THE CELL AS A MICROBE 61 



ent kinds of species are brought into existence, 

 some to build the muscles, some the bones, some 

 the blood, some the skin, some the hair, some the 

 nervous system, some the heart, some the bowel, 

 some the liver, some the kidneys, some the lungs, 

 some the brain, and so on. While each kind of 

 cell, like each kind of microbe, works to build and 

 sustain a certain part, it also has in view the 

 higher aim so to fashion its own part in relation 

 to all the other parts fashioned by all the other 

 kinds of cells as to render all the parts, when fin- 

 ished, so suited to, and harmonious with, one an- 

 other as to make the complex body complete. 



The vital relation here seems to attain its high- 

 est point. A vital tie binds together as one life 

 the entire organism. The blood carries life to 

 every cell in the system. Puncture the skin at any 

 point with the finest needle, and the pain is in- 

 stantly telephoned through the whole being. If 

 one cell suffer, all suffer with it; if one cell re- 

 joice, all rejoice with it. 



Thus the cell has a true Evolution. So has the 

 microbe. With the Evolution of the microbe be- 

 gins the division of labor. Different species do 

 different kinds of work. With the Evolution of 

 the cell this division of labor is carried to higher 

 and higher degrees. The Evolution of the cell is 

 simply the continuation of the Evolution of the 

 microbe. The two^are one. Every cell is a mi- 

 crobe. Every microbe is a cell.
