The envelope function in the largest angular size (LAS) - redshift (z) diagram for 164 quasars for which data are available (Miley, 1971,M.N.R.A.S., 52, 477; Wardle and Miley, 1974, Astron.Astrophys., 30, 305) is discussed. A histogram showing a distribution of LAS of quasars is plotted. making use of the sampling theory, quasars are distributed in compartments having redshift widths of 0.2 and LAS widths of 20 arcsec. The resulting distribution is quite similar to that of figure 3 of Wardle and Miley. It is concluded that the observed distribution of points in the LAS-z plot is just a reflection of the redshift distribution of quasars, and its envelope has no intrinsic physical significance. The LAS and z values of quasars were randomly paired on a computer. The resulting LAS-z plots are quite similar to figure 3 of Wardle and Miley. These results are consistent with our contention that there are no redshifts in quasar spectra. Varshni (1973, 1973, 1974a, 1974b)
