An attack on Benjamin Franklin and his one-fluid theory of electricity, as well as on his explanation of the charge and 

 discharge of the Leyden Jar, and propounding a new theory ' based on a variety of new experiments.' It is interesting

 is nothing else but the particles which have been diffused from the sun through the diflerent elements of water, 

 earth, and air.'
