Excerpt from A Physical Theory of Electrification

The following attempt at a mechanical explanation of some of the simpler phenomena of electrification is due to the Opinion that the faraday-maxwell theory, based, as it is, upon the assumption of two electricities capable of neutralizing each other's properties, and of at traction as the fundamental phenomenon - making repulsion a special case of attraction - has proved inadequate to explain many of the well known phenomena of static electricity, and has broken down completely in attempting to explain current electricity.

I have tried elsewhere to show that the physical lines or tubes of force which are an essential part of this theory are incompetent to ex plain the phenomena for which they were invented, and are inconsistent with our experimental knowledge of facts. It is the purpose of this paper to attempt to show that the mechanical theory of electrification may be greatly simplified by starting with Franklin's theory of a single electricity and by regarding repulsion, rather than attraction, as the fundamental phenomenon.

Since it is the purpose of this paper to present a physical, rather than a mathematical, theory of electricity, no attempt has been made to state the subject in a mathematical form. The quantitative relations of the electric field have been very satisfactorily expressed both in terms of action at a distance and in terms of lines or tubes of force. It is believed that the equations based upon the notion of lines of force will apply equally well to this presentation of the subject by merely changing the necessary plus and minus signs.
