Studies in spectrum analysis
Studies in Spectrum Analysis is a scientific monograph by the English astronomer Sir Norman Lockyer, published in London by Kegan Paul, Trench, Trubner & Co. in 1904 for specialist readers of spectroscopy. Its pictures are black-and-white diagrams of spectral lines and bands, with one apparatus drawing; a designer might take their strict grid layouts, fine vertical striping and bright-on-dark line patterns as graphic references.
