pie of inductive reasoning the law marks an important stage in the 

 progress of science, and in its simple, generalized form is found to be 

 identical with our present wider knowledge, so long as we avoid such 

 phenomena as the skin effect, the Hall effect and conduction through 

 gases. 



Ohm's law thus experimentally discovered has stood the most 

 exacting tests that modern methods have made possible. It has served 

 as a firm basis for the progress of electrical science and marks the tran- 

 sition from the somewhat haphazard disconnected researches of those 

 who preceded, to the well-directed, consistently developed labors of 

 those who followed him. In a less degree and in a more limited field 

 Ohm did for a branch of electrical science what at an earlier date 

 Newton did for the great field of mechanics.
