Practical Disinfection* 



The premises occupied by animals suffering from contagious 

 ■diseases, together with all articles contained therein, such as harness, 

 "blankets, stable implements, and evacuations, must be disinfected after 

 the removal of all animals and isolation of the sick. The excreta, 

 excrement and urine should be mixed with milk of lime (one part of 

 freshly slacked quicklime with two 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 avail- 

 able part of the premises, and these brushed with a saturated solution 

 of chlorinated lime. 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 : 5 per cent, formalin, 2 per cent, cresol, 

 1 to 500 corrosive sublimate, or 5 per cent, crude carbolic acid 

 solution. 



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 percent, 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. This is frequently out of the question, 

 however, on account of the size or open character of the stable. L,ive 

 steam is the most efficient means at our disposal for this purpose, 

 when a suitable apparatus for its application to woodwork, haymows, 

 etc., is obtainable. In place of this we may resort to formaldehyde, 

 chlorine or sulphurous acid gas. In using formaldehyde all openings 

 into the outer air should be closed as far as possible. Then 16^3 

 ounces of potassium permanganate should be added to each 20 

 ounces of formalin (or in this proportion) in deep tin vessels to avoid 

 the effects of frothing. This quantity of formalin and potassium
