摘要：

The relationship between the galactic halo and bulge is discussed, with reference to early results from a survey for K giants in a field 2 kpc from the galactic center, and Zinn's (1992) data on globular-cluster kinematics. The data are currently too meager to decide whether the inner halo shades gradually into the bulge, although there are some interesting kinematical similarities between bulge stars and Zinn's Old Halo clusters in the inner Galaxy. Useful observations that would help decide this matter are also discussed.
