An 1877 London chemistry treatise by G. Auerbach, edited for English readers by William Crookes, on anthracene and its derivatives such as artificial alizarin, written for dyers and calico printers. The two pictures are structural formulas drawn in ink: a benzoic acid diagram with hexagonal carbon rings and a bridged C6H4 structure, set out as plain linework on a cream page that a designer could use for scientific or diagrammatic motifs.
