DISINFECTION 409 



previously directed, or the floor washed with boiling water, 

 soap, and carbolic acid, in order to render the surface fit 

 for the penetration of whatever disinfectant is employed. 



It is in the scrubbing of wood and iron work, both of 

 fittings and doors, where the greatest supervision is 

 required, the out-of-the-way parts and places difficult of 

 access are forgotten, and in this way the whole value of 

 the work may be thrown away. 



Boiling water, soap, and carbolic acid must also be 

 applied to the wall over the manger, whether it be tile, 

 cement, or plaster. 



In this way the pores of the stable are open for disinfec- 

 tion, which may now begin either by the slow process of 

 washing the walls down by hand with a disinfectant, viz., a 

 solution of lime chloride, carbolic acid, or Izal, or preferably 

 by spraying these solutions over the entire surface as just 

 described. All windows and doors are left open for the 

 purifying effects of the free perflation of air, and the disin- 

 fecting action of sunlight. For safety the spraying process 

 may be repeated in two days' time. The stable or shed 

 may now be limewashed, the wood and ironwork painted, 

 and the building is fit for occupation. 



Where underground drains exist, these must be flushed 

 out with water and crude carbolic acid. In connection with 

 this, it may be noted that the most thorough application of 

 the disinfectant to the floor must be made. Most stable 

 floors afford thousands of nooks and crannies where patho- 

 genic material may lodge, and no effort should be spared to 

 thoroughly clean them out. 



Water troughs may be disinfected by scrubbing them 

 inside and out with boiling water, soft soap, and carbolic 

 acid. They are then thoroughly washed with a disinfectant, 

 and the process repeated three times for safety. 



The disinfection of leather work is generally unsatisfac- 

 tory, as most of the disinfectants rot it. A preliminary 

 scrubbing with soft soap and warm water should be given, 

 and the leather allowed to dry. It should then be scrubbed 

 with a 5 per cent, solution of Izal and this repeated. In
