The American journal of the medical sciences
A periodical of medical science published in the United States in 1827, drawn from the Smithsonian Libraries collection and aimed at physicians and medical readers. Its single plate, labelled Fig. 1, shows hand-drawn microscopic crystal forms in pen and ink with small lettered references, suggesting a practical model for scientific diagrams: star-shaped and cross-shaped crystals scattered across a field with clusters of granules, sparse linework, and lettered callouts set beside each form.
