CHAPTER V.

MECHANICAL ACTION BETWEEN ELECTRIFIED BODIES.

Article		Page
103.	Comparison of the force between different electrified systems	119
104.	Mechanical action on a specific part original: "element" of an electrified surface	121
105.	Comparison between theories of direct action action at a distance and theories of stress	122
106.	The kind of stress required to account for the phenomenon	123
107.	The hypothesis of stress considered as a step in electrical science	126
108.	The hypothesis of stress shown original: "shewn" to account for the equilibrium of the medium and for the forces acting between electrified bodies	128
109.	Statements of Faraday relative to the longitudinal tension and lateral pressure of the lines of force	131
110.	Objections to stress in a fluid considered	131
111.	Statement of the theory of electric polarization	132

CHAPTER VI.

POINTS AND LINES OF EQUILIBRIUM.


112.	Conditions of a point of equilibrium	135
113.	Number of points of equilibrium	136
114.	At a point or line of equilibrium there is a conical point or a line where the equipotential surface intersects itself	137
115.	Angles at which an equipotential surface intersects itself	138
116.	The equilibrium of an electrified body cannot be stable	139

CHAPTER VII.

FORMS OF EQUIPOTENTIAL SURFACES AND LINES OF FLOW.


117.	Practical importance of knowing these forms in simple cases	142
118.	Two electrified points, ratio 4 : 1. (Figure I)	143
119.	Two electrified points, ratio 4 : — 1. (Figure II)	144
