24 INTRODUCTION 



By means of it, in the yesterday of history, a few men 

 discovered much to make us wonder. By means of it, 

 in the to-day of history, many men are discovering much 

 which makes us think and act. And by means of it, in 

 the to-morrow of history, all men will learn to work to-

 in the scientific method. 



In this lesson your teacher cannot help you much, must
