}$ - ${12}^{3}$) \ifmmode\times\else\texttimes\fi{} 4 are found to be quite similar to those for ${m}_{q}=0.0025$. The increase of susceptibilities over this range of the spatial size is still too mild to discriminate among the order of the transition also at this small quark mass.
