Elemental abundances are derived for four sharp-lined stars, the
Mercury-Manganese stars Lep, HR 4817, and 28 Her, and 7 Sex, a
Population I star with Population II space motions, using REOSC echelle
spectrograms obtained at CASLEO to extend previous studies. Comparisons with
published equivalent widths indicate that the CASLEO scale is marginally
larger than those of DAO Reticon and KPNO CCD spectra. The CASLEO
spectrograms have improved the quality of the abundance determinations.
New abundances are found for a few elements.
