ANALYSIS OF THE GALVANIC PILE, ]QJ 



II. Set of Experiments : wherein the pieces of Cloth were Exp. -wick

Continuous Pile. 



Exp. 7. In order to have a point of comparison of the Exp 7, 

 respective electric effects of the two liquids, I first mounted 

 the continuous pile of 76 groups with p«r<? water in the 

 c/ofA, and observed the electroscopes at its extremities: they 

 were this day A, O'l pos. ; B, 0*3 negat. I then imbibed the 

 cloth with the solution of marine salt, and the electroscopes 

 had the same indications. 



Exp. 8. Concerning the shock. Exp. 8- 



1. In placing my fingers, when dry, on the extremities 

 of the pile, I felt no shock. 



2. My fingers being wet, I felt a small shock. 



3. Taking then the silver spoons 9 as above indicated, 1 

 had a shock up to the elbow. 



4. Whenever I withdrew one of the spoons, on jbringing 

 it again into contact, I felt a new shock ; but when, after 

 having felt a shock, I kept both spoons steady on the extre- 

 mities, all sensation ceased. This is an important fact, to 

 which I shall refer hereafter. 



Exp. 9. I applied the two glass tubes as in Exp. 2. Exp. 9. 



1. Every circumstance, with respect to chemical effects in 

 the water, was the same, except that these effects appeared 

 sooner, and were stronger ; and every visible electric sign 

 ceased at the extremities of the pile as in the other experi- 

 ments. 



2. I tried the shock with the spoons ; it was not quite so 

 strong as before the glass tubes were placed. I fixed also 

 both tubes on the extremities of the pile ; every sensation 

 ceased, but observing then the chemical effects in the water 

 of the tubes, I saw, by the quantity of hifiammahle air 

 emitted, that they were reduced to about the half of their 

 intensity: whence it appears, that my body was a conductor 

 of the same nature as water. 



3. Taking off the ring which connected the glass tubes 

 by the hooks of their lower wires, and placing the angle of 

 the handle of one spoon in one of these hooks, when I 



touched
