Abstract:
    Ussing CASLEO echelle spectrograms, elemental abundances are derived
    for the sharp-lined non-magnetic CP stars HR 4487, 14 Hya and 3 Cen A.
    The first two stars are members of the Mercury-Manganese subgroup and
    have abundances which are similar to other such peculiar stars. The
    third is a hotter related star. The detection of Mn II lines in its
    spectrum adds to this relationship.
