Scientific American, Vol. 42, No. 22 (1880)
A weekly American periodical of 1880 aimed at inventors, engineers and general readers interested in science and mechanical invention. The pictures are black-and-white wood engravings of apparatus: a seismograph, a balance-type instrument with a clock dial, a drafting machine, and a mining or pumping scene. Their hard outlines, hatching and labelled captions suit a designer wanting nineteenth-century technical diagrams.
