Now, if all persons would take the same freedom of thinking for themselves, as Mr. _Freke_ has done, I doubt not but we should soon be as much ashamed of mentioning the _attraction_ of _gravitation_, and the _attraction_ of _cohesion_ &c. as we now are of the _occult qualities_ of the ancient philosophers; and should perhaps, then agree with him, when, speaking of electricity, he says, that “it is a subject which can, with more nobleness and dignity, employ the mind of man, than any he can think of, relating to the sublunary part of the world. For by it you may be acquainted with the immediate officer of God Almighty, which he seems to send to all things living: Nay, this power, (according to his conception,) seems to be the cause, under HIM, both of life and death. And when it may be more fully understood, it may afford us means, whereby we may be better enabled to reason more intelligibly, than now we can, concerning various operations in nature.” Therefore, In the following essay, I shall endeavour to shew, I. How, and from whence, this electrical fire and force are produced; in doing of which I shall make some observations, in order to shew that we may form a more exact idea of most of the great operations of that complete machine, the universe, from electrical experiments, than can be attained by any other means: I shall also produce some experiments which demonstrate, that the terraqueous globe has no _attraction_; nor a solid body, falling towards the earth, any _gravitation_; after which, I shall bring other experiments to prove what is the cause of _solidity_, and by what means bodies _gravitate_ towards the earth. II. How this electrical fire and force act upon the animal frame, and in what disorders they are likely to be of benefit, and in what not.
