Quincunx is the device used by Galton to illustrate his lectures, which is shown in the Figure. It had a glass face and a funnel at its top. The shot was passed through funnel and cascaded through an the array of pins, every shot striking one pin at each level and in principle falling left or right with equal probabilities each time the pin got hit. The shot then collected in the compartments at the bottom. The resulting outline after several shot were dropped should resemble the normal curve.
