272 THE INVISIBLE WORLD 



dividuals, should, and does, have a corresponding 

 phylogenetic defense, or defense in the nation. 



Accordingly, the individuals of every well de- 

 veloped nation consist of two classes, civilians 

 and soldiers. The civilians do all the arts of in- 

 dustry ; the soldiers form a standing army for pro- 

 tection. 



The correspondence is perfect. In the body the 

 red corpuscles are the civilians; the white corpus- 

 cles the soldiers. The individual is to the nation 

 what the corpuscle is to the body. So perfect is 

 this relation that the ratio between the protecting 

 and the working forces in the body and in the na- 

 tion is practically the same. 



As already stated, the number of white corpus- 

 cles in the blood of the average adult is 81,250,- 

 000,000; and the red corpuscles, 32,500,000,000,- 

 000. This is exactly as one to four hundred, one 

 soldier microbe to four hundred civilians. 



Now take the seven best developed nations, 

 England, Germany, France, Italy, Russia, Japan, 

 the United States. As near as can here be cal- 

 culated, the average number of soldiers, during the 

 last decade or so, in the standing armies of the 

 seven nations, is 2,374,000. Their civilian popula- 

 tion, 950,947,000. Practically, one soldier to four 

 hundred civilians. In each case the ratio is the 

 same. In each case it is Nature's defense. 



When the evolution of Man shall attain a cer- 

 tain degree of perfection, he will, no doubt, be able 

 to conquer all disease germs, and keep them out of
