We report new measurements of the asymmetry in the deep-inelastic scattering of longitudinally polarized electrons by longitudinally polarized protons in the kinematic range 2 < or = ..omega.. < or = 10, 1 < or = Q/sup 2/ < or = 4 (GeV/c)/sup 2/, and 2 < or = W < or = 4 GeV. We compare our results with the Bjorken sum rule and with several theoretical models of the internal spin structure of the proton.
