Before I conclude, I would beg one Thing (if it be not too great a Favour) from the Gentlemen of the Faculty (physicians), and indeed from all who desire Health and Freedom from Pain, either for themselves or their Neighbors. It is, That none of them would condemn they know not what: That they would hear the Cause, before they pass Sentence: That they would not peremptorily pronounce against Electricity, while they know little or nothing about it. Rather let every candid Man take a little Pains, to understand the Question before he determines it. Let him for two or three Weeks (at least) try it for himself in the above-named Disorders. And then his own Senses will show him, whether it is a mere Play-thing, or the noblest Medicine yet known in the World.
