Limits on anomalous quartic gauge couplings at LEP ------ such paper is going to appear ? ----- The production cross sections for the W+W- gamma, qq gamma gamma and nu nu gamma gamma final states are measured in e+e- collisions at centre-of-mass energies 183-202 GeV with the Opal detector at LEP. The cross sections and angular distributions are used to place limits on anomalous WWgg and ZZgg quartic gauge couplings. Parallel session :5 Plenary session :6a
