sometimes finding a greater and sometimes a lesser 

 variety. 



Where the power of the bacteriologists should avail 

 much they are powerless. They may have the advan- 

 tage when they have the germs planted in incubators, 

 but in the human system it is different, and the germs 

 enjoy the change; for, in experimental work, these 

 germs have been passed back and forth so many times 

 from guinea pigs, rabbits and white rats that life began 

 to be a burden, but buried within the hidden recesses 

 of the human body they can enjoy life in spite of the 

 bacteriologists and their theories. 



Are the bacteriologists theorizing? Let us see. 

 Human blood contains many small bodies or particles 

 of matter called corpuscles. Vast numbers of these 

 float along with the blood-stream. There are two prin- 

 cipal varieties, red and white. The red possess great 

 power to absorb oxygen, and in their passage through 

 the lungs they absorb oxygen from the air we breathe, 

 and through the circulation carry it to different parts 

 of the body. The oxygen aids in the changes which 

 are constantly going on in the human system ;^ids that 

 form of digestion carried on in the circulation. The 

 oxygen gives life, force and energy. It is these cells 

 or corpuscles which give to the blood its bright red 

 color. 



Bacteriologists tell us that the white corpuscles act 

 as a body-guard ; they are a standing army for the pur- 

 pose of protecting the body from invasions from with- 

 out, and that when germs attack the system these 

 white corpuscles are greatly increased in numbers; the
