demands of modern industry and agriculture have 

 brought forth more and more extensive professional 

 instruction in all countries. But much remains to be 

 done, and many countries are still backward. 



The progress accomplished by the natural sciences 

 and by the mathematics bound up with them, has been 

 in the past a factor of historical importance. By teaching 

 the history of this progress one can turn out better men 

 by means of the good examples placed before their eyes, 

 and by developing their power of thought. Such in- 

 struction helps to combat the routine spirit; it constitutes 

 a natural introduction to professional instruction, and 

 can thus help to satisfy a social need of our times.
