Abstract
We present follow-up spectra of 39 emission-line galaxies (ELGs) from the KPNO International Spectroscopic Survey (KISS). Many targets were selected as potentially low-metallicity systems based on their absolute B magnitudes and the metallicity-luminosity relation. The spectra, obtained with the Lick 3 m telescope, cover the full optical region from [0 II] λλ3726, 3729 to beyond [S II] λλ6717, 6731 and include measurement of [O III] λ4363 in 12 objects. The spectra are presented and tables of the strong line ratios are given. For 12 high signal-to-noise ratio spectra, we determine abundance ratios of oxygen, nitrogen, neon, sulfur, and argon. We find these galaxies to be metal deficient with three systems approaching O/H of 1/25th solar. We compare the abundance results from the temperature-based T e method to the results from the strong-line p3 method of Pilyguin.
