Results of a search for new planetary nebulae on a quarter of the Palomar Observatory Sky Survey (POSS) E plates are reported. A total of 218 prints evenly scattered over all accessible galactic longitudes and latitudes was examined, in addition to the entire region between longitudes 33 and 213 deg and latitudes + or - 2 deg. Five objects satisfying the criteria of emission nebulosity characteristic of planetary nebulae and/or a central blue star were detected, as well as another three dozen very faint, roundish unlisted objects. The coordinates, dimensions, central star magnitudes, surfaces brightnesses, nebular magnitudes, volumes and estimated distances of the five probable planetary nebulae are presented, and it is noted that all but one of them are of considerably low surface brightness.
