Goldstein found in 1886 that if the cathode is made with small holes in it, streams of a faint luminous glow will be seen issuing from the holes on the back side of the cathode, facing away from the anode.<ref>Goldstein E. (1886) Berliner Sitzungsberichte, 39, p.391</ref><ref name="Thomson" />{{rp|158-159}} It was found that in an electric field these [[anode ray]]s bend in the opposite direction from cathode rays, toward a negatively charged plate, indicating that they carry a positive charge. These were the positive [[ion]]s which were attracted to the cathode, and created the cathode rays. They were named ''canal rays'' (''Kanalstrahlen'') by Goldstein.<ref>{{cite web | title = Concept review Ch.41 Electric Current through Gasses | work = Learning Physics for IIT JEE | year = 2008 | url = http://iit-jee-physics.blogspot.com/2008/03/concept-review-ch41-electric-current.html | access-date = 2008-11-11}}</ref>
