The American journal of the medical sciences
The American Journal of the Medical Sciences is a periodical published in 1827 in Thorofare, New Jersey, by Charles B. Slack and others, aimed at physicians and medical readers. Its pictures are line engravings of laboratory and experimental apparatus: a thermometer-like tube in a jar of liquid, a series of graduated glass vessels in stages, and a flask heated over a spirit lamp connected by bent tubing to two gas-collecting jars. A designer could take from them the clean, diagrammatic style of early scientific instruction drawings, with fine parallel hatching to suggest liquid and glass.
