Article number IX in Professor Charles Pellew's series on dyeing, published in The Craftsman. It covers mercerized cotton and the main artificial silks (Chardonnet, Pauly, Elberfeld/Glanzstoff and Viscose): their history, how they are made, and how to dye and finish them. It also gives simple tests for telling natural silk, mercerized cotton and artificial silk apart, and names suitable dye classes (Sulphur, Direct/Salt and Basic colors).
