The arrangements for the dinner were in charge of a committee 

 consisting of Dr. Walter H. Eddy, chairman, Prof. Paul E. Howe 

 and Dr. Alfred P. Lothrop. 



Fourteenth meeting. Abstracts of the Communications which 

 constituted the scientific proceedings of the meeting on Dec. 5, 1913, 

 are given at page 303. 



Ostwald lectures. At the Suggestion of the Exec. Commit. of 

 the Biochem. Assoc, Columbia Univ. invited Dr. Wolf gang Ost- 

 wald, Privatdozent at the Univ. of Leipzig, editor of the Kolloid- 

 Zeitschrift and Kolloidchemische Beihefte, to deliver, at Columbia 

 Univ., the series of lectures indicated below : 



MoNDAY, Jan. 19, Havemeyer Hall: What are colloids?; elements 

 of qualitative colloid analysis ; formation and preparation of colloids. 



TuESDAY, Jan. 20, Havemeyer Hall: Mechanical, optical, electrical, 

 and chemical properties of substances in the colloid state ; Classification 

 of the colloids. 



Wednesday, Jan. 21, Coli, of Physicians and Surgeons: Changes in 

 the colloid State ; internal changes of state, swelling, setting, syneresis, 

 adsorption, coagulation, peptisation. 



Thursday, Jan. 22, Havemeyer Hall: Scientific applications of col- 

 loid chemistry. 



Friday, Jan. 23, Havemeyer Hall: Technical applications of colloid 

 chemistry. 



Each of the lectures was attended by an unusually large and 

 attentive audience. 



A similar series of lectures was delivered by Dr. Ostwald at each 

 of the following institutions : Univ. of Cincinnati, Jan. 5-1 1 ; Univ. 

 of 111. (Urbana), Jan. 12-17; Johns Hopkins Univ., Jan. 26-31. 



Before returning to Leipzig, Dr. Ostwald will probably deliver

 and Kansas, at McGill Univ., and before chemical societies in 

 Washington and Indianapolis. 



Fifteenth meeting. Ostwald smoker and reception. The 

 members of the Assoc. had the privilege of meeting Dr. Ostwald, as 

 their guest, at a smoker in the library of the Coli, of Phys. and Surg., 

 on the evening of Jan. 23. Dr. Ostwald addressed the Assoc. in- 

 formally, after Dr. Gies had expressed, for the members, the pleas-
