lecting cathode was surroundedby a screen of some solid sub-stance. An experiment made byCrookes * and represented in Fig.31 seems to be an example of this effect, a andb are metal disks, either or both of which maybe made into cathode ; a. diaphragm with twoholes, d and e, cut in it, is placed in… … Fig. 30. 172 CATHODK KAYS is the cathode and b is idle, the rays travel alongthe path df; and when b is the cathode and a is idle,they travel along the path ef. When, however, a andb are cathodes simultaneously, the paths of the raysare dg and eh respectively, the two rays havingthus repelled each…
