34 Very — On a Possible Limit to Gravitation, 



far from that of a light-wave will account for the phe- 

 nomenon, if circumscribed by a boundary; but that, 

 otherwise, it is not easy to account for the action on 

 mechanical principles, Hence it is concluded that, some- 

 what as the molecules of gases move in every direction 

 among themselves, but are nevertheless controlled by the 

 more general currents of the larger gaseous mass, so the 

 individual motions of stars, or of lesser star clusters, are 

 local and under the control of a more general movement 

 of the body of aura which contains them. 



According to the kinetic theory of gases, the pressure 

 in a gas is that due to the momentum of the colliding 

 molecules themselves as finally reflected from the con- 

 taining walls of the enclosure. "Without a limiting wall, 

 the given mass of gas would expand indefinitely until its 

 molecules ceased to collide and there would be no pres- 

 sure. In a galactic mass, on the contrary, the individual 

 stellar units do not collide, and the compression is not 

 produced by the onward motion of the stellar "par- 

 ticles," or of their least component atoms ; but it is pro- 

 duced in the containing medium by an internal mechan- 

 ism within the atom itself, thus in an entirely different 

 way. Nevertheless, as in the case of the theory of gases, 

 it is difficult to see how there can be any pressure unless 

 there is a -retaining wall. Such a cell wall for the gravi- 

 tational pressure is presumably a discontinuity in the 

 aura produced by its vortical motion. Thus the aural 

 cell may be likened to a gigantic "vortex-atom. " 



Gravitational Potential is a Strain in the Magnetic Medium 

 caused ~by Electric Stresses. 



Until quite recently, one of the chief characteristics of 

 gravitation has been supposed to be its universality. 

 The attraction of large and small neighboring masses in 

 the Cavendish experiment, the union of sun and planets, 

 and of pairs of suns forming binary stars and separated 

 by distances much exceeding those of the planets, all 

 appeared to follow Xewton's law with remarkable accu- 

 racy, and to be completely dissociated from every other 

 form of physical force. No mode of screening this force 

 has yet been discovered. If limitations to gravity exist, 

 they must be sought in other ways. 



Gravitational potential appears to consist in a state of 

 strain set up in the magnetic medium through the inter-
