DISINFECTANTS, ANTISEPTICS AND DEODORANTS 693 



chlorine, they sometimes actually destroy compounds which 

 give rise to the stench. Sewer and other malodorous gases, 

 resulting from foul decomposing matter and excreta, may be 

 freer from bacteria than ordinary air, and are not usually 

 the carriers of micro-organisms, nor the cause of specific 

 infectious diseases. These gases do, however, occasion in- 

 definite symptoms of ill-health. Deodorizers, which are 

 also disinfectants, are of service in destroying noxious 

 emanations and their source ; but, to accomplish this, 

 it is necessary that they come into direct contact with 

 putrefying material, and should not be placed about the 

 habitations of man or animals, with the ridiculous idea 

 that they are achieving more than the production of a vile 

 odor. 



PRACTICAL DISINFECTION. 



The premises occupied by animals suffering from con- 

 tagious diseases, together with all articles contained therein, 

 such as harness, blankets, stable implements, and evacua- 

 tions, must be disinfected after the removal of all animals 

 and isolation of the sick. The excreta should be mixed with 

 milk of lime (1 part of freshly slacked quicklime, with 2 

 parts, by volume, of water), or with pure chlorinated lime. 

 The floors and walls must be scraped and washed. Boiling 

 water should then be poured over every available part of 

 the premises, and these brushed with a saturated solution of 

 chlorinated lime. Clothing may be treated by boiling in 

 water, or by soaking in a solution of corrosive sublimate 

 (l-500j, or carbolic acid (1-20), for twelve hours. Harness 

 is disinfected by washing with soap and water, and then 

 with a 2 per cent, crude carbolic or creolin, or 1-1000 corro- 

 sive solution. Valueless articles are given to the flames. 

 Stable and metallic instruments and fixtures are to be freed 

 fi'om dirt, scrubbed with soap and hot water, drenched with 

 boiling water, and then with a 2 per cent, crude carbolic or 

 creolin solution.
