 without treatment, the manipulations during milk-

If this condition is recognized early, the teat

 before treatment is well applied it is then well to 

 use an antiseptic solution such as germicidal discs 

 in solution of 1 to 1,000, filling cup with the so- 

 lution and then holding against the udder al-

 from the loss of the liquid which it ordinarily 

 contains, can often be moved up and down in 

 the milk duct of the teat and often removed. If
