Altho the amebas kept in glucose lived sonewhat longer 

 than the controls, the effect was not very striking, 

 oince there are great differences between different amebas, 

 even when selected from the same culture, a somewhat more 

 satisfactory experiment was performed as follo'."s: The 

 nucleus was removed from a numbi r of amebas, and then the 

 amebas were divided in half. One half was kept in water, 

 as a control, while the other half was kept in a solution

The non-nucleated cells live longer in glucose solu- 

 tions, and prob-ibly use it as a food. This is in agree- 

 ment with the work of Rous and Turner (1^15), who used 

 glucose for the preservation of the non-nucleated red
