A measurement of partity nonconservation in the transmission of 800-MeV longitudinally-polarized protons through an unpolarized, one-meter liquid-deuterium target is discussed. The apparatus was essentially the same as for a previous measurement of the effect in {ital p}-{ital p} scattering (V. Yuan {ital et} {ital al}., Phys. Rev. Lett. {bold 57}, 1680 (1986)). The longitudinal asymmetry is measured from the change in transmission of the beam through the target as the helicity of the beam is reversed. The preliminary result is {ital A}{sub {ital L}}=(1.7{plus minus}0.8({ital stat}){plus minus}1.0({ital sys})){times}10{sup {minus}7}. Further study of the dependence of transmission on beam properties should allow the estimate of systematic errors to be reduced and may alter the central value of the result.
