Shadow Silk. It is the habit of manufacturers of giving names, and sometimes queer ones, to every novelty that is introduced, and frequently the name is a misnomer; or again, a revival of silks or other goods long ago in vogue will be heralded under a new name. The name sometimes attracts as much attention as the goods. Shadow silk is, in reality, only another name for changeable or iridescent silk, a style that has been woven since the " time when the mind of man runneth not to the contrary." The surface of these goods has the appearance of being composed of light and dark tints, which change into intermediate shades with every movement of the wearer, according as the sunlight or sombre light strikes upon it. This is due to the warp being of a high luster and lighter color than the weft. [See Changeable, Shot, Chien]
