We have remeasured the total cross section for proton-proton scattering at 2-6 GeV/c in the spin states \ensuremath{\uparrow}\ensuremath{\uparrow} and \ensuremath{\uparrow}\ensuremath{\downarrow} perpendicular to the beam direction. With the reduced errors significant differences were found between the two cross sections.
