lesions throughout th-e body and the uniform presence of the 

 bacterium in the lesions indicate that no part of the body and no 

 secretion can be considered as free from infection. All parts 

 of the body, all expectoration, saliva, faeces, urine, milk even must 

 be withheld from all other animals, at least until they have been 

 thoroughly cooked or disinfected. Manure must be burned, or 

 buried deeply in quicklime. Contaminated pens, yards, wallows, 

 streams and fields must be abandoned or thoroughly disinfected. 

 Galtier found that the virus remained active for six days in 

 putrefying organic matter at 39 to 75 F.; in 25 days in water, 

 at room temperature ; the refuse litter, fodder, manure, and drain- 

 age matter from the infected place must be carefully guarded 

 against. The virus steadily loses in force in such media, but 

 remains infecting to animals injected with it. The most active 

 disinfectants may be used on the pens and yards (copperas 5$ , 

 sulphuric acid 2% solution, or mercuric chloride .i'/'c ) while the con- 

 taminated fields should be abandoned for the season. All drop- 

 pings may be treated with sulphuric acid (2%), creolin, lysol, 

 pheuic acid or copper sulphate. The susceptibility of practically 

 all the animals of the farm, demands the exclusion of these, while 

 that of rodents, renders necessary the further exclusion of wild 

 mammals ; and we may add birds, wild and tame, and if possible 

 flies. The plowing of the contaminated soil will do much to obviate 

 danger, yet the sheep folds and pastures should be separated by a 

 considerable distance from any place where infected animals and 

 objects have been. If drinking troughs for sound animals have 

 been used by the sick or suspected they should be emptied and 

 washed with a disinfectant (sulphuric acid 2:100).
