Conclusions. 



1. A Crookes tube enclosing a continuous conductor is well 

 suited, with the employment of high electromotive force, for 

 the study of electric lines of induction. 



2. The direction of the so-called X-rays and cathode rays 

 can be changed by electric induction. 



3. The so-called X-ray burn can be produced by an intense 

 state of electrification. 



4. The so-called cathode rays and X-rays are given off from 

 every element of a continuous conductor at a high stage of the 

 vacuum in a Crookes tube, both when this conductor consti- 

 tutes the cathode and when it forms the anode of the electri- 

 cal circuit. The term electric rays, possibly rays of polariza- 

 tion, would appear to be more comprehensive than the terms 

 cathode rays and X-rays.
