SCIENTIFIC TRUTH AND THE SCIEN- 

 TIFIC SPIRIT' 



In appearing before you this evening in 

 my present role I can not but recall an inci- 

 dent of fifty-five years ago, whieli often 

 recurs to my mind when I think of the 

 events of to-day. 



The trustees of the Smithsonian Institu- 

 tion in 1861 were preparing their pro- 

 gramme for the year, and in this pro- 

 gramme were courses of lectures to be 

 given to the public on a series of selected 

 topics. Their intention was announced and 

 they were importuned to devote those lec- 

 tures to what was at that time in every- 

 body's mind. It was the first year of your 

 great war of the Secession. I say your 

 war, but I might, with some justification,

 the ranks of the armies of the North 68,- 

 000 British citizens, of whom 45,000 were 

 Canadians, and of the latter 15,000 lost 

 their lives. There were even then stop-the- 

 war people, prototypes of the Fords, the 

 Akeds, the Jane Addamses and the Lloyd 

 Joneses of to-day, futile, mole-visioned and 

 cloister-minded, who imagined that the 

 great conflict could be prevented by talk-

 the opportunity the lectures might present 

 of showing how it could be done. 



The trustees apparently wishe'd to be 

 neutral, perhaps they were uncertain what 

 the upshot of the conflict was going to be, 

 and this may have helped them to decide, 

 as they did, that all war topics should be
