NOTICE. 



"TiT"^7'E are preparing a list of Professional Scientists, and of all those engaged in scientific investiga- 

 tor tions in the United States We ask the co-operation of our subscribers and the heads of 

 Universities and Colleges, by forwarding to us lists of Scientific men connected with such institutions. 



We invite all engaged in original research, whether professionals or amateurs, to forward their names 

 and addresses for registration, giving their names and style in full, and the particular line of research followed. 



We desire that the list of Physicists shall be very complete as we understand that such a list does not 

 exist, even at Washington. 



We guarantee to forward all names and addresses received by us to the Smithsonian Institute, Washing- 

 ton, as we understand from the Secretary that such a course would be acceptable. 



Compliance with this request will result in many conveniences to those concerned, as when the lists 



are analytically arranged, those desirous of communicating with their fellow workers will have facilities for so 



doing, and papers and notices can be distributed without delay. Scientific men, at present dispersed over 



a wide territory, will thus be united, so as to make co-operation possible when occasion requires.
