  We present a comprehensive spectroscopic study of the integrated light of
metal-rich Galactic globular clusters and the stellar population in the
Galactic bulge. We measure line indices which are defined by the Lick standard
system and compare index strengths of the clusters and Galactic bulge. Both
metal-rich globular clusters and the bulge are similar in most of the indices,
except for the CN index. We find a significant enhancement in the CN/<Fe> index
ratio in metal-rich globular clusters compared with the Galactic bulge. The
mean iron index <Fe> of the two metal-rich globular clusters NGC 6528 and NGC
6553 is comparable with the mean iron index of the bulge. Index ratios such as
Mgb/<Fe>, Mg2/<Fe>, Ca4227/<Fe>, and TiO/<Fe>, are comparable in both stellar
population indicating similar enhancements in individual elements which are
traced by the indices. From the globular cluster data we fully empirically
calibrate several metallicity-sensitive indices as a function of [Fe/H] and
find tightest correlations for the Mg2 index and the composite [MgFe] index. We
find that all indices show a similar behavior with galactocentric radius,
except for the Balmer series, which show a large scatter at all radii. However,
the scatter is entirely consistent with the cluster-to-cluster variations in
the horizontal branch morphology.
