Parrish was an observer at Leander McCormick Observatory of the University of Virginia, Charlottesville. In his time Ormond Stone was director (1882-1912). Stone's first assistant was Francis Leavenworth and Parrish became his successor in 1887. A fourth observer, contributing to the discovery of new nebulae, was Frank Muller. The observations were made from 1887-90 with the 26¼" Clark refractor (erected in 1874) using a magnification of 175.
Parrish discovered 5 IC-objects. They are published in: Stone, O., Southern Nebulae, Publ. Leander McCormick Obs. 1, 173 (1913). Generelly the positions are not very precise. IC 953 is only a star; IC 955 and 957 are lost ("not found"). IC 1496 was re.discovered by Edward Swift a year later.
