Intermediate-band photometry has been used to derive effective temperatures, metal abundances, and surface gravities of nine stars of the dwarf Cepheid group of variable stars. A strong correlation exists between the metal-line strengths and the period of pulsation in the sense that the shorter-period stars have weaker metal lines. The dwarf Cepheids are evidentally found among both population I and population II stars.
