The Goddard High Resolution Spectrograph (GHRS) of the Hubble Space T elescope (HST ) has been used to obtain spectra of the 2500 region in eight stars with metallicities ranging from Fe/H \ [0.4 to [3.0, including the most metal-poor star ever observed for boron. Spectrum synthesis utilizing latest Kurucz model atmospheres has been used to determine the B abundance for each star, with particular attention paid to the errors of each point, to permit judgment of the quality of the t of models of Galactic chemical evolution. Previous observations were combined with new ones, bringing the number of stars analyzed to 11.
