  Atmospheric parameters (effective temperature, surface gravity) and radial
velocities are derived for 12 candidate blue horizontal branch (HB) stars in
the globular clusters 47 Tuc and NGC 362, which so far have been known to
contain primarily red HB stars. The spectroscopic targets were selected from
the catalog of hot stars detected in these clusters at 1600 A using the
Ultraviolet Imaging Telescope (UIT). Spectroscopic analyses of these stars
reveal, however, that one of the four HB candidate targets in 47 Tuc, and five
out of the eight targets in NGC 362 are probably background stars belonging to
the Small Magellanic Cloud. With the exception of the photometric binary
MJ38529 in 47 Tuc, the parameters of those stars that are probable members of
47 Tuc and NGC 362 agree well with canonical HB evolution. The three hot stars
in 47 Tuc all have 10,000 K < Teff < 15,000 K and include one photometric
binary, which suggests that they might have a different physical origin than
the dominant red HB population. The somewhat cooler blue HB stars in NGC 362
show more continuity with the dominant red HB population and might simply arise
from red giants with unusually high mass loss.
