The photoneutron polarization from states near threshold was measured, for the first time, for the reaction $sup 208$Pb($gamma$,n$sub 0$$)$$sup 207$Pb throughout the neutron energy range 500 to 1000 keV. Spin and parity assignments were made for these states. The giant M1 resonance in $sup 208$Pb was found to be less fragmented than previously thought. The data suggest that there is some ''missing'' M1 strength in $sup 208$Pb. (AIP)
