Le magnétisme animal / par Alfred Binet et Ch. Féré.
A late nineteenth-century French scientific study of animal magnetism and hypnosis by Alfred Binet and Charles Féré, published in Paris by Félix Alcan in 1887 for physicians and psychologists. Its pictures are plain pen and line drawings: a cross in hatched fill with radiating strokes, a dense concentric line field around a cross, and a sketched hand, showing how experimental diagrams were built from simple hatching and converging lines that a designer could borrow for optical or radiating-pattern work.
