Abstract
New abundances are derived for the brightest member of 74 Aqr. The profile of the Mg ii line at 4481 Å is composite and clearly shows three components which confirms the classification of 74 Aqr as a triple SB3 system. The derived abundance pattern confirms the HgMn nature of this star. Helium and magnesium are found to be more deficient than in previous studies while phosphorus is less overabundant.
