This experiment does not fucceed in 
frogs, but if the coatings are made ufe of 
as mentioned in Section I, it never fails of 
fuccefs. It fhould feem that the coatings 
increafe the want of equilibrium (Sbilan- 
eio) of the animal electrical fluid. 
This conjecture will be found far from 
unreafonable, when we refleCt, that elec¬ 
tricity is a matter endued with extreme 
mobility, and that trifling accidents are 
capable of making it experience modifi¬ 
cations and changes, particularly in anir 
mated beings, in whom it exifts in a ftate 
of activity. 
I do not wifh this opinion to be taken 
for granted, as I am myfelf not entirely 
convinced of its being founded. But J 
would by no means have it happen that 
an incapability to explain the phenomena 
produced by two different kinds of metal, 
ihould be a reafon for renouncing the doc¬ 
trine of animal electricity,
