On the source of power in the voltaic pile
A Royal Society paper printed in London in 1840 by Michael Faraday, with plates engraved by James Basire, presenting experimental research on electric batteries for a scientific readership. The first picture is a framed armillary sphere held up by a sculpted figure, drawn in fine black line on a yellow ground; the second is a technical wiring diagram of two glass cells with platinum, iron and a galvanometer, labelled with letters and a Phil. Trans. header. A designer could draw on the crisp engraved linework, the ornate sphere cage and the plain schematic labelling style.
