Scientific American, Vol. 80, No. 18 (1899)
Scientific American volume 80, number 18, from 1899, a weekly American magazine for general readers interested in science, invention and the mechanical arts. Its pages carry engraved illustrations of patented devices, apparatus and workshop equipment, with short captions naming each machine. The pictures are dense black-and-white line engravings with clear outlines and labelled parts, showing how turn-of-the-century instruments, furnaces and cameras were built, which suits a designer studying period mechanical drawing and technical diagrams.
