from diphtheria has been reduced over one half. Its 

 effects as a preventive measure and in lessening suffer- 

 ing "have everywhere been most significant and en- 

 couraging." Antitoxines for lockjaw, for snake bites 

 and for some forms of blood poisoning have been pro- 

 duced and are used with more or less success. 



Constant efforts are being made to find an available 

 antitoxine for every infectious disease. Many diffi- 

 culties present themselves, because the same germs do 

 not always cause the identical disease when introduced 

 into the bodies of the lower animals that they produce 

 in the body of man. 



SANITATION 



As sunshine and pure air are Nature's free disin- 

 fectants, their presence in the house is the greatest pre- 

 ventive measure of all sickness due to micro-organ- 

 isms. They, then, are the foundation requirements 

 for cleanness, because this means so largely the ab- 

 sence of dust-plants. 



Inside our houses there can never be the same 

 amount of sunshine and fresh air that proves so ef- 

 ficient out-of-doors. The house, too, must be dry, and 

 therefore dust cannot be held as it often is out of 

 doors on damp surfaces. However, the absence of 

 winds inside makes possible, after a little while, a com- 

 paratively dust-free air, because the heavier particles 

 which carry the bacteria and molds will settle on all 

 surfaces, chiefly on the horizontal ones, as floors,
