At the. Commencement of Washington University, June 10, 

 1920, the degree of Doctor of Philosophy was conferred upon 

 W. H. Chambers, with a thesis on "Studies in the Physiology 

 of the Fungi. XI. Bacterial Inhibition by Metabolic Prod- 

 ucts"; Takashi Matsumoto, with a thesis on "Physiological 

 Specialization in Rhizoctonia Solani.Kuhif ; and Joanne L. 

 Karrer, with a thesis on "Amylase Production and Activity in 

 Fungi as Affected by Hydrogen Ion Concentration." The 

 degree of Master of Arts was conferred upon B. B. Payson, 

 with a thesis on "A Monograph of the Genus Lesquerella. " 



Publications and Papers. — The various scientific articles 

 which have been published during the year whether in the 

 Annals or in other journals are included by title in the list 

 below. Several graduate theses as well as staff investigations 

 remain unpublished, and much of this material will be used 

 in the next few numbers of the Annals. 



In the graduate laboratory particular attention has been 

 paid to various aspects of the relation between hydrogen-ion 

 concentration and certain life phenomena. The mineral and 

 organic food nutrition of higher plants continues to receive 

 considerable attention. Consistent efforts are also being made 

 to throw light upon the causal relations in mosaic diseases.
