Scientific American, Vol. 80, No. 13 (1899)
A weekly American science and engineering periodical from 1899, volume 80, issue 13, published in New York for a general readership of inventors, engineers and tradespeople. Its pages carry technical line engravings of machines and apparatus, plus classified advertising for patents, correspondence courses and cameras. The pictures are crisp black-and-white diagrams, useful to a designer for their clean mechanical linework, stippled shading and labelled plates.
