DISINFECTANTS, ANTISEPTICS AND DEODORANTS 725 



freer from bacteria than ordinary air, and are not usually 

 the ca,rriers 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. 



PEACTICAL 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 

 (1-500), 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 acid or creolin, or 1-1000 

 corrosive solution. Valueless articles are given to the 

 flames. Stable and metallic instruments and fixtures are to 

 be freed from dirt, scrubbed with soap and hot water, 

 drenched with boiling water, and then with a 5 per cent, 

 crude carbolic acid or creolin solution. 



Gaseous disinfection is now in order to kill micro- 

 organisms in remote and inaccessible places. Live steam 

 is the most efficient means at our disposal for this pur- 

 pose, when a suitable apparatus for its application to 



* Or all available parts of infected stables should be saturated with one of the 

 following solutions by means of a small hand force-pump, or brush : 8 per cent, 

 .ormalin, 1 to 500 corrosive sublimate, 3 per cent, cresol, or 5 per cent, carbolic acid.
