once, on the spot, plunged for 12 hours in a 5 per cent solution 

 of carbolic acid, or cresyl, or creolin or in a 2 per cent solution 

 of sulphuric acid, and, if the knives and other instruments used 

 are placed in boiling water for half an hour. The same will 

 apply to fleeces. 



Disinfection. All litter, fodder, manure, urine, and other ex- 

 cretions, or products ; all stalls, feeding troughs, sheepfolds 

 covers, halters, harness, wagons, poles, shafts, and other ob- 

 jects used about the animals, or soiled by them or their products, 

 should be disinfected by burning, flaming or scalding (boiling), 

 when applicable, by one of the above disinfectants, by mercuric 

 chloride (5:1000), by formalin, or other potent antiseptic. Ex- 

 tensive dungheaps, too wet to burn, may be sprinkled freely 

 with strong mineral acids, or mercuric chloride . in solution, 

 piled in compact mass, covered with chloride of lime and finally 

 with a thick layer of earth, and fenced in from all stock. 



If carcasses must be moved to the grave, rendering works, or 

 elsewhere, they should be sponged with carbolic acid solution, 

 formalin, or mercuric chloride, and each of the natural openings 

 firmly plugged with tow or cotton soaked in the same material, 

 so that no infecting mattei: may drop on the way. They should 

 on no account be dragged on the ground, but carried on a wagon 

 or stoneboat, which should be afterward carefully disinfected. 

 Men or animals, entering an infected place, should be disinfected 

 on leaving : especially hands and feet. 



All roads, yards and pastures, where the sick have been, and, 

 above all, where manure, saliva or urine has fallen, should be 

 subjected to thorough disinfection, or the surface layer removed 

 and deeply buried. When available a concrete or asphalt floor 

 should be placed in the buildings. 



Isolation. Movement from Infected Ground. It has long been 

 known that the movement of an infected herd from the con- 

 taminated pasture to another, will often at once check the de- 

 velopment of new cases. In Sardinia and Auvergne the flocks 

 and herds were yearly moved on the approach of autumn, from 

 the rich valley, and bottom lands, to the drier hill pastures, to 

 avoid or lessen the decimation that otherwise inevitably overtook 

 them. This is in keeping with the enzootic nature of the 

 malady which arises more from the microbe preserved in the
