HE principal result of my paper onr the Analysis of the Galvanism 



Galvanic Pile has been to show, that by this instrument, in ^''°7^ ^^.^^ * 

 ' -^ ' modification ot 



which Sig. Volta has so much extended Sig. Galvani's first eleciricity by 

 discovery of some physiological effects produced by two ^°^^^'^P"^' 

 associated metals, we have been really enabled to deter- 

 mine whence proceeded that action upon the animal eco- 

 nomy. When these effects were discovered by Sig. Galvani, 

 appearing similar to the shock produced by the Leyden vial, 

 they pointed out some action of the electric Jiuid: but when 

 this ^uirf acts thus upon our organs, it is also manifested 

 by electric motions and by sparks; whereas not even the 

 first of these signs appeared in the galvanic experiments. 

 Therefore the action of the electric fluid in these iirst phe- 

 nomena might for ever have remained doubtful, had not. 

 Sig. Volta, by the invention of his admirable pile, increased 

 that action, so as not only to be attended with electric mo» 

 tions and sparks, but to produce some chemical effects known 

 before to belong to the electric jluid.
