The present 3800-6700 A line identifications and equivalent widths for the Am star HR 178 were produced by a reduction procedure that used a Fourier transform analysis to suppress high frequencies that are due to photographic emulsion noise. In order to eliminate systematic instrumental effects between these spectra and those of 15 Vul, spectra are also obtained for this star using the same methods. It is found that the best agreements exist among the different abundance determinations for each element from neutral and ionized stages, in both absolute and differential growth curves, for the blue and red spectral ranges.
