Spectrum analysis : six lectures delivered in 1868 before the Society of Apothecaries of London
Spectrum analysis is a lecture series by chemist Henry Roscoe and physicist Arthur Schuster, published in London in 1885 from lectures given to the Society of Apothecaries in 1868. The pictures are plain black-and-white scientific diagrams: spectra shown as dark-lined bands, a graph of intensity against wavelength, a mechanical apparatus with a rotating disc, and a dark disc with radiating corona rays. A designer might draw on their stark monochrome contrast and the clean geometry of the scientific diagrams.
