the animals in a sound and healthy state, 

 having had no intercourse, either direct or 

 indirect, with the tainted cattle, and which he 

 will he careful immediately to isolate and keep 

 apart. 



A second class must he formed of those 

 heasts, which, though as yet unaffected with 

 the distemper, have, nevertheless, been ex- 

 posed more or less directly to its contagion, by 

 living and consorting with them, or by their 

 contact with other animals, either at fairs or 

 markets, or in the ships and cattle-trucks on 

 the railway during their transit from one place 

 to another. The horned cattle composing this 

 latter class must be carefully watched, and be 

 made the subject of the preventive treatment, 

 the moment the first sign appears of the 

 working of the incubation. 



A third class must be formed, consisting of 

 cattle actually smitten with the distemper. 



These divisions of animals being thus 

 settled and separated, will diminish the la- 

 bour and the cost of treatment and the 

 liability to diffuse the complaint, especially 

 when the epizootia begins to lose its viru- 

 lence.
