be applied with the necessary care. Experiments are being- 

 made to determine more definitely the extent to which this 

 method can be applied with safety. 



The practical use of disinfectants is a matter requiring 

 much attention if good results are to be attained. It is not 

 wise to trust the disinfection of pens and stables to their own- 

 ers, unless they are men well versed in the knowledge of dis- 

 infection. The failure to properly disinfect stalls and stables 

 is frequently the secret of the failure to stop the ravages of 

 infection. 



In the employment of commercial disinfectants, it is 

 necessary also to know the destructive value of the solutions 

 for the organism to be destroyed. There are many so-called 

 disinfectants that, in the strength of the solutions recom- 

 mended, are little if any better than a poor antiseptic. In the 

 destruction of pathogenic microorganisms it is important to 

 ever keep in mind that the disinfectant must be able to kill 

 the organisms in the condition under which they are then 



existing.
