The differential cross-sections for e + e - → e + e - , e + e - → μ + μ - and e + e - → τ + τ - , and the total cross-section for e + e - → qq̄ at centre-of-mass energies of 130-140 GeV were studied using about 5 pb -1 of data collected with the OPAL detector at LEP in October and November 1995. The results are in agreement with the Standard Model predictions. Four-fermion contact interaction models were fitted to the data and lower limits were obtained on the energy scale A at the 95% confidence level.
