The density of quasars around companion galaxies is computed by a different method than previously (1981), and it is again found that a background density of around twenty times normal is required to explain the apparently associated QSOs. New observations are presented and the correlations between the observed properties of the QSOs and the distances of the central galaxies are investigated. The derived absolute magnitudes and absolute separations are addressed. These quantities in the nearest cases of association are compared to the most distant cases of association that are so far suspected. The possible relation of QSOs to compact, discordant reshift companions which have been observed around spirals in other studies are discussed. Some models of QSO ejection into near association and into the general field are considered. Finally, the subject of background density of QSOs is addressed and comments are made on QSO clustering and the possible relation of QSOs to compact, narrow emission line spectra.
