NEW CONCEPTIONS 

 IN SCIENCE 



WITH A FOREWORD ON THE RELATIONS 

 OF SCIENCE AND PROGRESS 



BY 



CARL SNYDER 



Man's happiness and noble aims have rested before 

 now on false foundations. The wisest thing to do, then, 

 is go on enjoying the supreme gifts vouchsafed to us, life 

 and the faculty of seeing the reality. Science will always 

 remain the gratification of the noblest craving of our nat- 

 ure, curiosity ; it will always supply man with the sole 

 means of improving his lot.
