CHAPTER IX 



DIFFERENT KINDS 



IN the Visible World, as everyone knows, the Ani- 

 mal Kingdom is divided into two sub-kingdoms, the 

 Vertebrate and the Invertebrate; and the Vegeta- 

 ble Kingdom into two sub-kingdoms, the Flowering 

 Plants and the Flowerless Plants. But in the In- 

 visible World the Microbian Kingdom, as already 

 indicated, is divided into three sub-kingdoms, the 

 Spherical, Fig. 40, the Eod Shaped, Fig. 41, and 

 the Spiral Shaped, Fig. 42. And, like the sub- 

 kingdoms in the Visible World, the sub-kingdoms 

 in the Invisible World are divided into families, 

 classes, orders, genera, species, individuals, and the 

 individuals into endless varieties. Into these dif- 

 ferent kinds the infinite multitude of microbes may 

 be classified. No two are exactly and absolutely 

 alike. 



Likewise, in the Visible World, every kind repro- 

 duces only its own kind; man reproduces only 

 man; the lion reproduces only the lion; the oak 

 only the oak. So in the Invisible World the 

 Spherical microbe reproduces only the Spherical, 

 the Rod Shaped only the Rod Shaped, and the 

 Spiral only the Spiral. Through all the lower di- 

 visions of these infinitely small beings, also, each 



kind reproduces only its own kind.
