the molecules and atoms. Chemical 

 affinity is a result of attractions amongst 

 molecules and atoms ; and gravitation a 

 result of attractions amongst masses. 8 



The expression " matter and motion/' 

 or " matter and force," is misleading. It 

 is true there is motion, and that there could 

 not be motion without matter ; but it 

 is equally true that there could be matter 

 without motion, that is, if motion were 

 not innate in matter. Neither is the 

 formula " matter affected by motion " any 

 more satisfactory, because it implies the 

 separate existence of motion motion 

 acting on matter. Now, motion as a 

 separate existence is an absurdity : there 

 is no such thing. 9 The most satisfactory 

 formula is " matter in motion " : this is 

 in conformity with the fact that the atoms 

 have innate motion that motion is innate 

 in matter. 



8 " One thing seems certain, if the vortex-ring theory oi 

 matter be true, or anything like it, then ' gravity ' must 

 follow from the structure ; for in the absence of any evi- 

 dence of the existence of gravitation in the ether, no one is 

 at liberty to postulate it there for the sake of the definition 

 of matter. It must be looked for as due to the particular 

 kind of motion that constitutes the atom." DOLBEAR, 

 P- 349- 



9 " Pure motion, motion by itself, is impossible to thought." 

 DALLINGER, p. 23. 



[So also is separate ' force.' J.W. H.]
