attention being given not only to the behavior of each proximate com- 

 pound with re agents, but also to its elementary composition, molecular 

 constitution, changes under the action of ferments, digestibility, and 

 potential energy. The importance of collateral studies from the stand- 

 I)oint of vegetable physiolog}" and histology was urged, and the neces 

 sity of classifications of the compounds, based upon their actual proper- 

 ties, and of improved methods for separation, quantitative estimation, 

 and estimates of nutritive values, was dwelt upon. It was suggested 

 that chemists in educational and other institutions, as well as in the 

 experiment stations, might cooperate; that pecuniary aid for such re- 

 searches should be sought; and that the results would be valuable in 

 the highest degree as contributions to science, as well as for their prac- 

 tical usefulness. 



The report of Professor Eising on fermented liquors was accepted 

 without discussion, and the recommendations of last year continued. 



In addition to the reports above mentioned several papers were read. 

 Among these were : Notes on Occurrence and Quantitative Estimation 

 of Peutaglucoses in Fodders and Feeding Stuffs, by Dr. W. E. Stone, 

 the tenor of which is well indicated by the title; Determination of 

 Phosphoric Acid in Cotton-Seed Meal, by F. B. Dancy, the paper tend- 

 ing to show that the last two official methods of the past year were 

 wholly inadequate in case of this material ; Difl^rences iu the Determi- 

 nation of Reverted Phosphoric Acid, by Dr. Charles Gibson, of Chicago. 

 Prof. H. A. Huston spoke on variations in the determination of citrate- 

 soluble phosphoric acid caused by different factors, illustrating his 

 remarks by means of charts. 



As recommended by the executive committee, the chapter of cattle 

 foods was divided under two heads, materials high in carbohydrates, 

 and those low in these constituents ; and a reporter was appointed for 

 ash and soil analysis. A committee, consisting of Messrs. Wiley, At- 

 water, and Robinson, was appointed to inquire into the desirability and 

 feasibility of establishing a chemical laboratory at the Columbian Ex- 

 position to be held at Chicago in 1893, and requested to report at the 

 next meeting of the Association. 



A committee, consisting of Messrs, Wiley, Stubbs, Frear, Caldwell, 

 and Nicholson, was appointed to confer with committees from the 

 American and the Washington Chemical Societies, and other chemical 

 bodies, regarding the formation of a National Chemical Society. 



The officers and reporters elected for the ensuing year are as follows : 

 President, G. C. Caldwell; vice-president, N. T. Lupton; secretary, 

 H. W. Wiley; executive committee, R. C. Kedzie and E. B. Voorhees; 

 reporters, on nitrogcu, William Frear; on phosphoric acid, H. A. Hus- 

 ton; on potash, H. B, Battle; on ash and soil, R. C. Kedzie; on dairy 

 products, W. W. Cooke ; on foods and feeding stuffs high in carbohy- 

 drates, A. E. Kuorr; on foods and feeding stuffs low in carbohydrates, C. 

 D. Woods ; on sugar, W. C. Stubbs ; on fermented liquors, W. B, Rising;,
