Empirical curves giving the dependence of the equivalent widths of the doublet 2800 Mg II and the line 2852 Mg I on the spectral class have been plotted. Some features of the behavior of these lines in the spectra of stars of the spectral classes A-K have been analyzed. The lines 2795 Mg II and 2852 Mg I have been used to determine the mean electron concentration n/sub e/(Mg) in the atmospheres of 87 stars of the spectral classes B8-K4.
