The American journal of the medical sciences
This 1827 American medical journal, published in New Jersey by Charles B. Slack, carried surgical and clinical reports for physicians and surgeons. The single picture is a fine line engraving of a surgical instrument with lettered parts, a screw and two blades labelled a to d, shown in plain outline with hatched shading. A designer could take its clean labelled-diagram style, with letter keys set along the bottom edge, as a model for technical plates.
