THE LIVING STRUCTURES 163 



who are the general caretakers of the body, whose duty 

 it is to look after everything- in general, such as the fight- 

 ing of bacteria and disease germs and the general repair 

 work, will sacrifice their own lives by thousands if neces- 

 sary to save the body. They live in the body enjoying 

 complete liberty. They do not float in the blood stream 

 except when in a hurry to get somewhere, but move 

 around everywhere as separate independent beings to see 

 that everything goes right. If a bruise or cut happens 

 they are at once informed in some way. We do not know 

 just how, but they rush to the spot by thousands and 

 direct the repair work and if necessary they change their 

 own occupation and take a different job, that of making 

 connective tissue in order to bind the tissues together. 

 In nearly every open sore, bruise or cut, they are killed in 

 great numbers in their faithful efforts to repair and close 

 up the wound. A text book on physiology briefly speaks 

 of it as follows : 



"When the skin is injured the white blood cells form 

 new tissue upon the surface, while the epithelium 

 spreads over it from the edges, stopping the growth and 

 completing the healing processes." 



There seems to be no particular center in the body 

 around which intelligence revolves. Every cell seems to 

 be a center of intelligence and knows what his duties are 

 wherever he is placed and wherever we find him. Every 

 citizen of the cell republic is an intelligent patriotic be- 

 ing. It is a democracy where every individual enjoys an 

 intelligent independent existence, and all are working 

 together for the welfare of all. Nowhere can we find 

 more absolute sacrifice of the lives of the individuals to 

 the general welfare of all than we do in the cell republic. 

 The results cannot be obtained in any other way nor at 

 any less cost of individual sacrifice, so it is necessary to
