Merrill, Paul W. ; Greenstein, Jesse L. Abstract Spectrograms, dispersion 4.5 A/mm in the blue region, 6.8 A/mm in the visual, obtained with the 200-inch telescope, form the basis of this article. A list of 1500 absorption lines and band heads from 4000 to 6900 A is in Table 7. The behavior of lines of the rare earths and of other heavy elements including technetium is briefly described. The displacements of lines of 6 neutral metals increase algebraically with excitation potential of the lower level. This work is preliminary to a discussion of chemical abundances in the atmosphere of R Andromedae.
