Vortices, The sense in which the word "vortices" is used 

 is as expressing the motions communicated to the surrounding- 

 ether by the rush and whirl of the stars, planets, molecules, 

 etc., resulting in vortical force. 



Cyanogen, This is merely a name for an arrangement of 

 material portions, moving at certain speeds, in certain ways; 

 and consequently having certain characteristics. Never let 

 either simple or difficult words blunt your perception of this 

 fundamental truth about substances. 



Physicists, Geologists, etc., know that many modifications 

 of physical law are brought about by physical law, by the 

 formation of cements, by pressures, etc., etc. These have not 

 been mentioned in detail. I have given the outline, the filling 

 in and decoration is left to abler hands to perform at their 

 inclination and leisure. 



Maintenance of Energy. Professor S. Arrhenius is the 

 author of one theory on this subject, and there are others. 

 The potential is acknowledged to exist. 



Recapitulation, The author has endeavoured to show that 

 " All *mass is mass of the ether, all momentum, momentum of 

 the ether"; and that the ether is matter. Change is caused 

 by material motion, and collisions of the masses, or the ether. 

 Electricity and magnetism are material motion in a certain 

 condition of stress. Gravitation is a result of vortication caused 

 by the natural motions of the ether, and the ether masses. 



* Professor Sir Joseph John Thompson, Cavendish Professor of 

 Physics, Cambridge.
