and tall and dwarf stems. Mendel demonstrated that all these 

 differential characters truly segregated after crossing. 



Düring the last few years, many experimenter s, in many 

 lands, have applied the Mendelian principles to many kinds of 

 plants and animals, including Man himself. These experiments 

 have yielded a heavy harvest of facts which fully confirm Men- 

 del's original conceptions of the nature of heredity. 



In illustration of this, a list of characters in plants, animals 

 and Man, which have been found to be subject to MendePs 

 law of segregation, is given below, together with the names of 

 the experimenters and observers concerned in their determination. 

 This list, though fairly comprehensive, is by no means complete, 

 and new characters are being added almost every day. 1 ) 



1 ) In compiliiig this list of Mendelian characters no attempt has 

 been made to detail the germinal factors concerned in the formation of 

 the visible characters noted in the list. In certain cases, therefore, characters 

 included may be merely different reactions of the same germinal factors, 

 while others may be dne to various combinations of unit-factors.
