136 SPECIAL 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.
