Treatment — Long warts may be removed by twisting 

 or tying a silk thread tightly about the base of the growth. 

 The wart will eventually slough off. 



Repeated applications of glacial acetic acid or other 

 caustic to the body of the wart have been successfully used 

 in the removal of such growths. Care must be observed, 

 however, to restrict this treatment to the objectionable 

 growth, as these chemicals are very injurious to healthy 

 skin. As a precaution, the normal area around each wart 

 may be previously coated with petrolatum or tallow. A 

 safer treatment is to paint the warts with collodion con- 

 taining 15 per cent of salicylic acid. The collodion film is 

 removed every 3 days and the growth is recoated until it 

 finally sloughs off. The simple application of castor oil 

 at two-day intervals is also said to be effective in killing 

 warts. 



Some warts require surgery for their removal. In such 

 cases the after-treatment consists in painting the wound 

 once or twice daily with tincture of iodin until well healed. 



Tumors. 



Tumors in the teat or milk cistern may be harmless 

 growths, or simple connective-tissue enlargements due to 

 interstitial mammitis or to a degeneration of the gland ac- 

 companying age. As a rule these growths are better not 

 interfered with unless they become so large as to obstruct 

 the milk flow or otherwise inconvenience the cow. Some- 

 times they may be reduced by the persistent external ap- 

 plication of the tincture of iodin or an iodin ointment. If 

 their surgical removal becomes necessary it should be un- 

 dertaken only by one skilled in the principles of veterinary 

 surgery, and not until the cow has been dried off. Under 

 the most favorable circumstances, surgical treatment of the 

 udder involves the danger of a serious infection of the 

 organ. 



Tumors within the body of the udder, and sometimes 

 in the milk cistern, may be tuberculous. Such a suspicion 

 may be dispelled only by the animal's failing to react to the 

 tuberculin test. A tuberculous growth in the udder is be-
