it different degrees of rigidity, we can get a 

 glimmering idea of how an atom of matter 

 may be formed from ether. 



Eef erring to the rigidity which motion gives 

 to ordinary matter, it is well known that when 

 two vessels at sea collide the one having the 

 higher speed is not so liable to injury as the 

 one with the lower. The reader will perhaps 

 remember a circumstance said to have oc- 

 curred a few years ago on the Lake Shore 

 Railroad, between Buffalo and Cleveland. 

 The limited express was going west, and while 

 rounding a curve the engineer suddenly came 

 in sight of a wrecked freight train, a part of 

 which was lying on the track where the express 

 train had to pass. The engineer saw that he 

 was too near the wreck to stop his train and 

 that the only way to save his own train and 

 the lives of his passengers would be to cut 

 through the wreck. He pulled out the throttle 

 and put on a full head of steam, and when the 

 train struck the wreck it was going at such a 

 high rate of speed that it cut through without 

 seriously damaging the train and without 

 harm to the passengers. 



There are other heroes beside those who lead 

 armies in battle.
