The H. W. Johns-Manville Company, 100 William Street, New York, has issued an advertising bulletin of original design. It is a heavy piece of cardboard having split-leaf covers on each side which open in the center disclosing the card within. Upon one side of the card is shown an ordinary hot-water bag generally used for applying heat locally to the body. This is "the old way." On the other side — "the new way" — is the "electrotherm," a device manufactured by the company which is designed for the same purpose. It consists of wires insulated and protected by asbestos woven into a light pad which, when attached to an ordinary incandescent lamp cord, offers sufficient resistance to produce a constant and uniform heat.
