The synthetic dyestuffs and the intermediate products from which they are derived
A 1905 London technical manual by chemists John Cannell Cain and Jocelyn Field Thorpe, published by Charles Griffin for industrial chemists and dye works staff. Line engravings show laboratory glassware in outline — flasks, condensers, U-tubes, funnels and burners on ring stands — usable as clean apparatus diagrams, hatched-tube textures, and numbered figure layouts.
