214 CELL INTELLIGENCE THE CAUSE OF EVOLUTION 



stroyed before they multiply and get into the blood. Who 

 looks after this work? 



The cells of the body, which we call the white cells, are 

 cells that have not taken upon themselves any particular 

 work, like the cells of the muscles and nerves, but live as 

 separate beings in the body in the same manner as the 

 amoeba now lives in water. These cells have the work 

 of destroying invading armies of other cells, such as dis- 

 ease bacteria of all kinds, and also of repairing broken 

 parts. If you cut your finger, they will rush to the spot 

 in countless numbers and commence at once to close up 

 the cut. To do this they will sacrifice themselves, if nec- 

 essary, in destroying and fighting germs, trying to enter 

 the body through the cut. In the struggle for existence 

 it is necessary at times under certain circumstances for 

 one individual to sacrifice his life for others. It is done 

 by an intelligent being exercising his intelligence and 

 judgment in the matter on the theory that it is the best 

 that can be done under those particular circumstances. 

 Here we might also consider the fact that the body has 

 to do the best that can be done in each particular case, 

 for instance, if for some reason a broken bone in an animal 

 can not be healed, it will proceed to make a joint at the 

 place. I quote from Spencer : 



"But the most remarkable modification of this order 

 occurs in united fractures. 'False Joints' are often formed, 

 joints which rudely simulate the hinge structure or ball 

 and socket structure according as the muscles tend to 

 produce a motion of flexion and extension or one of rota- 

 tion. In one case according to Rotikonsky, the two ends 

 of the broken bone became smooth and covered with per- 

 iosteum and fibrous tissue, and were attached by liga- 

 ments that allowed motion, and in the other case the ends 

 similarly clothed with the appropriate membrane became
