[en] We consider a simple model of mesons as Coulombic bound states of quark-antiquark pairs confined in a box. A fit to the meson spectra and decay rates suggests that m/subu/=m/subd/approx. =0.3 GeV, m/subs/approx. =0.4 GeV, and m/subc/approx. =1.4 GeV. We also predict new meson systematics and metastable charmed baryons
