Scientific American, Vol. 33, No. 2 (July 1875)
A weekly issue of Scientific American from July 1875, published in New York by Munn & Co. for inventors, engineers and patent-minded readers. The engravings are technical line cuts: sectioned valves, bolted flanges, chucks and hand tools, drawn in fine hatching with figure numbers and reference letters, useful as diagram ornament or machine-part silhouettes.
