Scientific American, Vol. 33, No. 5 (1875)
Scientific American volume 33, number 5, published in New York in 1875, is a weekly periodical for a general readership of inventors, mechanics and engineers, reporting new patents and technical devices. Its pictures are precise black-and-white line engravings of mechanisms, apparatus and boiler sections, showing internal construction through hatching, cutaway views and labelled figures a designer could borrow for technical diagrams and vintage engineering graphics.
