Standardized UBV photometry
of seven early M emission-line dwarfs, seven Mira stars, and also SS Cygni is
presented. The dMe stars have not been previously observed in the UBV system to
the accuracy presented here. The short time scale ( < 1 min.) variations
observed in the light output of SS Cygni are similar to those found by Walker
and Chincarini (1968).
