We report abundance analyses results for three stars whose velocities in the galactic rest frame exceed 400 km s/sup -1/. We have found the following (Fe/H) results: CD --29 /sup 0/2277 (--1.63); HD 134439 (--1.57); G64--12 (--3.52). G64--12 is the most metal-deficient star analyzed to date. We have also obtained other elemental abundances, including (Al/Mg), and we discuss the results of these and other extreme velocity stars whose origins probably lie in the distance galactic halo.
