Anaximander: A Survey of His Ideasrm of stellar relics. I conclude by describing possible manifestations of the enhanced primordial star formation rate that must be invoked for this hypothesis to be viable, and I suggest a possible technique for directly observing halo relics in our galaxy.

Index for 2.2 (System No., References),ion of these 9 pairs provides an interesting constraint on the binary birthrate function, still no useful limits on the dark matter are obtained. In order to investigate the important widely separated pairs ~ 0.1 pc, an order of magnitude more data may be necessary.

1389-2185 s in the Coma and Virgo Clusters of Galaxies. Better optical data has only served to confound their critics and the X-ray data confirms that the gravitational potentials are many times larger than those predicted on the basis of the observed stars. Dynamical analyses of individual galaxies have foun
