House's patent "relates, first, to constituting the head electrode the terminus of two batteries which may receive the positive (+) and negative (-) from either of the batteries or instruments, or both of the positives from two distinct batteries or instruments, or both negative currents from two distinct batteries or instruments, thus completing a double current through a single electrode, while the opposite poles of the batteries respectively terminate in traversing electrodes upon the sides of the tub, thus completing the circuit of either of both of the batteries or induced currents through any conducting medium placed between the connected electrodes."
