Scientific American, Vol. 41, No. 2 (1879)
Scientific American volume 41 number 2, published in New York in 1879, was a weekly magazine of technology and science for engineers, mechanics and general readers. Its pictures are wood-engraved line drawings of machines, including a vertical steam engine and boiler, a gas governor and a graduating index plate, with lettered reference figures and cutaway sections that a designer could use for period mechanical detail and diagram style.
