liquid is somewhat inflammable but not 

 explosive. 



I have constructed a generator which 

 answers all purposes and is safe. I am in 

 hopes of having them made in quantities, so 

 that if necessary, this culicide can be used 

 extensively. It is absolutely certain that 

 this culicide and disinfectant injures noth- 

 ing but living things — the most delicate 

 fabrics, metals, etc. I -would be pleased to 

 give any information to any one as to its 

 efSeieney. For lack of time, I can not 

 speak further of this most wonderful agent. 



I thank you all for your kind attention.

SECTION B— PHYSICS. 



The annual meeting of Section B, Phys- 

 ics, of the American Association for the 

 Advancement of Science, was held in the 

 Physical Laboratory of Tulane University, 

 in New Orleans, on December 29 and 30, 

 1905, and on January 1, 1906. The pre- 

 siding officer was the vice-president of Sec- 

 tion B, Professor Henry Crew, of North- 

 western University. The other officers in 

 attendance were the retiring vice-president, 

 W. F. Magie; the secretary, D. C. Miller; 

 member of the council (no election) ; mem- 

 ber of the general committee, H. T. Eddy ; 

 members of the sectional committee, Henry 

 Crew, W. F. Magie, D. C. Miller, A. Trow- 

 bridge (elected at this meeting to serve for 

 five years), E. L. Nichols and F. E. Nipher; 

 press secretary, J. R. Benton. 



It was decided by the general committee 

 that the next annual meeting would be held 

 in New York City in convocation week, 

 1906-7 ; and that those sections desiring 

 to do so might hold a summer meeting in 

 Ithaca in the latter part of June. The 

 desirability of such a meeting for Section 

 B will be determined by letter ballot. The 

 presiding officer for these meetings will be 



the vice-president elect, Professor W. C. 

 Sabine, of Harvard University. The other 

 officers for these meetings, so far as now 

 determined, are: 



Retiring Vice-President — Henry Crew. 



Members of the Sectional Committee — W. C. 

 Sabine, Henry Crew, D. C. Miller, A. G. Webster, 

 G. F. Hull, F. E. Nipher, E. L. Nichols, A. Trow- 

 bridge. 



Secretary — Dayton C. Miller, Case School of 

 Applied Science, Cleveland, Ohio. 



On December 31 the retiring vice-presi- 

 dent. Professor W. F. Magie, of Princeton 

 University, gave a most interesting address 

 on 'The Partition of Energy'; this address 

 was printed in full in Science for Feb- 

 ruary 2, 1906. 



Because of mutual interest in the papers 

 offered in Sections B and D, and because 

 the programs were short, two joint sessions 

 of these sections were held. The program 

 of papers presented is given below, with 

 abstracts of all but one of those belonging to 

 Section B ; the abstracts of the other papers 

 will be given in the report of the secretary 

 of Section D. There was ample time for 

 full discussion of the papers, and advantage 

 was taken of this opportunity, adding much 

 to the enjoyment of those attending. 



Although the attendance was small 

 (there were about thirty-five present at 

 each meeting), yet the quality of the meet- 

 ings in every respect was quite up to the 

 average, and all were unanimous in ex- 

 pressing the opinion that the sessions had 

 been both profitable and enjoyable. Ex- 

 cursions to the pumping and drainage sta- 

 tions, to a sugar plantation and mill and 

 to a sugar refinery, as well as the miscel- 

 laneous attractions peculiar to New Orleans 

 as a city, were greatly enjoyed by those in 

 attendance.
