Artificial dye-stuffs; their nature, manufacture, and uses
A 1917 technical handbook on synthetic dyes by Albert R. J. Ramsey and H. Claude Weston, issued in London by Routledge for chemists, colourists and dye-works staff. Line diagrams show plant layouts, nitrators, filter presses, dyeing machines and benzene-ring formulae, drawn in flat outline with hand-lettered labels useful for schematic, industrial-process and chemical-notation motifs.
