To compare the globular clusters (GCs) associated with the Sagittarius Galaxy (Sgr) we report the results obtained from new high-resolution spectra of red giant stars in Terzan 8 and Arp 2, collected with the Magellan Inamori Kyocera Echelle (MIKE) spectrograph at Las Campanas Observatory. For Ter 8 we find [Fe I/H] = -2.37±0.04 and [Fe II/H] = -2.30±0.07, while for Arp 2 [Fe I/H] = -1.77±0.04 and [Fe II/H] = -1.89±0.07. Other elements, usually of interest, show the following results. For oxygen, we obtain [O/Fe] = 0.71±0.17 for Ter 8 and [O/Fe] = 0.21±0.22 for Arp 2. For the α-elements (Mg, Si, Ca, Ti), the mean values are 0".37±0.14 dex for Ter 8 and 0.31 ±0.11 for Arp 2. These values are not too different from the Galactic GCs at a similar [Fe/H] value. Regarding Cu, we find quite underabundant results for both clusters: [Cu/Fe] = -0.96 for Ter 8 and [Cu/Fe] = -0.93 for Arp 2. The heavy s-process elements Ba and Nd show no excesses in Ter 8 and Arp 2. Our only r-process element, Eu, shows an excess of 0.45 dex in Arp 2, based on the only useful line at 6645 Å.
