Scientific paper

There are now six known dwarf elliptical galaxies outside the Local Group (mostly in the Virgo and Fornax clusters) that appear to contain globular-cluster systems of their own; all of them were discovered accidentally during surveys for other purposes. All six of these are nucleated (dE, N) dwarfs. This evidence, although quite preliminary, supports the suggestion of Ferguson and Sandage that nucleated dwarfs are 'genuine' E galaxies, generically more strongly related to large E/S0 galaxies than are nonnucleated dwarfs of the same luminosity level. A more systematic search for globular cluster in both types of dE's is recommended.
