Differential photoelectric photometry is carried out in metallic-line stars suspected of variability and in the pulsating Am: star HR 8210. The pulsational stability of classical Am stars is confirmed and the hypothesis that the Am phenomenon is the result of diffuse element separation is still consistent with the observations. The variability of HR 8210 is confirmed too. The behavior of this star should be interpreted as evidence of a multiple-period structure.
