816. Inflammation of the Udder in Sheep.— The ewe, par- 

 ticularly in frosty weather, suffers very much from inflammation of 

 the udder, especially when the teats are chapped and sore. The 

 derangement can also be produced when the young lambs are 

 affected with stomatitis pustulosa (par. 237), and aphtha, or thrush 

 (par, 236), and the inside of their mouths are ulcerated, and there- 

 from irritation and inflammation is set up in the teats and udders of 

 the mothers. The udder is much swollen and painful to the touch 

 and on pressing the teat a quantity of straw-coloured watery fluid 

 escapes. Treatment.— Good nursing, drawing the teats, and rubbing 

 the affected parts with the carbolic oil, are recommended. Hot 

 fomentations, if the parts are not thoroughly dried with a soft cloth 

 when finished, only aggravate the complaint. If the case runs on to 

 gangrene, the udder becomes, first red in colour, next purple, and 

 finally black ; and to guard against this, a careful examination should 

 be made twice daily. The lambs must be taken off, the ewe isolated 

 and carbolic oil or Stockholm tar smeared over the gland, the latter 

 being preferable. If the animal be left alone, it is astonishing to see 

 how soon Nature can assert her influence, the physiological action of 

 the healthy parts throwing off the diseased portions ; and in the space 

 of a few weeks the remains of the gland hang from the belly in the 

 form of long fingers of flesh, which can be removed by the clam and 

 hot-iron, the ecraseur, or ligature.
