The cross section of the process $\rm e^+ e^- \rightarrow Z \gamma\gamma
\rightarrow q \bar{q}\gamma\gamma$ is measured with 215\,pb$^{-1}$ of data
collected with the L3 detector during the final LEP run at centre-of-mass
energies around 205 GeV and 207 GeV. No deviation from the Standard
Model expectation is observed.  The full data sample of 713\,pb$^{-1}$,
collected above the Z resonance, is used to constrain the coefficients of
anomalous quartic gauge boson couplings to: \begin{center}
  \begin{tabular}{ccl}
    $-0.02~\mathrm{GeV}^{-2} <$&$ a_0/\Lambda^2 $&$< 0.03~\mathrm{GeV}^{-2}$ and\\
    $-0.07~\mathrm{GeV}^{-2} <$&$ a_c/\Lambda^2 $&$< 0.05~\mathrm{GeV}^{-2}$,\\
  \end{tabular}
\end{center}
 at 95\% confidence level.
