would certainly suppose that when, from any cause, the two 

 magnetisms had neutralized each other, the further effect of the 

 current —I would be to induce a new and contrary separation 

 of the fluids. 



A comparison between the effects of alternate magnetization 

 on ordinary steel bars, and on magnets formed by electrolytic 

 precipitation, led me to the following results. With respect to 

 the temporary magnetism induced by means of magnetizing 

 currents, electrolytic magnets behave in general precisely the 

 same as ordinary steel bars. 



Plates 11 and 10, and plates 12 and 9, had been originally 

 united, but had been broken apart on removing them from the 

 deposit-plates. 



For the sake of comparison, I subjoin a similar Table of the 

 results observed on the magnetization and demagnetization of 

 three bars of hard steel. 



The succession of the numbers, in columns 9 and 11, is pre- 

 cisely the same as that exhibited by the steel bar. In the ma- 

 jority of my experiments, I found that the magnetism in the 

 original direction continually diminished, as was the case like..
