ANALYSIS OF THE GALVANIC PILE. \%\ 



I began by a continuous nle of 76 groups, and continued by 

 their three different dissections with the tripods. 



X. Set of Experiments, wherein the pieces of cloth were im- 

 bibed with pure water. 



Continuous pile. 



This pile being mounter, and remaining insulated, with Experiments 

 onlv the electroscopes applied to its extremities, their indi- J^jfjjkj" 11 * 

 cations, expressed, as they will always be, by the measure 

 of the divergence of the gold leaves in decimals of an inch, 

 were at that moment • 



A, o*o B, 0-4 negat. 



Exp. 1. I tried the shock in the surest manner, which is Exp. 1, 

 to hold in each hand* thoroughly wet, pieces of metal, for 

 which I used uilver <epoons, with a drop of water at their 

 extremity : but 1 did not feel any shock. 



Exp. 2. With the two glass tubes rilled with water, and Exp. J. 

 applied to the pile as represented in fig. 1. 



1. No electric sign remained at the extremities ; a proof, 

 as I shall have an opportunity of showing, that the circula- 

 tion of the electric fluid was produced through the water of 

 the glass tubes. , 



2.. A small stream of calx descended from the wire 1* 



3. Inflammable air ascended from wire 2. 



4. Calx descended from wire 3. 



5. Inflammable air ascended from wire 4. 



The next point which 1 had an intention to examine was, 

 whether there were any possibility to discover the course fol- 

 Jowed by the electric flu'. I in its circulation; whether from 

 A to B, or the contrai way. This brought to my mind 

 what happens to a stream of water when it meets with a 

 yarrow channel in its course ; it rises more or less at the 

 entrance, according to the degree of retardation which it 

 undergoes, and is proportionably lower below the issue. I 

 thought therefore, that, if there were any retardation in the 

 course of the electric fluid passing through the water of the 

 glass tubes, there would b:; some -accumulation of the fluid 

 at its entrance, and deficiency at its issue 3 which might be 



discovered
