The measurements of hadron and lepton{pair production cross sections and leptonic forward{backward asymmetries performed with the L3 detector at centre{of{mass energies between 130 GeV and 189 GeV are used to search for new physics phenom-ena such as: contact interactions, exchange of virtual leptoquarks, scalar quarks and scalar neutrinos, eects of TeV strings in models of quantum gravity with large extra dimensions and non{zero sizes of the fermions. No evidence for these phenomena is found and new limits on their parameters are set. Submitted to Phys. Lett.
