The measurement of stellar abundances is considered, giving particular attention to questions regarding the reliability of the obtained data. The various determinations of the abundance of iron in the solar photosphere are discussed along with coronal measures of abundance, the construction of a basic solar atmospheric model, and various difficulties regarding the interpretation of spectral lines. It is demonstrated that even for the sun for which good spectra and a reasonably good model atmosphere are available, abundances are very uncertain. In the case of iron, the spectrum of which has been studied more intensely than that of any other element, the solar abundance is not known to better than a factor of at least three.
