Section of the Physical Science Committee 

 of the National Research Council. — Meetings 

 were held in Hart House, Prof. H. G. Gale 

 acting as chairman. 



It seemed to be the consensus of opinion 

 that the Toronto meeting had been an excep- 

 tionally interesting and inspiring one. Con- 

 tributing to the success of the meeting was the 

 untiring work of the local committees and the 

 cordiality of the members of the University of 

 Toronto and the Royal Canadian Society. The 

 international character of the Toronto meeting 

 was noted by the presence of more Canadians 

 than usual and by the distinguished visitors 

 from abroad. 



The secretary wishes to thank especially 

 those who at the last minute took upon them- 

 selves the work of preparing papers for the 



joint meeting of Section B with the Associated 



Societies. „ .,_„

Secretary, Section B 



SECTION K— SOCIAL AND ECONOMIC 

 SCIENCES 



No separate session of Section K was ar- 

 ranged for the Toronto meeting on account of 

 the recent death of the secretary. Dr. Loomis. 

 A joint session of the section was held, how- 

 ever, with Section Q (Education) on Friday 

 afternoon, December 30, 1921. At this meeting 

 Dr. Frederick L. Hoffman, the recently elected 

 secretary of the section, read an extended ad- 

 dress on "The Organization of Knowledge," 

 subsequently reprinted in Science of March 

 10 and March 17, 1922. Dr. Henry S. Graves 

 of Washington was elected vice-president for 

 Section K for 1922. Dr. Frederick L. Hoff- 

 man, dean of the Babson Institute, Wellesley 

 Hills, Massachusetts, was elected secretary; his 

 term of office will expire January 1, 1925. An 

 understanding was arrived at under which the 

 section, during the curi'ent year, will concen- 

 trate its efforts especially upon conservation 

 problems. The American Metric Association, 

 which is associated with Section K, held ses- 

 sions on Friday morning and Friday afternoon, 

 December 29. During this session, nine papers 

 were read and much discussion was had sug- 

 gestive of the slow but gratifying progress of 

 the metric movement. On Friday evening the 

 Metric Association held its annual dinner, par- 

 ticipated in by a small but thoroughly interest- 

 ed group of members.

 tial address on "The past and the future of
