When the magnet was, however,brought down over the further part of the tube, so that its poles were one on eachside of the tube, with the blue cone of rays between, the cone of rays was absolutelyunaffected. That these rays were really rays of some kind was proved by thecircumstance that they could cast shadows. A scrap of glass which accidentallyremained inside the tube was observed to cast a shadow behind itself, none of thetawny fluorescence appearing in the shadowed portion. To investigate the phenomenon further, tube [No. C 11], (fig. 20), was then the cathode there was introduced a screen of iron wire gauze, mounted upon Mg.
