THE INTERRELATIONS OF PURE AND 

 APPLIED CHEMISTRYi 



Within the past fifty years there has 

 been a revolution in civilized industries 

 more f ar-reaehing in its effects than the rise 

 or fall of dynasties or the arbitrament of 

 war. It is a quiet, peaceful revolution, so 

 unobtrusive that even its active agents 

 have rarely been aware of its significance. 

 Even the astounding efficiency of armies 

 in the present European war is but a minor 

 item in the forward movement. 



This revolution, which is still going on, 

 and may continue indefinitely, is both 

 simple and complex. It is merely the 

 gradual substitution of scientific accuracy 

 for empiricism, of quantitative and rational 

 methods for rule of thumlb. It means better 

 service, better wares, intelligent agricul- 

 ture, improved sanitation, the suppression 

 of epidemics, and the prevention of waste. 

 Through its agency the luxuries of a cen- 

 tury ago have become almost necessities; 

 travel has been made easier and cheaper; 

 commerce is broadened ; and all the nations 

 of the earth are now brought together in a 

 community of interests which is only inter- 

 rupted temporarily by war. Even the 

 horrors of war are somewhat mitigated by 

 the beneficent activities of the Red Cross 

 service, which owes much of its effectiveness 

 to the discoveries of science; an effective- 

 ness which would have been impossible in 

 the days of our grandfathers. With the aid 

 of modern inventions the powers not at 

 war are now able to relieve much of the 

 suffering due to war. Steam and the tele- 

 graph have made charity more prompt and
