58 LIGHT THE RESULT OF FORCE. 



ually determine the extent to which it may be 

 used. 



Professor Anthony, of Cornell University, states, 

 as the result of his experiments in burning kero- 

 sine oil in lamps, and beneath a boiler for power 

 to produce a magneto-electric light, that the latter 

 mode was nearly double in efficiency with the 

 same quantity of oil. With the cost of machin- 

 ery and skilled labor to operate magneto-electric 

 machines, and the inconveniences of employing 

 motive-power on a small scale, the problem of the 

 general use of electric light remains to be practi- 

 cally determined. 1 



These illustrations demonstrate that light and 

 heat, constituents of sunshine, are produced by 

 mechanical impulses imparted to revolve magnets 

 about a central axis ; analogous to the natural 

 revolutions of the magnetic bodies of the planets 

 about the central axis of the solar system, as a 

 sublime magneto-electric machine in continual 

 operation in the heavens. 



1 In view of the great extent of motive-power requisite to operate 

 magneto-electric machines, with the minute extent of its sparks, and the 

 minute amount of motive-power requisite to operate Holtz' electric ma- 

 chine, with its brilliant sparks leaping one or two feet through the air, 

 it may be a question for experimental determination whether this mode 

 of excitation may prove more efficient for illumination with the same 

 amount of motive-power applied to rotate glass, or ebonite plates.
