Proton-proton elastic scattering at 400 GeVc has been measured in the region 5.4 < -t < 14.4 GeV/sup 2/ with no sign of a second dip or ''break.'' If the data are fitted by exp(At), the slope A decreases from 1.5 +- 0.1 to 0.7 +- 0.2 GeV/sup -2/ over the range. AT fixed t the 400-GeV/c cross sections are about 0.6 times those at 200 GeV/c in this t range. At fixed theta/sub c.m./ = 15/sup 0/, dsigma/dt proportional s/sup -n/ where n = 9.7 +- 0.3.
