Query: On neutrino masses and leptonic mixing   Using recent data on neutrino oscillations, we argue that a hierarchical
solution for neutrino masses in a three-family context is possible, and that
the masses of the tau and mu neutrinos are very nearly determined within that
possibility. We also examine the predictions of a model that determines
neutrino and charged lepton mass matrices as well as its consistency with data.
