winding being connected to one brush, and the other end being
connected to or arranged to form one of the circuit terminals,
so that if a current flows from the one brush through the main
winding to the said circuit terminal it will tend to demag-
netize or even reverse the magnet poles upon which the
main winding is wound.

Claims.—(1.) Compound pervious electrodes made of
suitable electro-conducting material and placed in a suit-
able electro-deposition box at suitable intervals between
a simple pervious anode and a simple pervious cathode
in such a manner that the solution to be treated may
pass through said simple pervious anode and said compound
pervious electrodes and then through the simple pervious
cathode, or in the opposite direction, while the electric cur-
rent is passing from the simple pervious anode through the
solution and then in succession through each of the compound
pervious electrodes and out through the simple pervious
cathode. (2.) Pervious electrodes including both simple per-
vious electrodes and compound pervious electrodes contain-
ing fragmental or filamental charcoal made electro-conduct-
