OUTSTANDING WORK AND WORKERS 117 



3. Ivan Petrovich Pavlov, whose work as discussed in 

 his The Work of the Digestive Glands (English Transla- 

 tion, 1902) and his researches on cerebral activity and the 

 theory of reflexes brought him the Nobel Prize in medi- 

 cine for 1904. For a good account of his work see M. 

 Dontchef-Dezeuse Ulmage et Reflexes Conditionals dans 

 les Travaux de Pavlov (1914). 



4. Serge Voronoff, whose work on gland grafting has 

 made him, together with Eugen Steinach, one of the out- 

 standing leaders in this field of research. 



5. Besredka and (6) Plotnikow should be mentioned 

 for their work in what may be termed biological medicine. 



Scandinavia 

 Norway 



The Norwegians consider the founding of the series 

 Neue Studien iiber die Reifung der Geschlechtszellen as 

 an outstanding movement. This series is probably the most 

 important of all their biological publications. 



The great names of Norway are : 



1. K. E. Schreiner and his wife (2) Mrs. A. Schreiner, 

 for their work on the maturation of germ cells, a work 

 which definitely settled the question as to the conjuga- 

 tion and reduction of chromosomes, thus rendering a safe 

 basis for the modern cytological study of the problems 

 of heredity. 



3. H. H. Gran, whose Das Plankton des Norwegischen 

 Nordmeeres is without question the very foundation of 

 modern marine planktonology.
