Scientific American, Vol. 64, No. 8 (February 1891)
A weekly issue of Scientific American, published by Munn & Co. in New York in February 1891 for inventors, engineers and general readers following patents and new machinery. Wood engravings mix cutaway sections of valves and fittings with hatched shading, tonal views of triple-expansion engines, and small demonstration scenes of hands working an apparatus — useful for mechanical diagrams and engraved hand studies.
