296 MECHANICAL ELECTRICITY. 



Remarks. 



The direction of the current from every indi- 

 vidual metal, and from one metal relatively with 

 another, is at all times invariable, both in me- 

 chanical and therrao Electricity. 



The quantity of force circulating through the 

 galvanometer, and proceeding from any given 

 metal or specific pair of metals, is constantly 

 about the same in amount, proportional to the 

 intensity of the developing process, in both 

 modifications. Each metal evinces an amount 

 of force comparatively proportional with that of 

 every other metal employed, both in the me- 

 chanical and in the thermo Electricity.
