these individuals are the cells, just as the builders of all 

 the different structures now used in war in their struggle 

 for national existence, are the human individuals. The 

 structures produced by cells or cell communities are all

 take, for instance, the common turtle with its armor plate 

 of bone, which in every way resembles a fortification.

 this moving fort we call the turtle.
