Rational recreations, in which the principles of numbers and natural philosophy are clearly and copiously elucidated by a series of easy, entertaining, interesting experiments. Among which are all those commonly performed with the cards
A 1787 London book of scientific recreations by William Hooper, M.D., published by L. Davis and others, meant for home amateurs learning mechanics and arithmetic through simple experiments. Its copperplate plates are framed diagrams of levers, pulleys, a wheeled cart, a windmill-like device, a counting frame and a water-driven apparatus, drawn in fine crosshatched line with lettered keys and small figures for reference.
