The giant-resonance region in ${}_{}{}^{208}{}_{}{}^{}\mathrm{Pb}$ was observed by inelastic electron scattering. We present evidence for the existences of a $2^{+}$ (or $0^{+}$) state at ∼ 22 MeV and a $3^{-}$ state at ∼ 19 MeV with giant-resonance character. The resonance states between 8.6 and 11.6 MeV are confirmed to be $2^{+}$ (or $0^{+}$) and the sum of their strengths exhausts about 50% of the $E2\mathrm{}$ sum rule or 100% of $E0\mathrm{}$.
