THE SAN FRANCISCO MEETING OF TEE 

 AMERICAN PHYSICAL SOCIETY 



The American Physical Society will unite 

 with Section B of the American Association 

 for the Advancement of Science in a joint 

 meeting to be held at San Francisco Au^st 

 2 to 7, 1915. 



The program of the meeting is in special 

 charge of the Pacific Coast Committee of the 

 American Association for the Advancement 

 of Science and will differ somewhat from that 

 of ordinary meetings. The presentation of 

 the results of individual research in short 

 papers volunteered by their authors will be a 

 minor feature of this meeting, but several 

 sessions will be devoted to a somewhat broader 

 consideration of the larger questions of phys- 

 ics, particularly those which have engaged the 

 attention of Pacific coast workers. At these 

 sessions only papers given on invitation will 

 be presented. One session will probably be 

 devoted to spectroscopy and another to at- 

 mospheric physics, the latter in charge of Pro- 

 fessor W. J. Humphreys. 



On Wednesday, August 4, the society will 

 visit Stanford University and Professor 

 Harris J. Eyan will give demonstrations with 

 high-potential electric currents in the new 

 laboratory especially equipped for such work. 

 The meetings on other days will be held at the 

 University of California at Berkeley. On 

 Friday the ofiicers of the Physical Society will 

 have charge of a session — or two if necessary 

 ■ — at which ordinary research papers will be 

 presented. It is hoped that the western work- 

 ers who do not often have an opportunity to 

 attend our meetings may be conspicuous on 

 this program and their contributions are espe- 

 cially requested. Visiting members from the 

 east are not urged to present many papers, as 

 time will be somewhat limited. 



Physicists are invited to attend the joint 

 sessions of the American Mathematical So- 

 ciety and the American Astronomical Society 

 at Berkeley, Tuesday forenoon, August 3. 

 An address will be given by Professor C. J. 

 Keyser, of Columbia University, New York, 

 on " The Human Significance of Mathe- 

 matics," and by Dr. George E. Plale, of Mt. 



Wilson Solar Observatory, on "'' Recent Prog- 

 ress in the Development of Astronomical Sci- 

 ence." 



An excursion to Lick Observatory has been 

 arranged for Friday, Aug-ust 6, by the Ameri- 

 can Astronomical Society. The observatory 

 may also be visited on any day of the year 

 from 8 A.M. to sunset, and on Saturday even- 

 ings by those arriving before 9 o'clock. Satur- 

 day evening visitors have the privilege of ob- 

 serving the stars with the 36-inch and 12-inch 

 telescopes. The railway station for the Lick 

 Observatory is San Jose. An auto-stage 

 leaves San Jose on six days of the week at 

 8 :30 A.M., stops at Smith Creek Hotel for 

 luncheon and reaches the summit of Mount 

 Hamilton before noon. The stage departs at 

 1 :30 P.M. and reaches San Jose before 4 p.m. 

 The round trip fare for the individual trip by 

 auto-stage is $5. 



The director of the Mount Wilson Solar Ob- 

 servatory extends a cordial invitation to men 

 of science interested in astronomical and 

 physical research to visit the observatory 

 either before or after the San Francisco meet- 

 ing of the association. The shops and labora- 

 tories in Pasadena and the observatory build- 

 ings on Mount Wilson will be open, and all 

 phases of the work in progress can be seen. 

 The Mount Wilson Hotel Company maintains 

 a daily auto-stage service between Pasadena 

 and the summit, where comfortable accommo- 

 dations for the night may be found at the 

 hotel. H time is limited, the round trip from 

 Pasadena can be made in a day. The auto- 

 stage leaves the office of the company (173 E. 

 Colorado Street) at 9:30 A.M., reaching the 

 summit at 11 :45 a.m. On the return trip the 

 stage leaves at 3 p.m., and arrives in Pasa- 

 dena at 4:45 p.m. The round trip fare is $3. 



The director of Congresses of the Panama- 

 Pacific Exposition has organized a special 

 convention news bureau to give due publicity 

 to papers and proceedings of organizations 

 meeting in San Francisco and vicinity. This 

 will include the preparation, in advance of 

 the meeting of articles for the daily press 

 and for magazines, reporting each session for 

 daily press and news agencies and in some
