Is and we cannot help thinking that in every place where we find these lines of force some physical state or action must exist in sufficient energy to produce the actual phenomenaMy object in this paper is to clear the way for speculation in this direction by investigating the mechanical results of certain states of tension and motion in a medium and comparing these with the observed phenomena of magnetism and electricity By pointing out the mechanical conseuences of such hypotheses I hope to be of some use to those who consider the phenomena as due to the action of a medium but are in doubt as to the relation of this hypothesis to the experimental laws already established which have generally been expressed in the language of other hypothesesI have in a former paper endeavoured to lay before the mind of the geometer a clear conception of the relation of the lines of force to the space in which they are traced By making use of the conception of currents in a fluid I showed how to draw lines of force which should indicate by their number the amount of force so that each line may be called a unit line of force and I have investigated the path of the lines where they pass from one medium to another.

On Physical Lines of ForceKnown then if we draw a line so that in every part of its course it coincides in direction with the force at that point this line may be called a line of force since it indicates the direction of the force in every part of its courseBy drawing a sufficient number of lines of force we may indicate the direction of the force in every part of the space in which it actsThus if we strew iron filings on paper near a magnet each filing will be magnetized by induction and the consecutive filings will unite by their opposite poles so as to form fibres and these fibres will indicate the direction of the lines of force The beautiful illustration of the presence of magnetic force afforded by this experiment naturally tends to make us think of the lines of force as something real and as indicating something than the mere resultant of two forces whose seat of action is at a distance and which do not exist there at all until a magnet is placed in that part of the field We are dissatisfied with the explanation founded on the hypothesis of attractive and repellent forces directed towards the magnetic poles even though we may have satisfied ourselves that the phenomenon is in strict accordance with that hypothes.
