ABSTRACT
1] Since I first wrote the following paper, I find that this way of accounting for the phænomena of electricity is not new. Æpinus, in his Tentamen Theoriœ Electricitatis et Magnetismi *, has made use of the same, or nearly the same hypothesis that I have; and the conclusions he draws from it agree nearly with mine, as far as he goes. However, as I have carried the theory much farther than he has done, and have considered the subject in a different, and, I flatter myself, in a more accurate manner, I hope the Society will not think this paper unworthy of their acceptance.
