Proceedings of the United States National Museum
A Smithsonian-issued proceedings volume of the United States National Museum, published in Washington in 1878 for the scientific community and museum staff, whose plates are scientific line drawings. The pictures show tidy black-line diagrams of insect and specimen parts, such as wing venation, genitalia and body segments, labelled with letters a to m, and a designer could borrow their precise, diagrammatic linework and lettered panel layouts.
