  • The anodes and cathodes in each vessel are connected up in parallel similar to an ordinary storage battery, but the five electrolytic vessels are connected up in series. 
  • The installation consists of five large electrolytic vessels, each of which is fitted up with five anodes and six cathodes arranged alternately. 
  • The two faces of the cathode seem to emit rays which are deviated in a direction perpendicular to the lines of force by an electric field, and do not seem to be electrified.
