The optical lantern, for instruction and amusement
A late nineteenth-century manual on the optical lantern, a magic lantern projector, written by Andrew Pringle and published in New York by the Scovill & Adams Company in 1890 for lantern operators and home amusement. Its pictures are plain wood-engraved diagrams of lantern apparatus, showing mechanisms, burners and fittings in clear outline with lettered reference points, useful to a designer wanting austere technical line drawings.
