Tractatus de corpore naturale
A Latin mechanics and physics treatise by Charles Becker, printed in 1772 and held by the Smithsonian Libraries, aimed at students of natural philosophy. Its plates are numbered engravings of simple machines, pulleys, levers, balances, hydraulic and optical diagrams, and force diagrams, drawn in clean line with labelled figures. A designer could borrow their tidy schematic style, dense plate layouts, and the framed panels for diagrammatic graphics.
