Query: Hadronic Decays of J/psi(1^{3}S_{1}) and psi'(2^{3}S_{1}) Through
  Vitrual Photons   The latest data for J/psi and psi' leptonic decays, and the latest
measurement of the R-parameter are used to show that the present summary values
of the branching ratios of the virtual photon mediated hadronic decays of both
J/psi and psi' are overestimated. The current best results are B(J/psi ->
gamma^{*} -> h) = (13.3 +- 0.3)%, and B(psi' -> gamma^{*} -> h) = (1.65 +-
0.10)%.
