can produce another one like himself when we consider 

 the facts. Every organ in the body as a whole can be 

 trained ; the hand can be trained to do this and that until 

 it remembers just how to do it. For instance in writing, 

 every cell of the hand must remember the different move- 

 ments. You can train the eye, arm or leg by repetition, 

 just as you can the mind or thinking cells. One will 

 learn as well as the other. Memory is a fact. It is a 

 faculty possessed by all the cells. We know by our own 

 experience that our mind is a record of the past. The 

 records of past events and experiences are piling up all 

 the time. The records are there, but the most difficult 

 thing to do sometimes is to find the one we want, and we 

 say we have forgotten. 



It has been proven that cells are always of the same 

 size. In reference to this Wilson states : "Measurement 

 of the cells from the epidermis, kidney, liver, then alimen- 

 tary epithelium and other tissues, shows that they are on 

 the whole as large in dwarfs as in giants, and the same 

 appears to be the case in the plants." In the same man- 

 ner the size of a house or an ant hill has no effect on the 

 size of the individuals that build and occupy it. 



Walker states that it is easy to see how individual char- 

 acters can be transmitted from parent to offspring. He 

 states : "How this happens in the case of the individual 

 character is easy to see, for we have individual entities, 

 the chromosomes, that are distributed from cell genera- 

 tion to cell generation, from parents to offspring, in a 

 manner that coincides exactly with the behavior of the 

 individual character." 



We come now to consider the question of the trans- 

 mission of individual characters. There are some who 

 claim that the action of the environment will cause varia- 

 tion and different characters in the offspring. This prop-
