Scientific American, Vol. 80, No. 16 (1899)
Scientific American, volume 80, number 16, from 1899, is a weekly American periodical of science and engineering news for a general technical readership. The pictures are black-and-white engraved or halftone plates of machines and devices, including a boat-launching gear, a captive balloon being readied on open ground, a novel boiler with cutaway views, and an improved fire-alarm cabinet. A designer could take from them the cross-hatched engraving style, exploded and cutaway views, and the plain labelled diagrams of Victorian machinery.
