ARE WORLDS INHABITED 269 



billions of billions of little living creatures which 

 float in the air thicker than motes in a sunbeam, 

 that swim in the waters so abundant that there 

 are millions in a raindrop, that penetrate all veg- 

 etable and animal substance and organisms, that 

 course through the veins of our bodies by the billion, 

 and eat our food for us that we may digest it 

 better ; yet in other suns and worlds produce no such 

 results? I cannot think so. 



The animalculae are so small that Ehrenburg 

 estimates that five hundred million of them exist 

 in one drop of water one twelfth of an inch in dia- 

 meter; that not only the blood, but the flesh and 

 muscles are also composed of infinitesimal lives, each 

 cell possessing a distinct life of its own. 



Binet describes man as a colony of protozans; 

 and according to these two biologists he is a walk- 

 ing Chinese Empire, when you consider the micro- 

 scopic beings in his body. Besides our bodies and 

 those of vegetable and animal organism that are 

 thus honeycombed and flooded with animalculine 

 life, there are countless millions floating in the air, 

 swimming in the water, and buried in the dust of 

 the earth. 



So that organic life is everywhere present on 

 the earth, in invisible or visible form. And the 

 invisible forms of life of the earth everywhere sur- 

 passes the visible forms millions of millions of times. 

 Just as the invisible matter in the world and the 

 universe surpasses the visible countless billions of 

 times. Thus the natural, spontaneous production 

 of life and life forms in myriads everywhere on this 

 earth emphasizes the reasonable hypothesis that 

 they are evolved on all suns and planets.
