If the disease has advanced further and there is already 

 active inflammation in the gland, foment continuously with 

 warm water, or support in a poultice, cutting holes for the teats, 

 adding a little belladonna to relieve the pain. Give an active 

 purge (salts) and follow up with aconite and nitre. Draw off 

 the milk frequently, using a milking tube if the act is very 

 painful. If the discharge smells sour inject a weak solution of

carbonate of soda and permanganate of potassa (5 grains of 

 each to i oz. of water). If the gland becomes hard and in-

 ensues, use lotions of carbolic acid or chloride of lime. Many 

 sheep do well with a coating of tar on the gland. In the 

 advanced stages nourish well and give tonics (sulphate of iron, 

 gentian, colamba). 



IMPERVIOUS TEAT. 



From concretions from the milk, which are freely movable 

 in the teat and up into the gland. From polypus in the teat 

 hanging by a band from the mucous membrane, and hence 

 movable only in narrow limits. From thickening of the mucous 

 membrane and contraction of the walls of the duct to absolute 

 closure. From the formation of a membrane across the duct 

 of the teat. From closure of the external orifice of the teat 

 effected in the healing of a sore. 



Treatment. — Concretions may be extracted by manipulation 

 or with a grooved director, the teat having been first relaxed in 

 a warm solution of belladonna. Polypi are removed by making 

 a free incision through the teat, twisting off the tumour, accur-
