  Although evidence is accumulating that abundance ratios in galaxies are often
non-solar, they are far from understood. I resume the current evidence for
non-solar abundance ratios, supplementing the recent review by Worthey (1998)
with some new results. It appears that the Mg/Fe abundance ratio only depends
on the mass of the galaxy, not on the formation time-scale. For massive
galaxies [Mg/Fe] > 0, while small galaxies show solar abundance ratios.
Information about abundances of other element is scarce, but new evidence is
given that [Ca/Fe] is solar, or slightly lower than solar, contrary to what is
expected for an alpha-element.
