No. 458.] PARTHENOGENESIS. ; 75 
results connected with the questions of individuality of chromo- 
somes, determination of sex and variation. These are the prob- 
lems to which my own study of parthenogenesis has naturally 
led me and to which I am now seeking solutions in experiments. 
In this way parthenogenesis, an important problem in itself, 
becomes at the same time a method for the study of other and 
greater problems.
