tids give a substantial basis for the hypothesis that pro- 

 toplasm may be built of minute dividing bodies, which 



form its ultimate structural basis The 



cell is, in Burke's words, an elementary organism, which 

 may by itself perform all the characteristic operations of 

 life, as in the case with a unicellular organism. 

 Even when the cell is but a constituent unit of a higher 

 grade or organization as in multicellular forms, it is no 

 less truly an organism and in a measure leads an inde- 

 pendent life, even though its functions be restricted and 

 subordinated to the common life." 



These statements by Prof. Wilson show that the cell, 

 whether living his separate life in the water or other 

 places, or acting as one of the units that make up the 

 individual animal or plant, is an animal that has the 

 power to perform all the functions of life. They also 

 show clearly that all the different and separate special 

 organs of the cell are crowds or colonies of still smaller 

 cells or units that lead individual and separate lives 

 within the body of the cell ; that they feed and multiply 

 within the cell in the same manner that the cell lives a 

 separate individual life within the body of plants and 

 animals. It shows that when the cell divides it is simply 

 a division of a crowd of specifically skilled workers or 

 beings and that when the cell multiplies by division each 

 colony of specifically skilled workers in the centrosome 

 and nucleus divides in two and each half then multiplies 

 until it again reaches its original number and size when 

 it is ready to divide again. The most wonderful thing is 

 the centrosome or the directing center of the cell, which 

 when the cell divides has charge of the work of looking 

 after and seeing that the different crowds of specifically 

 skilled workers are equally divided. 



The centrosome seems to be the center of intelligence
