Popis:	Medium-resolution observations of nine QSOs whose lines-of-sight pass within 45 h -1 kpc of low-redshift galaxies are presented. Ca II absorption is detected only for QSO 1543+489. With these data, supplemented by previously published results, the Ca II absorption cross-sections of present-day galaxies are analysed by defining an unbiased sample of QSO-galaxy pair for which all observations have been reported, regardless of the success or otherwise of the search for absorption.
