INFRA- ASTRONOMY 47 



These chains will make the structure of the magnetic 

 elements more complex than that of non-inagnetic 

 elements. 



When two atoms come into contact without being 

 crowded by others, as, for instance, in a gas, it may 

 well happen that one of the electrons gets detached 

 from one atom and describes an orbit round the 

 other. It is just as if a Centauri, for instance, were 

 close enough to our solar system to capture Neptune. 

 With a suitable speed, the two solar systems would 

 combine and revolve about each other, and our 

 system would become a double star like most of 

 the other visible stars. 



2. Now, imagine two neutral atoms in the infra- 

 world. To the infra-man they appear as stars or 

 suns, not necessarily single spheres, like our sun, but 

 possibly larger aggregations of such spheres, like 

 heaps of cannon-balls, prevented from coalescing by 

 their strong cohesion and great hardness. Each of 

 these suns, whether simple or composite, is surrounded 

 by electrons revolving in all directions as irregular 

 as the satellites of Uranus or the new satellite of 

 Saturn. The total charge of the electrons is neutra- 

 lised by the positive charge of the central body, so 

 that any single electron, removed some distance from 

 the system, is subjected to an attraction equal to the 

 repulsion between two electrons at the same distance. 

 The system from which the electron is removed 

 becomes what is called a " positive atom." If, on
