•the American Chemical Society, fittingly re- 

 sponded. The society then held a general meet- 

 ing, at which the following papers were pre- 

 sented : 



' ' The Chemical Problems of an Active Volcano ' ' 

 (illustrated), by Arthur L. Day. 



' ' The Chemical Fitness of the World for Life, ' ' 

 "by L. J. Henderson. 



"Flame Reactions," by W. D. Bancroft. 



' ' Chemical Reactions at Low Pressures, ' ' by 

 Irving Langmuir. 



At one o'clock the society adjourned for an 

 excursion to the Filtration Plant of the Cin- 

 cinnati Water Works, optional excursions being 

 available to the following plants: 



Andrews Steel Co., Wiedemann Brewing Co., 

 •Old "76" Distilling Co., Frank Tea and Spice 

 Co., Heekin Spice Co., Icy-Hot Bottle Co., Cin- 

 'Cinnati's New City Hospital preceded by car ride 

 through suburbs, the Dolly Varden Chocolate Co., 

 "W. T. Wagners' Sons Mineral Waters. 



In the evening, a complimentary dinner was 

 given to the ladies attending the meeting, followed 

 by a theater party. At eight o'clock, P.M., a 

 complimentary smoker was held at the Hotel 

 ■Sinton, with 550 members and guests present. 

 Mementos were given to all those attending, and 

 the smoker will long be remembered, especially 

 for the interesting and witty entertainment pro- 

 Tided by the local members, and by talent espe- 

 cially engaged for the occasion. 



Divisional meetings were held on Wednesday 

 morning and all day Thursday at the University 

 of Cincinnati, at which 181 papers were pre- 

 sented, a special symposium on the teaching of 

 organic chemistry being also held by that di- 

 "vision. 



Complimentary lunches were furnished on Wed- 

 nesday and Thursday. On Wednesday afternoon 

 the members were taken through the works of the 

 Globe Soap Company and Proctor and Gamble, 

 with the following optional excursions also offered, 

 "W. S. Merrell Chemical Co., Lloyd Library and 

 Museum, Fleischmann Distilling Co., American 

 Diamalt Co., Eagle White Lead Co., National Lead 

 XJo., Lunkenheimer Co. Brass Goods, the Zoolog- 

 ical Gardens. 



On Wednesday evening a symphony concert was 

 given complimentary to the members of the so- 

 ciety, and the immense Emery auditorium was 

 ^filled to hear a concert, under the direction of 

 rErnst Kuhnwald, which has had few superiors in 

 the history of American music. 



On Thursday evening, a banquet was enjoyed 



by the members at the Hotel Sinton, with some 

 300 present. The banquet was unusual in that 

 especially fine music was furnished by soloists. 

 A decoration particularly worthy of note was an 

 immense American Chemical Society pin in blue 

 and gold flowers. 



On Friday a special train complimentary to the 

 members of the society took them and their guests 

 to Dayton to visit the works of the National Cash 

 Register Company, where lunch was served to all 

 of those attending, after which the train pro- 

 ceeded to the works of the American Rolling Mills, 

 at Middletown, and from there to Cincinnati. 

 This day's excursion was particularly enjoyed 

 and the works visited were among the most in- 

 teresting ever opened to the members of the so- 

 ciety. 



The meeting closed with the arrival of- the mem- 

 bers in Cincinnati, and will always be remem- 

 bered by those present. The members and offi- 

 cers of the Cincinnati section made every effort 

 to insure the comfort and entertainment of their 

 guests, and their hearty good will will never be 

 forgotten by the recipients of their hospitality. 



Meetings of all of the divisions of the society, 

 as well as the India Rubber Section and the Water, 

 Sanitation and Sewage Section were held. De- 

 tails will appear in the published program, as 

 above stated. 



The meeting was the largest spring meeting 

 ever held in the history of the society, 658 mem- 

 bers and guests being present. 



The following are abstracts of the papers pre- 

 sented before the various divisions so far as they 

 could be procured:

 Address. Floyd W. Robinson, chairman. 

 Standards of Food and Drug Chemists: Edward

The Determination of Mixed Carbohydrates in 

 Infant Foods: T. M. Rector and E. B. Wet- 



TENGEL. 



In preparations containing mixtures of sucrose, 

 maltose, lactose and dextrine, the sucrose is deter- 

 mined by loss of rotation after inversion with in- 

 vertase. The dextrine is determined by loss of 

 polarization after precipitation with lead acetate 

 and ammonia. The combined polarization of the 

 sucrose and dextrine is subtracted from the total 

 polarization, giving the polarization of the mal-
