Physica
Physica, a 1774 physics textbook compiled by H. Kok and held by the Smithsonian Libraries, presents numbered copperplate diagrams of mechanical and experimental apparatus for teaching natural philosophy. The pictures are precise black-and-white engravings with lettered reference points and labelled parts, showing pulleys, levers, cranes, screw presses, and glass vessels arranged in tidy grids, a useful model for designers planning technical diagrams with callouts and sequenced panels.
