Results are reported from a proton beam-dump experiment performed at the 400 GeV CERN SPS using the Charm neutrino detector. Prompt electron-neutrinos and prompt muon-neutrinos, produced by decays of short-lived parents, have been observed. The ratio of the fluxes of (nu-bar/sub e/+..nu../sub e/) and of (nu-bar/sub ..mu../+..nu../sub ..mu../), measured by the rates of charged-current interactions with E/sub vis/>20 GeV, is 0.48 +- 0.12 (statistical) +- 0.10 (systematic). The ratio of nu-bar/sub ..mu../ and ..nu../sub ..mu../ fluxes is 1.3/sup +0.6//sub -0.5/. At low shower energies, 2
