infectant for heavy clothing because it does not penetrate 

 much beyond the surface. Thin articles of clothing may be 

 effectually disinfected by exposing them to bright sunlight for 

 a few days, and even heavier articles, by long exposure to 

 sunlight and air, will in time be satisfactorily disinfected. 



Thick, heavy articles of clothing or bedding cannot be prop- 

 erly disinfected by any means at our disposal. There seems 

 to be no satisfactory way of disinfecting mattresses, and, in 

 cases of exceptionally contagious diseases, the only proper 

 method of treatment of such articles is their complete de- 

 struction by burning. 



The Stable. The disinfection of the stable is not infrequently 

 demanded of the agriculturist. Such disinfection is difficult 

 because of the roughness of the lumber with which the stable 

 is made. A satisfactory method of disinfection is as follows : 

 First remove all dirt from all surfaces in the stable. This 

 must be done thoroughly or the disinfection will not be com- 

 plete. Water must be used freely to moisten up the dry filth 

 that has accumulated in various parts of the stable. The re- 

 moval of the dirt is thus facilitated, and the cleansing must be 

 thorough. After such cleaning, the whole stable should be 

 washed with a solution of corrosive sublimate, above given 

 (1-1,000). This maybe done by simply washing with a broom, 

 or better, by spraying, provided a proper spraying apparatus 

 be at hand. It must be remembered, however, that corrosive 

 sublimate corrodes metals badly, and no metal spraying appa- 

 ratus can be used. After the thorough wetting down of all 

 surfaces of the stable by the disinfectant, the stable must again 

 be washed with water to remove the disinfectant. Instead of 

 corrosive sublimate, a strong solution of chloride of lime may 

 be used in the same way in washing the walls and floors. 

 Such a disinfection, if thorough, will usually be found satis- 

 factory.
