Now, according to the molecular vortex theory of magne- 

 tism, magnetic force is due to vortex motion in a fluid filling 

 space, and the magnetic force at any point is equal to the mo- 

 lecular rotation of the vortex at that point. Let a, j3, y be 

 the magnetic force at any point. Let F, G, H be the compo- 

 nents of the vector potential or of the electrokinetic momentum; 

 f, g, h the components of the electric current. Then we are 

 to have on this hypothesis,
