TBE BRITISH ASSOCIATION FOR THE AD- 

 VANCEMENT OF SCIENCE^ 

 ADDRESS OF THE PRESIDENT OF THE 

 MATHEMATICAL AND PHYSICAL 

 SECTION 



It is a great privilege and pleasure to 

 address the members of this section on the 

 occasion of the visit of the British Asso- 

 ciation to a country with which I have had 

 such a long and pleasant connection. I 

 feel myself in the presence of old friends, 

 for the greater part of what may be called 

 my scientific life has been spent in Canada, 

 and I owe much to this country for the 

 unusual facilities and opportunity for re- 

 search so liberally provided by one of her 

 great universities. Canada may well re- 

 gard with pride her universities, which 

 have made such liberal provision for teacb 

 Lng and research in pure and applied sci- 

 ence. As a physicist, I may be allowed to 

 refer in particular to the subject with 

 which I am most intimately connected. 

 After seeing the splendid home for phys- 

 ical science recently erected by the Univer- 

 sity of Toronto, and the older but no less 

 serviceable and admirably equipped labo- 

 ratories of McGill University, one can not 

 but feel that Canada has recognized in a 

 striking manner the great value attaching 

 to teaching and research in physical sci- 

 ence. In this, as in other branches of 

 knowledge, Canada has made notable con- 

 tributions in the past, and we may confi- 

 dently anticipate that this is but an earnest 

 of what will be accomplished in the future. 



It is my intention to-day to say a few 

 words upon the present position of the 

 atomic theory in physical science, and to 



' Winnipeg, 1909.
