On Tuesday evening, October 25, visiting 

 members were guests at a dinner entertain- 

 ment given by the Eoeliester Section of the 

 Society. 



The very well conducted trips through the 

 Eeseareh Laboratories of the Eastman Kodak 

 Company and the glass plant, optical shops 

 and observatory of Bausch and Lomb were 

 also much appreciated by the visiting mem- 

 bers. 



The Rochester Section was given a hearty 



vote of thanks for its hospitality and the 

 many courtesies extended during this very 

 successful meeting. 



Forty new members were elected. The 

 membership is now about three hundred. 



The Society's intention to cultivate actively 

 the field of physiological optics was indicated 

 by the following resolution, adopted October 

 26, 1921: 



Whereas the Optical Society of America is de- 

 voted to the science of optics, pure and applied, a, 

 subdivision of which is the subject of Physiological 

 Optics, with the several contributory sciences of 

 physiology, psychology, physics and chemistry, rep- 

 resentatives of which sciences have at the present 

 time no common meeting ground for the discussion 

 of problems of vision of mutual interest and 



Whereas, the National Research Council, through 

 its Committee on Physiological Optics, has recom- 

 mended to the Optical Society of America the tak- 

 ing of such steps as may be necessary to further 

 and encourage cooperative efforts in research in 

 vision and allied phenomena, therefore be it 



[Resolved that the Optical Society of America 

 does hereby signify its intention of devoting one or 

 more sessions of each annual meeting to papers on 

 Physiological Optics and other appropriate subjects 

 related to vision, and 



Eesolved that there be and hereby is established 

 by the Society a Standing Committee of three, ih* 

 duty of which shall be 



(1) To prepare the program of the sessions on. 

 Vision, 



(2) To coordinate the work of the Society in this 

 field with the work of other Societies and 



(3) To recommend, from time to time, such 

 further steps as may be deemed effective in eneottr- 

 aging research in Physiological Optics and allied 

 problems. And 



Eesolved further that the Optical Society, through 

 its Committee on Physiological Optics, shall invite 

 aU those interested in research on Vision and allied 

 fields to participate actively in these sessions. 



The next meeting will be held at the 

 National Bureau of Standards in Washing- 

 ton in the latter part of October, 1922. It is 

 tentatively planned to hold an exhibition of 

 optical instruments in connection with this 

 meeting.
