  The process e^+e^- --> Z gamma, where the Z boson decays into hadrons or
neutrinos, is studied with data collected with the L3 detector at LEP at
centre-of-mass energies from 189 GeV up to 209 GeV. The cross sections are
measured and found to be in agreement with the Standard Model predictions.
Limits on triple neutral-gauge-boson couplings, forbidden in the Standard Model
at tree level, are derived. Limits on the energy scales at which the anomalous
couplings could be manifest are set. They range from 0.3 TeV to 2.3 TeV
depending on the new physics effect under consideration.
