A one-page dictionary entry on the foulon (fuller) from the Nouveau Larousse Illustré. It defines the term as the worker who fulls and finishes cloth, the fulling mill, fuller's earth, and the bristle fulling machine used in leather dressing, and gives botanical and entomological senses. The technical note describes mallet and pestle fulling mills that beat woollen cloth in alkaline water with fuller's earth. Two engravings show a bristle fulling machine and mallet and cloth fulling machines.
