position products thus incidentally gained in this study of the analytical 

 methods has much value apart from its application to the analysis of other 

 proteins and is to be considered a part of an extensive investigation of the 

 proteins of this important seed which we have already entered upon. 



The results of the work above described have been published in the Ameri- 

 can Journal of Physiology, 1910, xxvi, pp. 212-228, 295-304, and 305-328; 

 420-425. 



An extensive study of the proteins of the hemp seed has been made which 

 is now approaching completion. This is designed to give information con- 

 cerning the nature and proportion of all of the different proteins of this seed 

 and a better knowledge of their properties. It is expected that this work will 

 yield results of general application for the better isolation and preparation of 

 seed proteins than has heretofore been possible and also shed light on some 

 of those minor changes which proteins tmdergo and about which little is at 

 present known. Some further work is required to make the data thus far 

 accumulated available for publication. 



During the past year extensive feeding experiments have been undertaken 

 in cooperation with Prof. Lafayette B. Mendel, of Yale University, under a 

 grant from the Adams fund. The purpose of this work is to study the rela- 

 tive nutritive value of the more important food proteins. In connection with 

 this investigation much work has been done under this grant in preparing 

 large quantities of proteins for feeding purposes and in obtaining more defi- 

 nite knowledge of the properties of some of these proteins which appeared 

 to be of importance in connection with their food value. Valuable data have 

 already been obtained and a part of these have been discussed in a paper 

 which is now nearly ready for publication. 



An extensive study of the anaphylaxis reaction has been begun in coopera- 

 tion with Prof. H. Gideon Wells, of the University of Chicago, who has 

 already conducted several hundred experiments on animals with very pure 

 preparations of proteins which we have prepared for him. The results of 

 this study are now ready for publication.

Case, E. C, University of Michigan, Ann Arbor, Michigan. Grants Nos. 559 

 and 611. Continuation of the work on the Permian reptiles and am- 

 phibia of North America. (For previous reports see Year Books Nos. 

 2, 4, and 8.) $3,200 



Professor Case has completed the preliminary manuscript of two mono- 

 graphs, one on the Cotylosauria and Pareiasauria of North America and one 

 on the Amphibia and Pisces of the Permian of North America. These will 

 average about 275 pages each and will be accompanied by about 30 plates each 

 and numerous text figures. The manuscripts are the result of studies in 

 American museums. Last summer Professor Case studied related forms in
