THE PRESENT AND FUTURE OF THE 

 AMERICAN CHEMICAL SOCIETY^ 



In view of the far-reaching changes in 

 our society that are to inaugurate the new 

 year now at hand, it seems to me that no 

 more fitting subject for an address on this 

 occasion could be chosen than one which 

 should present to our members a statement 

 of its present condition, the reasons for the 

 changes undertaken, the importance of 

 these changes to all the chemists of North 

 America, and the need of the loyal support 

 of our present membership at the start in 

 securing the structure of the greater edifice 

 upon a firm and enduring foundation, so 

 that a powerful organization may develop 

 for building up the profession — an organ- 

 ization that shall be fully worthy of what 

 may become, as has been predicted, the 

 future stronghold of chemistry. This 

 presentation seems specially called for at 

 this moment, since the existing situation 

 and what it is hoped to accomplish by the 

 proposed changes are not fully known to a 

 large proportion of our members, particu- 

 larly that portion that is remote from the 

 larger industrial and educational centers 

 and unattached to our local sections. And 

 ' Address of the president of the American 

 Chemical Society, New York meeting, December, 

 1906.
