Scientific American, Vol. 44, No. 22 (1881)
A weekly American periodical of 1881 aimed at general readers interested in science, engineering and invention, published in New York. Its pages carry numbered engravings of devices, tools and apparatus, drawn with labelled figures (Fig. 1, Fig. 2) and short captions. The engraving style is precise line work with hatched shading, useful to a designer wanting clear mechanical diagrams of nineteenth-century equipment.
