Private instructions in the science and art of organic magnetism
An 1885 London self-published manual on organic magnetism, written by Chandos Leigh Hunt Wallace for private students of animal magnetism and healing. Its plate shows a row of small line drawings: hands and arms in passes over a seated figure, a standing nude figure, and diagrams of coils, spirals and arrows with numbered labels. A designer could take the sparse, diagrammatic pen linework and the numbered technical callouts as a model for instructional figures.
