the new tube tubo could never be used as a death ray agaInst humans as an implement lt ot of war With a current ot of of 0 volts the highest yet used in the tube tubo the rays ray's range is only two feet teet and the Inventor believed that by using the highest voltage possible the range could only be extended to top few tew yards An Associated Press representative representative representative
