Abstract: (ADS)

We have measured redshifts for 241 galaxies selected from the Zwicky catalog with magnitudes 15.6 or 15.7 in the region (26.5^deg^ <= 32.5^deg^, 8^h^<= alpha <= 17^h^, 1950). This region is the original CfA "Slice of the Universe," which was complete to 15.5; now nearly all Zwicky-catalog galaxies in the region have measured redshifts. These somewhat fainter galaxies outline the same structures as the brighter ones. By examining a sample of 27 galaxies within the most prominent void we find (1) the fraction of absorption-line galaxies is typical of regions outside the cores of rich clusters; and (2) the local morphology- density relation holds within the globally underdense void.
