Scientific American, Vol. 34, No. 12 (1876)
A weekly American periodical of 1876 devoted to science, invention and mechanics, printed for engineers, inventors and general readers. Its pages carry engraved working drawings of machines, apparatus and ships, with figure labels and captions beneath. The engravings are crisp and diagrammatic, with hatched shading on cylinders, gears and hulls, useful to a designer for mechanical line work and technical layout.
