THE CELL 87 



throughout the metazoa from the coelenterates up to 

 man." 



The reader will see from this statement, Fig. (8), by 

 Prof. Wilson, that it appears clearly the male cell is a 

 structure built up and composed of a multitude of still 

 smaller primordial beings ; that the central part of the cell, 

 the nucleus, contains those who are skilled and under- 

 stand the work that has been done and is to be done in the 

 future, and that the centrosome is the directing center 

 and general manager whose duty it is to guide the actions 

 of all ; that the main body of the cell which is called cyto- 

 plasm, contains the common laborers and servants, who 

 work and act from instructions and orders given by -the 

 skilled workers or centrosome. We see that the male cell 

 in this race to find the female cell employs the entire force 

 of common laborers in the body of the cell to push and 

 carry him to the desired place. Consider for a moment this 

 preparation of thousands who are willing to prepare for 

 this race, where all but one must fail to reach the goal, 

 and all but one must perish. However, it is a fair race, 

 based on the law of evolution, that the best man in a 

 struggle for existence will win. In this act, as in all other 

 schemes in nature, where there is intelligence there is 

 authority, design, purpose, wisdom and victory. Here 

 it seems that microscopic and mysterious beings we call 

 the centrosomes are able to direct all the other micro- 

 scopic beings in the cell to subjugate and organize mat- 

 ter, so as to create for themselves an existence on the 

 planet. It appears that the centrosome is the real source 

 of will and intelligence in the cell, just as the brain cells 

 are the source of intelligence in animals and man. 



This male cell of animals is so very similar in shape and 

 actions to male cells or spermatozoons of plants and in- 

 sects, and also cells living a single and separate life in
