Practical disinfection. In disinfecting stables, pens and 

 the like it is necessary first to remove all litter, which should 

 be burned or thoroughly soaked with a disinfectant and sec- 

 ondly, the floors and walls should be thoroughly cleaned to 

 insure its free access, after, which the germicide can be applied. 

 The thorough scrubbing of the floors and walls with a hot soda 

 solution will greatly enhance the efficiency of the disinfectant. 

 All cracks and crevices should be soaked to the bottom with 

 the disinfectant if a liquid is used and if a gas is chosen, they 

 .should be cleaned to enable its free access. Jaeger 1 has called 

 attention to the necessity of knowing the disinfecting power 

 of the agent used for the specific organism to be destroyed. 

 The failure to recognize this principle accounts for many 

 failures in practical disinfection.
