Abstract

A comparison of the Mg II resonance lines in Am and none Am stars of similar effective temperatures does not show any measurable differences. The Mg I resonance lines may be weaker in the Am stars. The mechanism reducing the Ca II K line intensities in Am stars does not work for the Mg II k and h lines.
