 ume 51, page 366, 1920, and volume 52, page 304, 1920; 

 Journal of Pharmacology and Experimental Therapeutics, 

 volume 16, page 71, 1920, and volume 17, page 227, 1921 ; 

 and the review by Stewart, "Adrenal Insufficiency" (En-

 Eussell: Soil Conditions and Plant Growth (Longmans, 

 Green & Co., London) ; E. W. Thatcher: The Chemistry 

 of Plant Life (McGraw-Hill, New York).
