Scientific American, Vol. 80, No. 15 (1899)
Scientific American volume 80, number 15, from 1899, is a weekly American magazine of mechanical and scientific news for engineers, inventors and general readers. Its pages mix engraved technical diagrams with dense trade advertisements for pumps, pulleys, gasoline engines and water filters. The engravings are crisp black line drawings of machines, plumbing and pipework, useful to a designer for their clear structure, hatching and labelled parts.
