THE HUGHES IONIZER.  R. V. WAGNER, M.D.CHICAGO.Electricity is generally conceded to be a mode of molecular motion, and the higher the voltage or tension of the current becomes, the higher the mode of motion. When electricity is conducted through a substance it must impart a mode of motion to its molecular structures, and if this mode of motion is violent enough it disassociates the molecular structures and breaks them up. Very high voltage or high tension currents conducted through the air decompose the elements of the air, producing ozone in large quantities; it is on this principle that ozone generators have been commonly constructed. But the highest tension currents do not impart as high a mode of motion to the molecular structures of the normal air as to those of rarified air; as the molecular structures of rarified air in a vacuum tube may be made to move
