NOTES. 499 



G. W. Hoover, associate referee on medicated soft drinks, reported satis- 

 factory results in cooperative worli in the determination of the constituents 

 caffein, cocain, phosphoric acid, and total solids. W. O. Emery, associate 

 referee on synthetic drug products, reported that in analyses of headache 

 tablets a method had been devised for the estimation of cafCein, acetanilid, 

 quinin, and morphin in the same preparation. Aspirin was also studied in 

 regard to melting point, either alone or in admixture with salicylic acid. 

 Salol was estimated satisfactorily with a standardized bromin solution. A. G. 

 Murray reported cooperative work on the estimation of nitroglycerin in medici- 

 nal tablets, and H. E. Buchbinder on similar work with the Eaton method for 

 morphin. 



At the suggestion of W. D. Bigelow, a committee was appointed to edit a new 

 issue of the official methods of analysis. Resolutions were adopted in memory 

 of the late Director M. A. Scovell, of the Kentucky Station, and Prof. H. A. 

 Weber, of Ohio State University. 



The papers read during the session were as follows: A Proposed Modifica- 

 tion of the Official Method for Determining Humus, by O. C. Smith ; Applica- 

 tion of the Ammonium Carbonate Method for the Determination of Humus to 

 Hawaiian Soils, J. B. Rather ; Note on the Analysis and Valuation of Maple 

 Sugar, A. H. Bryan ; A Proposed Method for the Determination of Tartaric
