The correlation between the absorption line density in L-lpha forests and the emission redshift is reexamined using a sample of 15 QSOs with medium to high redshifts with L-alpha forests. The present sample covers a greater range in redshift than in previous paper by the authors, the emission redshifts ranging between 1.715 and 3.780, and the absorption redshifts between 1.501 and 3.780. The statistical method used also differs somewhat. Results of analysis show once again that the absorption-line intensity clearly depends on emission redshift.
