The appended notice is a copy of a circular letter vvhich has been 

 forwarded to various investigators. We heartily commend the pur- 

 poses and plans there stated to the favorable consideration of bio- 

 logical chemists. 



" As a result of the recent meetings of the Biological Section of 

 the American Chemical Society, the question of the Organization of the 

 Section into a Division is to be decided by the Council of the Society 

 at its meeting in December in Washington, If the action is favorable, 

 the Division will presumably be organized at that meeting. Your 

 active interest in the Society and in the Biological Section at its De- 

 cember meeting is earnestly invited. In number of chemists present 

 the meeting promises to stirpass all previous meetings. On Friday 

 afternoon, December 29, the American Society of Biological Chemists 

 will hold a Joint Session with the Biological Section of the American 

 Chemical Society.
