CONSTITUENTS OF THE UNIVERSE. 



ally and fitly the motion of expansion, as may 

 readily been seen from its results. It seems 

 obvious that none of those changes so numer- 

 ous and complex on the surface of the earth 

 would ever take place if there was no motion 

 present but the spiral movements; for such 

 changes only occur through the presence and 

 collision of two or more movements. 



When a projectile propelled at great speed 

 strikes an object like a target, for instance, a 

 change takes place in proportion to the sum of 

 the movements; although not until after the 

 collision occurs. 



In the case of the radial motion from the 

 sun the operation is the same, as no so-called 

 effect from that motion is produced until the 

 earth is reached by it. 



This movement from the sun is so vast and 

 continuous that the results of the bombard- 

 ment are numerous and continuous, as well 

 as complex. Nothing else will account for 

 them but this continued bombardment and 

 collision.
