Text: A German word meaning Rays of Canal. It has been found that by perforating the cathode of a tube producing cathode rays, faint luminous streaks will come through these perforations in a direction opposite to that of the cathode rays. These are called kanalstrahlen. They communicate a positive charge to an insulated conductor. In terms of the electron theory they are positively charged ions. The cathode particle is an electron traveling in one direction, and the kanalstrahlen particle traveling in the opposite direction is what remains of the atom ehich has lost an electron - the cathode particle or ion.
