tions should be followed closely as given under Sheep Scab 

 Leet. XXVI. This dip is prepared as for sheep except that we 

 use twelve pounds of lime instead of eight pounds. 



Always treat the apparently healthy skin to a considerable 

 distance beyond the diseased border in case of small areas and 

 local treatment. 



Prognosis. — The prospect of recovery is good in recent cases, 

 but if the animal has been long and badly affected and the 

 disease covers a considerable portion of the body, then the pros- 

 pect is not encouraging. The Sarcoptic horse mange is much 

 harder to cure than common body scab of cattle, and may re- 

 quire three to five dippings at six to ten day periods, depend- 

 ing on the weather. 



Disinfection. — All structures which may have become con- 

 taminated should be thoroughly cleaned and disinfected. The 

 ooze or sediment made in the preparation of lime sulphur dip 

 will serve well for this purpose, or a 6 per cent solution of any 

 of the better coal-tar disinfectants may serve the same purpose.
