the result that dextrous are torn loose and forced in the direc- 

 tion DC, or in the direction in which the spiral is moving at 

 0, and the motion of the line is absorbed as above. This is 

 in accordance with the well known laws of induction. 



This explanation of induction was suggested by Mr. A. N. 

 Hatherell, instructor in physics in the Los Angeles Polytechnic 

 High School. 



The tearing loose of the electron is thus a resultant of 

 two motions ; one, the swelling out of the line of force in a 

 plane perpendicular to the conductor and the other the motion 

 of the line in a spiral. If the line be still, due to a steady 

 current in BA no induction takes place. The force exerted at 

 offsets the force exerted at N and no electrons are torn 

 loose. 



It must be remembered that the direction of the line of 

 force about the electric current is only assumed. Whether 

 a line of force rotates right-handedly or left-handedly is not 

 known. It is assumed for the sake of convenience that the 

 lines of force rotate right-handedly around the electric current, 

 as one looks in the direction in which the current is flowing. 

 The absolute direction remains to be proven. If the field due 

 to a stream of dextrons rotates right-handedly then the field 

 due to a stream of levulons rotates left-handedly as shown 

 by the transformer experiment. 



This transformer experiment also demonstrates that the 

 electric current is a stream of electric charges. Electric charges 

 collect on insulators when rubbed. They also collect on in- 

 sulated conductors when rubbed. The bullet fired from a 

 cannon is an insulated conductor, if of metal, and insulated 

 also if a nonconductor. When these rub against the air they 

 become charged either negatively or positively. These moving 

 positive or negative charges act exactly like a current of elec- 

 tricity in a conductor; hence the electric current in a con- 

 ductor is .a stream of electric charges. 



When these electrons are torn loose from the atoms, it 

 is very probable that one electron only is torn out of a uni- 

 valent atom, because no matter what the mass of the atom, 

 the positive charge remaining upon it always has the same 

 value. Why the dextron alone is torn out. and the levulon is 

 never torn away, are questions that cannot yet be answered. 

 The number of dextrons torn away depends upon the valence 

 of the atom, and the positive charge remaining or released by 

 the tearing away of the dextrons depend upon the same thing. 

 If it were possible to tear away more dextrons, and also the 

 levulons, the atom would suffer complete disintegration into 

 electrons. AVhether this occurs or not we do not know. 



Helmholtz and Lord Kelvin assumed a vortex structure 

 for the atom. This would make the atom an indivisible entity. 

 i. e. an entity that would break up into a disorganized mass of 

 particles that constitute the vortex. It may be, however, that
