One of the great achievements in connection with electricity during the last year was the production of ductile tungsten. That rare metal has been known for a hundred years, and all attempts to produce it in ductile form have been defeated. American scientists have at last been able to draw it into a wire the tensile strength of which is superior to piano steel. This will be of great advantage in the manufacture of tungsten lamps. These new lamps are very strong.
