AMERICAN ASSOCIATION FOR THE AD- 

 VANCEMENT OF SCIENCE. 

 SECTION B— PHYSICS. 



At the summer meeting of the American 

 Association for the Advancement of Sci- 

 ence, held in Ithaca, N. Y., from June 28 

 to July 3, 1906, Section B met in joint ses- 

 sions with the American Physical Society. 

 The section was, in an especial sense, the 

 guest of the department of physics of Cor- 

 nell University, for on this occasion there 

 occurred the formal dedication of the new 

 Rockefeller Hall of Physics. At the dedi- 

 cation exercises there were addresses by 

 President Schurman, Professor E. L. 

 Nichols, Dr. Elihu Thomson, Professor W. 

 H. Welch and by Professor W. A. Anthony 

 (read by Professor Merritt, in Professor 

 Anthony's absence). After the addresses, 

 the magnificent laboratory was opened for 

 inspection. 



On account of the interest in the new 

 laboratory, no doubt, the attendance at the 

 regular sessions was large, there being 

 about seventy present. The president of 

 the American Physical Society being ab- 

 sent, the vice-president of Section B, Pro- 

 fessor AV. C. Sabine, presided at all the 

 sessions. A very interesting joint program 

 of twenty-seven papers was presented. 

 Abstracts and titles are given below. Be- 

 sides the features already mentioned, sev- 

 eral receptions and excursions, and the 

 general hospitality of Cornell University 

 added greatly to the enjoyment of the 

 meetings. This summer meeting was very 

 successful.
