CHEMICAL TECHNIQUES 



"By calling attention to the cell I desired to provoke 

 investigators to inquire into the processes within the 

 cell, to define that which happens within these small- 

 est elementary organisms. And it was self-evident that 

 an exact definition could be nothing else than to find 

 the chemical and physical foundations upon which 



vital phenomena and the activity of the cell are 

 based."
