SCIENCE AND INDUSTRY^ 



The present age surpasses all previous 

 epochs of history by the intense activity of 

 the human race, the daring of its efforts,

 influences are at work even in the most re- 

 mote corners of the world ; countries which 

 for ages have been dreaming dreams of 

 rest, countries of which the political, intel- 

 lectual, social or industrial conditions have 

 remained practically unchanged for hun-

 have reached an intensity never witnessed 

 before. 



It looks to me as if all great feats re-
