Scientific paper

The spectra of individual giant stars in 14 distant low-surface-brightness satellites of the Galaxy are compared with those in M92, M15, and M71. The main results of the comparison are that: (1) no gross differences in spectral appearance exist among stars in the dwarf spheroidal galaxies, the outlying globular clusters, and the inner halo clusters; and (2) a large range in metal-line strengths exists at large distances from the galactic center.
