CAUSE OF HEREDITY 277 



ferent cells during- the process of development, as as- 

 sumed by the Roux-Weisman theory. If it were so, this 

 selection of different entities must begin at the first cell 

 division, but it has been proved by experiment that even 

 when the sixteen cell stage has been reached, each of the 

 sixteen cells possesses within itself the power of produc- 

 ing, not only the tissues, which it would produce under 

 normal conditions were the ovum left to itself to develop, 

 but when separated from its fellows, also all of those tis- 

 sues that would have been produced under normal con- 

 ditions by the other fifteen cells." 



This also shows that in division each one is able to pass 

 on to the next one in some way the record of past events 

 and experiences, which evidently is what we call the 

 power of memory. In what manner the record is taken 

 and kept we do not know. We can clearly see that they 

 are very strict and careful in seeing to it in division that 

 each one gets his equal half of the entire colony of pri- 

 mordial beings which make up the cell. It is evident also 

 that the force in the cell is kept in duplicate. We do not 

 understand the phenomenon of memory nor is it neces- 

 sary in order to understand the cause of heredity and de- 

 velopment. We know memory to be a fact, because the 

 cells in our head can remember what took place in our 

 childhood fifty or eighty years back. We know that 

 there cannot be such a thing as intelligence without mem- 

 ory. We know that all animals, including man, reason 

 and act from past experiences. 



The cell is an animal. From the facts based upon what 

 we see the cell do in the act of division, we are forced to 

 the conclusion that every cell is able to remember not 

 only what he has experienced during- his own life but also 

 what took place in the immediate generation before him. 

 Another experiment also goes to show that it is not
