advocated for mange; a preliminary cleansing followed by true 

 disinfection. 



Particular care is to be taken to see that all the bedding and 

 soiled food is destroyed. The water pot, or bucket, the hay rack, 

 manger, &c., call for special attention, scalding and scrubbing with 

 hot soda solution being a most useful procedure. 



The great point to remember is to make the place clean, and this 

 is the most difficult thing to get done. 



INFLUENZA AND PNEUMONIA. With such diseases as these, 

 in addition to the general measures it is advisable to dis- 

 infect the roof and air of the building. This may be done by 

 generating sulphur dioxide or chlorine gas as described on page 215. 

 It is important to bear in mind that such disinfection, or rather 

 attempted disinfection, is of no avail if the atmosphere in the 

 building is dry. A sufficiency of gas must be generated, 3 Ibs. of 

 sulphur being required for each 1000 cubic feet of air space. The 

 place must be completely sealed for twenty-four hours. Too much 

 reliance should not be placed on aerial disinfection, and in many 

 stables it is impossible to carry it out owing to the structure of the 

 roof. A thorough washing of the walls and as much of the roof as 

 can be done by means of the hose pipe is to be recommended and 

 lime- washing, the wash containing 5 per cent, of carbolic acid, 

 with a spray pump is advantageous. Aerial disinfection can then 

 be done as an aid to the other more useful measures. 



The casual burning of a few sticks of sulphur in a loose-box 

 while it may appeal to the layman does very little good. 



The author has adopted the following method as a routine 

 hospital practice for the disinfection of hospital boxes. The boxes, 

 which are faced throughout with smooth cement, are flushed out 

 with plenty of water and scrubbed with brushes ; when the place is 

 clean, the walls, floor, door, manger, &c., are scrubbed with a 

 solution of bleaching powder, 1 Ib. to a stable bucket of warm water, 

 the doors and windows are then closed for twenty- four hours, 

 after which the place is opened up and again scrubbed out with 

 plenty of water and then left to dry. The bleaching powder leaves 

 the place clean and fresh, and in the case of mange-boxes removes 

 the grease from the walls. 



DISINFECTION OF PIGGERIES. A piggery may require dis- 

 infection following an outbreak of swine fever, swine erysipelas, 

 anthrax, parasitic bronchitis, or other infectious malady such as 

 tuberculosis. When anthrax occurs in a piggery it must be dealt 

 with along the lines indicated on page 223. To what there has been 

 said it is only necessary, to add that the source of an outbreak of
