METABOLISM 279 



have already been summarized in the section on blockage of 

 regeneration (p. 132). 



Speaking generally, metabolism studies on Stentor may be 

 fruitful in two directions. Demonstration of metabolic similarities 

 between these and other animals would prove the appropriateness 

 of using the special advantages of Stentor in pursuing problems of 

 "universal biochemistry". In addition, stentors may reveal or 

 provide initial discoveries of features of metabolism hitherto 

 unknown.
