To Preserve Picture

A new method of preserving pictures is being experimented with in London. It consists of placing the surface of the picture, be it canvas or paper, in a vacuum, thus protecting it from atmospheric action. The picture is inclosed in a metal frame or case, covering the back and sides and projecting from the sides like an ordinary frame. A plate of glass is inserted in the edges of the case, just as in the ordinary frame, and hermetically sealed to the metal. The air is then withdrawn from between the surface of the picture and the glass and the painting is in a vacuum. It is believed this plan will effectually protect pictures from the action of dampness, air, gases and other causes that operate to destroy paintings exposed or framed in the ordinary way.
