A search has been made for peaks and periodicities in the redshift distribution of a sample of quasars and emission-line galaxies independent of that used in earlier work. In agreement with the results of Burbidge and O'Dell (1972), no statistically significant peak was found at a redshift of 1.95, nor any significant periodicity in redshift in either the sample of quasars alone or the sample of quasars and galaxies together. The strong spectral power peak in their distribution of galaxy redshifts, estimated at a confidence level of 97.5 percent, is completely absent in the present analysis. It is therefore concluded that the observed redshift distribution is consistent with a random sample of discrete values from a smooth aperiodic underlying population.
