136 SPECrAL CATTLE THERAPY 



The most important point as regards the treatment 

 of variola in cows is the observation of cleanliness and 

 g'entle manipulation of the teat in milking. If the 

 teat contains a great number of vesicles a milking 

 tube should be used. 



Scab formation can be hastened by touching the pits 

 with a saturated solution of potassium permanganate. 

 If extensive ulceration occurs, the parts are to be 

 painted after each milking with a mixture of one part 

 tincture iodin and three parts tincture benzoin com- 

 pound. The number of cases in an outbreak can often 

 be limited if cows affected are milked last, thus avoid- 

 ing direct transmission of the disease.
