KINDS OF GERMS. 



covering may be formed. The particles in Fig. 1 3 

 are only represented in outline. 



The minute germs developed in infusions in closed 

 vessels are represented in Figs. 17 to 20, plate III. 

 These are referred to in page 49. But the somewhat 

 definite characters manifested by these particles last 

 mentioned, are not exhibited by the most minute 

 germs discovered by the aid of the highest powers. 

 These, like the most minute particles of other kinds 

 of bioplasm, always appear as little specks of a 

 rounded form. There is no possibility of identifying 

 the different kinds of bioplasmic matter under the 

 microscope. The most minute living particles of a 

 vegetable organism exactly resemble those of an 

 animalcule or those which may become developed into 

 beings still higher in the scale ; and in another part 

 of this work it will be shown that these cannot be dis- 

 tinguished from particles of bioplasm derived from the 

 living mucus y or pus, or white Mwd'-corpuscles of man 

 himself. Every kind of bioplasm at this stage of its 

 being exhibits, as far as has yet been ascertained, pre- 

 cisely the same characters. 



Of Germs of different kinds of Vegetable Organisms. 

 Of microscopic fungi and algae there are many dif- 

 ferent kinds, which grow and multiply under very 

 different external conditions, and live upon different 

 kinds of food. Thus there are germs of numerous 

 different species diffused through the air and wafted 

 long distances at different seasons. Some flourish at
