DOCTORATES IN BIOLOGICAL CHEMISTRY 



Conferred by American Universities, 1911-12 



The names of recent recipients of the Ph.D. degree in biochem- 

 ical science, with the subjects of the dissertations, are arranged 

 below in university groups '} 



Brown University. — William Ward Browne: Acid production 

 by the Bacillus coli group. 



Columbia University.^ — David 'Alperin: Contribution to the 

 knowledge of nucleoprotein metaboHsm, with special reference to 

 uricolysis and to the properties of uricase. — Louis Edward Bisch: 

 Biochemical studies of protagon and mucoid. — Jacob J. Bronfen- 

 brenner: A biochemical study of the phenomena known as comple- 

 ment Splitting. — Alexander Oscar Gettler: The balance of acid- 

 forming and base-forming Clements in foods, and its relation to 

 ammonia metabolism. — Marston Lovell Hamlin: ( i ) The prepara- 

 tion of two derivatives of glucosamine; (2) Spigeline, an alkaloid 

 of Spigelia marilandica; (3) Derivatives of 4-hydroxy-5-nitro- 

 quinazoline. — Raleigh Frederick Hare: A study of the chemistry 

 of the carbohydrates of the prickly pear and its fruits. — Max Kahn: 

 Biochemical studies of sulfocyanates. — John Leonard Kantor: A 

 biochemical test for free acid. — Chester Arthur Mathewson: A 

 study of some of the more important biochemical tests. — Emily 

 Cromwell Seaman: Biochemical studies of the effects of beryllium 

 Sulfate. — Harald Edzvard Woodward: A study of surface tension

^ In a few cases awards of the degree in organic chemistry (e. g., at Yale 

 University), on subjects of special biochemical significance, are included. 



^Additional Information regarding the Columbia doctors {and masters) in 

 biological chemistry, is given on page 575, where may also be found the names of 

 successful Ph.D. candidates in botany, zoology and organic chemistry whose 

 minor work was done, in part, in the Columbia department of biological 

 chemistry.
