Fleming in his paper read before the British Associa-tion shows that electrolysis can occur with voltage differ-ence of 1 volt or under, especially if soluble chlorides arein solution in contact with the positive plate. The voltage at which electrolysis commences dependslargely upon the counter electro-motive force of the elec-trolyte. In pure water the voltage is , and in a 10 percent sodium chloride solution it drops to about .37 ammonia, carbonate of soda, potash and the nitratesall tend to reduce below pure water the counter electro-motive force of polarization, and the water adjacent to thesesurfaces underground may be charged with any or all ofthese impurities. If the energy is sufficient, this water maybe decomposed, leaving the oxygen adjacent to the sur-faces from which the curr
