The NA2' experiment at CERN has measured the spin asymmetry in deep-inelastic polarized muon-proton scattering and extracted the spin-dependent structure function g/sub 1/ of the proton. The integral of g/sub 1/ over x was found to be 0.114 +- 0.012 +- 0.026, in disagreement with the Ellis-Jaffe sum rule. An implication is that the quarks account for only a small fraction of the proton spin.
