56 TWO NEW WORLDS

4. This sketch represents, as closely as we know it, 

 the actual appearances which would be presented to 

 an observer reduced to a size comparable with an 

 electron instead of the earth, who measured his 

 times by the revolutions of his electrons instead of 

 the revolutions of the earth. The events which to 

 us are crowded into a billionth of a second would 

 then appear to occupy several hours, and the tre- 

 mendous and far-reaching chemical and physical 

 changes would be spread over very long intervals 

 of time, making them practically of as little 

 influence to the daily life of the infra-men as the 

 proper motions of the stars are to us.
