From this list it would be possible to compile a 

 "Textbook of Physics for the Infra- World." The 

 world, so constituted, has over other imaginable 

 worlds the great advantage that it actually exists 

 before our eyes, though on an exc . minute 



scale. If, therefore, we come upon any impossi- 

 bilities or inconsistencies, we cannot conclude that
