TRANSPARENCY OF METALS.
With the aid of electricity films of several metals of such minute thickness as to allow the light to pass through them can be produced. An electric current is passed into a wire of one of the metals, that extends into'a glass tube containing ratified air or gases. The particles of metal that the electric current loosens from the wire are deposited on the sides of the tube, and form a transparent film. The light that passed through gold was a very handsome green, silver produced blue, copper light green, platina bluish gray, zinc dark bluish gray, and iron brown.
