THE ROCHESTER MEETING OF THE OPTICAL 

 SOCIETY OF AMERICA 



The Optical Society of America will meet 

 in Rochester, N. T., on Monday, Tuesday and 

 Wednesday, October 24, 25, and 26, at the 

 Hotel Rochester. In order to provide the 

 maximum opportunity for social meetings of 

 members and guests, arrangements will be 

 made for society lunches and dinners. 



The regular sessions for the reading of 

 papers will be open to all interested persons. 



Members and others desiring to communi- 

 cate results in optical research are invited to 

 submit titles of papers for the program to the 

 secretary any time before September 25. 

 !N"o arbitrary time limit is set for the presenta- 

 tion of a paper, but each author is requested 

 to estimate carefully the time which will be 

 sufficient to present his paper briefly and in- 

 telligibly, and to submit this estimate with 

 the title. 



Each title must be accompanied by an ab- 

 stract (100 to 200 words). Authors are urged 

 to make every eifort to present the essence of 

 their papers as cogently as possible in these 

 abstracts. It is expected that they will be 

 printed in thy program and in the minutes of 

 the meeting. No titles will be printed to be 

 presented " by title." 



Persons having papers ready for publication 

 which can not be presented at the meeting are 

 invited to submit them to Paul D. Foote, 

 editor. Journal Optical Society of America, 

 Bureau of Standards, Washington, D. C. 



Because of the optical industries in Roches- 

 ter it is expected that this will be a particu- 

 larly interesting meeting. The local com- 

 mittee is arranging for a visit to the Bausch 

 and Lomb Optical Company and the Eastman 

 Kodak Company. 



The National Research Council Committee 

 on Physiological Optics has asked the society 

 to form a section on vision. It is hoped to do 



this at the coming meeting; and, if a suffi- 

 cient number of papers on this subject are 

 submitted, one whole session will be devoted to 

 vision and physiological optics.

 society consult Science for April 1, 1921.

 Mr. Swasey, followed similar ceremonies in

 steel. The Hadfield award was for 1921 and
