Table 7: Comparison of the mean abundances relative to Fe, for normal Population  II stars of Paper II in the metallicity range $-2.6 < {\rm [Fe/H]} < -2.2$, with those for HE 0338-3945. For each element we report the number of measurements N available from Paper II, the mean value of [X/Fe], and the standard deviation of [X/Fe] for the sample, the abundance for HE 0338-3945 ${\rm [X/Fe]}_\star $, and the difference ${\rm [X/Fe]}_\star - \langle {\rm [X/Fe]} \rangle$.
