Poland 



Although she did her work in France, Madame Marie 

 S. Curie (nee Marie Sklodowska) is Polish-born, and was 

 educated in Warsaw. In 1911 she received the Nobel Prize 

 in chemistry for her discovery of radium and polonium. 

 She has two unique distinctions, (1) of being the only 

 woman to be Nobel laureate in any science, and (2) of 

 being the only person of either sex who has received the 

 Nobel Prize in two separate fields of learning — chemistry 

 and physics. 



Russia 



It has been as difficult to get any reliable information 

 about Russian science as it is to get it about Russian 

 politics, but several names are well known throughout 

 the scientific world and should be mentioned here. 



They are : 



1. S. Korschinsky, whose mutation theory is best known 

 to us through the German items appearing at various times 

 in European papers. His "Heterogenesis and Evolution" 

 appeared in Natur Wochenschrijt, Vol. XIV, 1899, and 

 again "Heterogenesis u. Evolution," in Flora, oder Allg. 

 Bot. Zeit. Erganzungsbd. 89, 1901. 



2. Elie Metchnikoff, whose work on immunity in infec- 

 tious diseases and the prolongation of life, made him No- 

 bel laureate in medicine for 1908.
