of isotopes," (by R. S. Mulliten, both of the 

 Univereity of Chicago. In addition a number 

 of other topics, not yet fuMy decided upon, 

 will be discussed by noted chemists. 



At the symposium on photochemistry and 

 plant physiology to be held Thursday, Decem- 

 ber 28, at 2 p. m., H. A. Spoehr, of :the Desert 

 Laboratory, will discuss "Photosynthesis," S. 

 E. Sheppard will speak on "Photochemical re- 

 actions," and a third speaker will present the 

 subject "Caribohydrate metabolism." 



The address of the ratiring vice-president 

 and chairman of 'Section C will be u,pon the 

 subject "The nuclei of atoms and the general 

 sj'Sitem of isotopes." 



It is expected that one or two of the ses- 

 sions will be provided with a program by 

 nearby sections of the American Chemical So- 

 ciety as follows: the Nontheastern, the New 

 York, the Eastern New York, the Cornell, the 

 New Haven, the Philadelphia, the Washington, 

 ajnd the Ddlaware sections. 



Speakers have been invited to present papers 

 on atomic structui-e, the deotron theory of 

 valence, the nature of metals, 'the work of 

 various great laboraitories, and various other 

 topics of interest to professional chemists. It 

 should be noted that no specific invitations 

 have been sent out for papers on the research 

 work of individuals, but it is hoped that the 

 chemists of the United States and Canada will 

 respond in considerable numbers to the general 

 invitation given in the present notice. The 

 titles of such papers should be sent as soon 

 as ]3ossaMe either to the retiring chairman, 

 Pi-ofessor W. D. Harkins, of the University of 

 Chicago, ito the secretary of the Northeastern 

 Section of the American Chemical Society, 

 Professor E. B. MUlard, of the Massachusetts 

 Institute of Teichnology, Cambridge, Mass., or 

 to the vice-president and chairman, Professor 

 W. Lash Mailer, of the University of Toronto.
