Abstract
We present elemental abundances of 13 microlensed dwarf and subgiant stars in the Galactic bulge, which constitute the largest sample to date. We show that these stars span the full range of metallicity from Fe/H = —0.8 to +0.4, and that they follow well-defined abundance trends, coincident with those of the Galactic thick disc.
