We use the reaction e-italic/sup +/e/sup -/..-->..hadrons, in the Mark J detector at the DESY electron-positron collider PETRA, to determine the hadronic cross section up to 46.78 GeV. The production of a top quark with a charge equal to (2/3) is excluded up to 46.6 GeV with 95% C.L. The observed rise in the cross section at higher energies is consistent with the electroweak prediction for a Z-italic/sup 0/ mass of 93 GeV. We describe some unusual muon inclusive events.
