We have located 3886 neutrino interactions in the fiducial volume of a hybrid emulsion spectrometer installed in the Fermilab wide-band neutrino beam. A search for tau/sup -/ decays yielded no candidate, resulting in an upper limit of 0.002 (0.073) for direct coupling of ..nu../sub ..mu../ (..nu../sub e/) to tau/sup -/. The ..nu../sub ..mu../ (..nu../sub e/) to ..nu../sub tau/ limits to mass differences and mixing angles (..cap alpha..) between the neutrinos are at maximum mixing ..delta..M/sup 2/<0.9 (9.0) ev/sup 2/, and at maximum sensitivity sin/sup 2/(2..cap alpha..)<0.004 (0.12). The direct-coupling limits are also used to show that most tau/sup -/ decays must contain a neutral lepton other than ..nu../sub ..mu../ or ..nu../sub e/.
