Chap. XII The Identity of Galvanism With Electricity Considered
It has been supposed by many, that the phenomena of Galvanism and electricity depend upon the same cause. Others, however, controvert this opinion, and affirm that Galvanism is a fluid sui generis. That there is a great similarity between some of the phenomena of Galvanism and those of the electric fluid, is evident; but this analogy cannot be traced in every instance.
It is not our province to enter into this controversy; we shall only relate a few facts upon which it is founded, and leave the speculative reader to draw from them his own conclusions.
