SECTION C PHYSICAL CHEMISTRY 



(Hall 16, September 22, 10 a. TO.) 



CHAIRMAN: PROFESSOR WILDER D. BANCROFT, Cornell University. 

 SPEAKERS: PROFESSOR J. H. VAN 'T HOFF, University of Berlin. 



PROFESSOR ARTHUR A. NOTES, Massachusetts Institute of Tech- 

 nology. 

 SECRETARY: MR. W. R. WHITNEY, Schenectady, N. Y. 



THE Chairman of the Section of Physical Chemistry was Professor 

 Wilder D. Bancroft, of Cornell University, who opened the work of 

 the Section with the following remarks : 



"Twenty years ago physical chemistry was not recognized as a 

 subdivision of chemistry. To-day nearly every larger university in 

 this country has a chair of physical chemistry, and we have our regu- 

 lar place on the Programme along with inorganic and organic chem- 

 istry. In fact, Professor Clarke in his address rather implied that 

 physical chemistry now dominates the whole of chemistry. Certain 

 it is that physical chemists are much in demand at this Congress and 

 that to hear them all you must go to many Sections. Van 't Hoff is 

 to speak to you here this morning, Arrhenius delivers an address the 

 next hour before the Section of Geophysics, Ostwald is to speak this 

 afternoon as a philosopher, while Sir William Ramsay was one of the 

 chief speakers yesterday before the Section of Inorganic Chemistry. 



"In addition to the two longer addresses, our Programme includes 

 shorter papers on the chemical affinity between solvent and solute, 

 on the chemistry of liquid ammonia, on transference in acetic acid 

 solutions, and on the application of physical chemistry to agriculture. 

 The first address is on the history of physical chemistry by the man 

 who made that history possible, Professor van 't Hoff of Berlin."
