 Medium nucleated non-nucleated 



part part 



It v/ill be noted that in some cases the non-nucleated 

 fragments lived as long as those which contained nuclei. 

 In fact, by cutting the ameba in such a way that the piece 

 containing the nucleus was smaller than the piece which 

 lacked it, the non-nucleated cell could be made to outlive 

 the nucleated one. Thus ten amebas were divided in such 

 a way that the nucleated piece was from one-half to one- 

 fourth the size of the other. The results are tabulated 

 below :
