“[The hypothesis of molecular vortices] ascribes the elasticity connected with heat to the centrifugal force of small revolutions of the particles of bodies.”
“Each atom of matter consists of a nucleus, or central point, enveloped by an elastic atmosphere which is retained in its position by attractive forces, and that the elasticity due to heat arises from the centrifugal force of these atmospheres, revolving or oscillating about their nuclei or central points.”
“The vibration which, according to the undulatory hypothesis, constitutes radiant light and heart, is a motion of the atomic nuclei or centers, and is propagated by means of their mutual attractions and repulsions.”

"I have been grinding at many things and lately during this letter at a vortical theory of magnetism & electricity which is very crude but has some merits."
