Fig. 8 represents the phenomenon in a tube with a dome-shaped chamber near the electrode. We seem to have two dissected striae; one on the wall of the tube nearest to the cathode, which provides a beautiful light blue cathode beam thrown into the dome; and another stria on the oppo- site wall of the dome. The original cathode beam excites both positive and negative rays in these sti'ise. Fig. 8.
Text Appearing After Image:
In considering these detached strise it seems that the cathode rays in striking the glass walls can excite both positive and cathode rays. When a spark gap is inserted in a circuit containing a dis- charge tube which is properly exhausted to the striae stage, the latter apparently disappears, the light of the tube becomes more brilliant and fluorescence is generally manifested. This is also the case when a condenser is discharged through the tube. The eye cannot perceive any evidence of stratifications; for the briglitness of the pilot spark, together with the fluores- cence both of the gas and the glass walls, effectually shield any striae of lesser radiance wliich might be present. It is not
