Scientific paper

Evidence is presented for the existence of a large region of space in Pisces-Cetus that is empty of galaxies and clusters of galaxies. The data base consists of rich clusters from the Abell catalog, galaxies from the CfA survey, and new galaxy redshift data collected at Lick Observatory. The volume of this roughly spherical 40h-1Mpc diameter void is comparable to the largest empty region (free of emission-line galaxies) in the recently completed study of the Bootes void. It is argued that the observed distributions of galaxies and clusters within the Pisces-Cetus void region are unlike that expected for a uniform distribution taking into consideration observational sampling.
