The star galaxies seemed to be unevenly distributed in space, more in the northern sky than in the southern. This, however, turned out to be only a small-scale irregularity, tended to disappear when larger sky areas were polled, deeper penetrations into space made, the obscuring effect of dark matter allowed for. Now the galactic distribution in the observable sphere approaches uniformity. Dr. Hubble last week compared the population density to tennis balls 50 ft. apart. This...

The cloud lies well beyond the range of all but very powerful telescopes and is located in the region of the sky that includes the southern constellations, Horologium, Roticulum, and Dorado...
...area surveyed in the catalogue, while containing 7,889 galaxies, each of which fills as much as 5,000,000,000,000 cubic light years, covers somewhat less than one percent of the total sky...
This earlier catalogue included almost exclusively objects brighter than the fifteenth magnitude, and covered the whole sky. The present catalogue deals, for the most part, with objects fainter than the fifteenth magnitude, and confines itself to a very small area...
