Preliminary results are reported from a study of ..pi../sup -/p ..-->.. eta..pi../sup +/..pi../sup -/n (eta ..-->.. ..gamma gamma..) at 8.4 GeV/c, using the charged and neutral spectrometer at the Argonne ZGS. Both charged particles and both ..gamma..'s are measured by the apparatus. The data presented from a first-pass analysis of 45 percent of the sample, contain 1,770 eta' (958), 240 D(1285) and a suggestion of E(1420). Cascade decays via sigma(980) ..-->.. eta..pi.. will be discussed. A very clean sample of D(1285) is obtained by a suitable eta..pi.. mass cut.
