  We present preliminary iron abundances and $\alpha$ element (Ca, Mg)
abundance ratios for a sample of 22 Red Giant Branch (RGB) Stars in the
Sagittarius dwarf spheroidal galaxy (Sgr), selected near the RGB-Tip. The
sample is representative of the Sgr dominant population. The mean iron
abundance is [Fe/H]=-0.49. The $\alpha$ element abundance ratios are slightly
subsolar, in agreement with the results recently prensented by Bonifacio et
al.(2004, A&A, 414, 503).
