Color-blindness and color-perception
Color-blindness and Color-perception is an 1882 New York study by Swan Moses Burnett, issued by D. Appleton and held by the Royal College of Surgeons of England, written for physicians and readers of vision science. Its pictures here are plain line drawings of swords and blades from a weapons section, numbered and labelled by region and period, showing curved, straight and thrusting forms that a designer could use for historical outline references.
