THE FORTY-FIRST GENERAL MEETING OF 

 THE AMERICAN CHEMICAL SOCIETY 



The forty-first general meeting of the Ameri- 

 can Chemical Society was held in Boston in con- 

 nection with the annual winter meeting of the 

 American Association for the Advancement of 

 Science, December 28-31, 1909. Nearly 600 chem- 

 ists were present, making this the largest meet- 

 ing ever held by the society. 



On Tuesday, December 28, excursions were 

 made to the breweries of Massachusetts Brewer-
