Outlying condensations of ejecta from eta Carinae have nebular emission-line spectra, which are easier to analyze than the spectrum of the central object. Here we report some ground-based and IUE observations of the brightest outer condensation. It appears to be nitrogen rich; five ionization states of nitrogen but none of carbon or oxygen are observed. This is perhaps the most definite known clue to the evolutionary status of this very massive star.
