Predictions of asymptotically free field theories for scaling deviations of the structure functions are compared with recent SLAC and Fermilab data on deep-inelastic lepton-hadron scattering. Contributions of nonsinglet as well as singlet Wilson operators are taken into account. The latter contributions are found to be non-negligible; specifically it is observed, in agreement with neutrino data, that about 60% of the proton's momentum is due to gluons. The expected quantitative pattern of scaling violations is given for a large range of ..omega.. and Q/sup 2/. (AIP)
