Bulletin - United States National Museum
This is a government museum bulletin issued by the United States National Museum under the Smithsonian Institution and the Department of the Interior, printed in Washington in 1877 for scientific readers. Its pictures are plain line engravings and photographs of laboratory apparatus, including a magnet with coil, a zinc and steel cell, numbered gear-like discs, and a drum-and-spring instrument, showing clear diagrams a designer could borrow for technical, scientific-looking graphics.
