For 77 main-sequence F-G stars in the solar neighborhood with published iron, magnesium, and europium abundances and with the ages we calculated the spatial velocities using Hipparcos data and the galactic orbital elements. A comparison with the orbital elements of the globular clusters that are known to have been accreted by our Galaxy in the past reveals stars of the extragalactic origin. We show that the abundance ratios of r- and {alpha}-elements in all the accreted stars differ sharply from those in the stars that are genetically associated with the Galaxy.
