It consists of two sheets of asbestos with wire im-bedded in them enclosed in a cover of flannel. When at-tached by conducting wire cords to the socket of anincandescent lamp the temperature of the pad can beraised to any degree desired and there maintained for anylength of time. An appliance for this purpose can utilizeeither an alternating or direct current. TABLE OF CONTENTS.
