the perfect running, rooting and fighting machine which 

 will be required in a rough and tumble existence with the 

 elements and enemies that he will meet in the forest. 

 The cell whose wisdom must look after these details for 

 the hog will do the same for man, if he should be com- 

 pelled to hustle for himself in a wild forest. Man would 

 also be compelled to revert back to his savage ancestral 

 type. The cells, like man, will build such structures as

 is able to push the food around and between the teeth,

 air, but in order to be able to hear the ear drum must 

 always be strung up to a certain degree of tension ; if not 

 kept just so, you cannot hear. Who looks after these de- 

 tails? We find in every place in the body that every
