Observational data in the alpha (16) Lambda (9) Psi (25)-photometric system for 11 Wolf-Rayet stars and seven planetary nebulae. The results show anomalous alpha (16) Lambda (9)-inches for these emission objects. 6 WR stars show possible variations in the strength of the He II line at 6560 A, perhaps none in the strength of the He I line at 10830 A. In spite of these misconstrued alpha (16) and Lambda (9)-inches, most WC stars are separated from WN stars in the alpha (16) Lambda (9)-array; and PN, in this diagram lie far apart from all kind of stellar objects. The results, yielded by the Psi (25)-index, indicate that the He I and He II lines at 10830 A and 10124 A, respectively, are probably well suited for photometric examination in WR stars, PN and other peculiar objects.
