TEE AMERICAN ASSOCIATION FOR THE 



ADVANCEMENT OF SCIENCE 



SECTION B, PHYSICS AND THE AMERICAN 



PHYSICAL SOCIETY 



At the Boston meeting of the American As- 

 sociation for the Advancement of Science, 

 Section B and the American Physical Society, 

 will in general hold joint sessions for reading 

 papers. The presiding officers will be Dr. L. 

 A. Bauer, of Washington, chairman of Sec- 

 tion B, and Professor Henry Crew, of North- 

 western University, president of the Physical 

 Society. The address of the retiring vice- 

 president of Section B will be given by Pro- 

 fessor Karl E. Guthe, of the University of 

 Michigan. Section B will hold one joint ses- 

 sion with Section A, at which several distin- 

 guished scientists have promised papers which 

 will be of interest to other sections. Another 

 session will be given to the discussion of the 

 teaching of physics, perhaps in conjunction 

 with Section L. 



The program of special papers on research 

 topics will be in charge of the secretary of the 



Physical Society and titles should be sent to 

 him at Ithaca, N. Y. All titles should be in 

 his hands by December 14, accompanied by a 

 suitable abstract. Ernest Merritt, 



Sec. Am. Physical Soc.

 Sec. of Section B, A. A. A. S. 



SECTION A, mathematics AND ASTRONOMY 



Arrangements have been made for two joint 

 sessions of Section A. The first of these is to 

 be held jointly with Section B on Tuesday 

 afternoon, December 28, and the second is to 

 be a joint session with the American Mathe- 

 matical Society on Wednesday morning. The 

 vice-presidential address of Section B is to be 

 given during the former of these sessions and 

 that of Section A during the latter. The sec- 

 tion will organize on Monday morning, and 

 the sessions of Monday afternoon and Tues- 

 day morning will be devoted almost exclu- 

 sively to astronomical papers. Titles and ab- 

 stracts should reach the secretary before 

 December 15. G. A. Miller, 



Secretary of Section A 



SECTION P, ZOOLOGY 



Owing to a clerical error, the preliminary 

 announcement of the Boston meeting wrongly 

 states that a joint session will probably be ar- 

 ranged between Section F and the American 

 Society of Zoologists. The officers of Section 

 F proposed a plan for referring to the Ameri- 

 can Society of Zoologists the reading of all 

 worthy zoological papers by authors who are 

 not members of that society; but it was re- 

 jected by a vote " to keep the meetings of the 

 American Society of Zoologists entirely inde- 

 pendent." As a result, it is planned by the 

 officers of Section F to hold on Friday, De- 

 cember 31, a meeting for reading of papers 

 by members of that section who do not on 

 their personal responsibility arrange for pre- 

 senting their papers in the meetings of the 

 American Society of Zoologists or elsewhere. 

 On the days when that society is reading 

 technical papers, Section F will offer a series 

 of programs designed to appeal to the intelli- 

 gent public and to men of science who are not 

 primarily zoologists. Thus the conflicting
