SCIENCE 



[Vol. LV, No. 1411 



Women's Dinner, held in the Great Hall of 

 Hart House on Friday evening. Those attend- 

 ing dinners held in the university buildings on 

 Friday evening enjoyed several entertaining 

 surprise features introduced by the Local 

 Committee, including selections by the bag- 

 pipers and the choristers, and several other 

 musical numbers. At most of the dinners 

 toasts were proposed and responded to, with 

 many inspiring after-dinner speeches. 



The programs of the sections and of the 

 societies associated with them were generally 

 extensive, and all were interesting and im- 

 portant. The vice-presidential and presiden- 

 tial addresses will be noted in a later issue of 

 Science, as will also the various symposia of 

 these programs. Special mention should be 

 made here of the program of Section M (Engi- 

 neering) (which presented no program at the 

 recent Chicago meeting), and of the sympo- 

 sium on "An International Auxiliary Lan- 

 guage," which was arranged for Toronto under 

 the auspices of Section K (Social and Eco- 

 nomic Sciences). 



The Engineering program was unusually 

 excellent in many ways. Arrangements for 

 this were due to the very efficient work of Mr. 

 J. B. Tyi'rell, of Toronto, vice-president of 

 Section M. The Society for the Promotion of 

 Engineering Education met with the section. 

 The engineering program began on Tuesday 

 forenoon, with an address on the "Natural 

 Resources of Canada" by the Honorable Sir 

 Clifford Sifton, K.C.M.G., etc., formerly min- 

 ister of the interior, and head of the Conserva- 

 tion Commission of the Dominion of Canada. 

 The program continued through Thursday aft- 

 ernoon, with two sessions each day, many of 

 the papers being illustrated by motion pic- 

 tures. It was concluded by Sir Adam Beck's 

 address on "Hydro-Electric Developments in 

 Ontario," given at the Thursday afternoon 

 general session of the association as a whole, 

 the engineering section furnishing this im- 

 portant feature of the general sessions. The 

 two engineering sessions on Friday were 

 under the auspices of the Society for the 

 Promotion of Engineering Education. A very 

 enjoyable dinner of engineers and geologists 

 was held in the Music Room of Hart House 



on Friday evening, at which a mmiber of 

 inspiring speakers were heard. The president 

 of the university and the general secretary and 

 the permanent secretary of the association 

 were among the guests. 



The social and economic sciences (Section 

 K) had no separate program at the Toronto 

 meeting, but a new symposium topic of very 

 broad interest was introduced under the 

 auspices of this section. Through the enthusi- 

 astic and efficient work of Dr. F. G. Cottrell, of 

 the U. S. National Research Council, this sym- 

 posium was arranged, on "An International 

 Auxiliary Language." It was held at a joint 

 session on Friday afternoon, of Sections K and 

 Q (Education). The symposium was preceded 

 by the delivery of the address of the retiring 

 vice-president of Section K, Dr. Frederick L. 

 Hoifman, of the Prudential Life Insurance 

 Company of America, on "The Organization 

 of Knowledge." Dr. Hoffman emphasized the 

 imperative need for better methods in the 

 classification of knowledge, so that what science 

 has already accomplished maj' become much 

 more easily available. He presented an im- 

 proved scheme of classification that promises 

 to be very valuable in this important and 

 fundamental field of scientific endeavor. Re- 

 lated to Section K was the program of the 

 American Metric Association, which held two 

 sessions on Thursday and a dinner on Thurs- 

 day evening, with papers and addresses favor- 

 ing the more general use of the metric system 

 of weights and measures. 



A program of great general and cultural 

 interest was presented by the Committee on 

 the History of Science, in a session held on 

 Thursday forenoon. Among others, Dr. J. 

 Playfair MeMurrieh — afterwards elected presi- 

 dent of the association for 1922 — gave a paper 

 on the artistic-anatomical work of Leonardo da 

 Vinci. 



Chemical science (Section C) was unusually 

 well represented at the Toronto meeting. Sec- 

 tion C took part in four joint sessions with 

 other sections and associated societies, includ- 

 ing the Canadian Institute of Chemistry and 

 the Toronto Section of the Society of Chemical 

 Industry. A symposium on the Quantmu 

 Theory and a joint session with the Physio-
