ward with the determination that, though life will never again be 

 as it was in the joyous, care-free past, a new world shall come into 

 being as a compensation for the sacrifices that we are making and 

 are yet to make. We are certain above all things of one result, 

 and it is that this war is forging on the anvil of Destiny, in the 

 fierce f urnace heat of the conflict, the scattered loosely-knit portions 

 of our Anglo-Celtic Empire into an Organization, an instrument that 

 shall be a guarantee of happiness and liberty to countless millions 

 yet unborn. 



It is the thought of all these things crowding in on my mind, 

 that prevents me from adopting the absolutely detached, Olympic 

 mind that Sir Daniel Wilson displayed when your nation was being 

 welded into one in the f urnace heat of the great Civil War. I am 

 not, however, going to allow these thoughts to crowd out those 

 which it is my duty to express to you on this occasion. I must 

 look forward, as you must also, to a time when the welter of baleful 

 hatred and palaeolithic fury of the hour will be past though not 

 forgotten, to a time when men of science of all nationalities may, 

 under better auspices, and in spite of the chauvinism that will be 

 the result of this war, cultivate once more a camaraderie on the 

 intellectual high-road of life. And in looking forward we must 

 strive to strengthen those forces which, out of all the wreckage of 

 today, remain to assist us in restoring what we, two years ago, 

 were wont to believe could never be swept away. 



What are those forces? They are Scientific Truth and the 

 Scientific Spirit, both of them intangible entities or principles, but 

 for all that destined to play a part in the restoration of the world 

 to sanity. 



It is upon these that I am to dwell this evening, and I have 

 chosen them as the subject of my address in the hope that, in hold- 

 ing your attention for the moment, I may direct your thoughts to 

 questions which are of enduring interest to all workers in science. 



To workers in biochemistry these topics are of fundamental 

 importance because our attitude toward them, our comprehension 

 of their significance, determine our usefulness as scientific investi- 

 gators. As students of the phenomena of living matter we are 

 constantly in touch with problems which, to many, seem inscrutable.
