Editor's Notes
In patent model sent you on lamp with globe withing globe Interpolate "Chemically pure iorn cobalt or nickel drawn in wire may take the place of platinum where the light is not required to be intense, as these metals when perfectly pure can be freed from gas as described & be brought to a vivid incandescence.
