A continuation (from the August issue) of a series on designing patterns based on Mohammedan or Saracenic art, covering complex arabesque patterns. It explains how to construct them from primary construction lines (polygons in contact such as octagons, decagons, pentagons, heptagons and sixteen-sided polygons) and secondary construction lines (circles and radii), with worked examples in Figs. 8-13. It closes with remarks on accuracy, symmetry and avoiding monotony in geometric ornament. The scan ends with the opening of an unrelated article on sizing cotton yarns.
