The Nutrition of the Non-Nucleated Cell. 



Since, as v/aa shovm above, ^■ilucose prolongs the life 

 of amebas, and apparently acts a3 a food, it would be 

 interesting to know whether it has a similar effect upon 

 the cell from which the nucleus has been removed. 

 To determine this, the nucleus was removed from a number 

 of amebas, care being taken to remov^e as little protoplasm 

 as possible. Under favorable circumstances it is possible 

 to cut the nucleus from the cell vnlthout removing more 

 than one- tenth of the protoolasm. Some of the amebas were 

 now transferred to water, while others of equal size were 

 kept in glucose solutions. The usual precautions were 

 taken to prevent the development of bacteria.
