Metallic Bodies by Voltaic Electricity. 

 TABLE I.

The law in this case seems, therefore, to be that of a simple 

 inverse ratio of the distance between the plates, except in the 

 near approximations, where the numbers are somewhat less than 

 might have been anticipated. In repeating this experiment, 

 however, the effect on the instrument was, for the most part, 

 exactly in the inverse ratio of the distance between the plates. 



The plates were removed from the acid before observing the 

 effects due to each respective distance, and carefully wiped, and 

 the acid occasionally changed, from a common stock previously 

 mixed in mass. 



5. (b) With a view of ascertaining the law of the action as 

 regarded the quantity of metal immersed, the plates were di- 

 vided, by horizontal lines drawn across them, into seven portions, 

 each an inch wide, and as much dilute acid poured into the cell 

 as was equivalent to immerse one, two, three, &c. of the divisions 

 successively. In the following Table are given the results of 

 this experiment, the plates being carefully wiped, and the acid 

 renewed as before at such trial.
