MECHANICAL SEPARATION OF 

 CELLULAR COMPONENTS 



"When one sets out upon the serious and difficult 

 business of wresting from the universe more knowl- 

 edge of its character and qualities, his efforts must 

 all meet with failure unless he can move with perfect 

 freedom toward the truth wherever the path may 

 lead. No authority must stay him there; no tradition 

 perplex him; no dogma, no prejudice, no vested 

 interest prevent the thorough exploration of every 

 promising avenue he sees. From its beginning, science 

 has struggled to be free from all such man-made 

 bondage." 



Edmund W. Sinnott 

 in Science and the Education of Free Men, American 

 Scientist 32: 210 (1944).
