Abstract
Using CASLEO echelle spectrograms, elemental abundances are derived fo r the sharp-lined nonmagnetic CP stars HR 4487, 14 Hya, and 3 Cen A. T he first two stars are members of the Mercury-Manganese subgroup and h ave abundances which are similar to other such peculiar stars. The thi rd is a hotter related star. The detection of Mn II lines in its spect rum adds to this relationship(1).
