Scientific paper

High-dispersion IUE spectra of the subdwarf B stars UV 1758+36 and Ton S-227 are presented. These spectra are characterized by the presence of a large number of photospheric low- and medium-excitation lines from numerous ions. The lines of C, N, and Si are used in conjunction with local thermodynamic equilibrium (LTE) metal line calculations to derive preliminary abundances for these elements. These results are compared and contrasted with those obtained or the hotter OB and O subdwarfs.
