262 REPORTS ON INVESTIGATIONS AND PROJECTS. 



Grant No. 263 ($41,000). — Under this grant work has been in 

 progress only a few months, and, as it has been impossible until 

 recently to secure the full quota of assistants, the progress made has 

 not been so great as it will be during the remainder of the year. A 

 series of quantitative determinations of glutaminic acid has been made 

 in over twenty of my pure preparations of as many different vegetable 

 proteins, and the results of this work are practically ready for pub- 

 lication. The proportion of arginine, histidine, and lysine in several 

 of these vegetable proteins has been determined, and it is my inten- 

 tion in the immediate future to make similar determinations in a large 

 number of other proteins. 



A great deal of time and labor has also been devoted to making 

 large quantities of the purest possible preparations of the various 

 vegetable proteins studied during the past years in this laboratory, 

 with the intention of determining the proportion of the various decom- 

 position products which they yield on boiling with strong acids. The 

 purpose of this work is to obtain information respecting the structural 

 differences between these various proteins, with a view to determine 

 the chemical relations of these substances to one another, as well as 

 their nutritive and physiological relations. 



Reichert, Edward T., and Brown, Amos P., University of Pennsyl- 

 vania, Philadelphia, Pennsylvania. Grant No. 188. Research 

 on the crystallography of hemoglobins. (For first report see Year 

 Book No. 3, p. 134.) $1,000. 



Drs. Reichert and Brown state that their research has progressed 



satisfactorily. A report upon the result of their investigations may 



be expected later.
