Présentation de l'éditeur

The following attempt at a mechanical explanation of some of the simpler phenomena of electrification is due to the opinion that the Faraday-M axwell theory, based, as it is, upon the assumption of two electricities capable of neutralizing each others properties, and of attraction 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 explain the phenomena for wrhich 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 stheory 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 wrell to this presentation of the subject by merely changing the necessary plus and minus signs. The Electrical Substance. We have at the present time very definite experimental knowledge of a single electrical substance, divisible into very small particles which are usually associated with other small material particles to make up the ordinary chemical atoms and molecules, but wrhich may exist in bodies
