We review well known facts about charmed particles (i) that in the G.I.M. model the expected lifetime of a charmed particle is in the range (4 x 10/sup -13/--2 x /sup -12/) seconds (ii) that charm production cross-sections in the (5approx.20) ..mu..b range for 400 GeV proton-proton interactions are expected from quantum chromodynamics. We show that accumulating (and seemingly contradictoryexclamation) information regarding charmed particle lifetimes and cross-sections from counter, beam-dump and accelerator or cosmic-ray emulsion experiments converges on values consistent with these theoretical prejudices. The confirmation of perturbative Q.C.D. for calculating hadronic cross-sections of heavy particles is good news for the future hadron colliders discussed at this conferences: they might not only discover the weak intermediate bosons but also the t-quark and possibly the next flavor doublet.
