The anomalous strength of the Fe II 6149 A line relative to the Fe II 6147 A line is confirmed in the spectrum of Mu Leporis and turns out to be caused by a blending with the Hg II 6149.5 A line. This fact reveals that a magnetic field in Mu Lep cannot be reliably detected using the empirical relation for the correlation of magnetic-field strength with the difference between the equivalent widths of the two Fe II lines.
