animal must be treated with cooling medicines, such as 2-ounce 

 doses of hyposulphite of soda, or 4 ounces of Epsom salts and £ 

 ounce of saltpetre, along with 3 ounces of aromatic cordials 

 (pay. 1019), which may be given night and morning in treacle gruel 

 until the bowels respond. 



811. When the dairy cow is affected, one or more of the quarters 

 may be attacked, either before or after calving j the udder becomes 

 hard and painful, with the teats pointed, and these, on being pressed, 

 yield a quantity of curdled milk and watery fluid. If the inflamma- 

 tion is not arrested at this stage, the complaint may go on until 

 matter is formed, or abscesses form and burst in various parts of the 

 udder, giving rise to great trouble. Again, the gland may become 

 hard and indurated, or even gangrenous. There is no complaint 

 that will, in such a short time, produce so much constitutional 

 disturbance and high fever, and cause the animal to lose flesh so fast, 

 as an acute attack of inflammation of the udder. The disease is 

 occasionally also accompanied with stiffness or lameness of the hind- 

 legs. Treatment.— -When first observed, and before matter is formed, 

 the affected quarters must be fomented with hot water for from 

 forty or sixty minutes four times in the twenty-four hours. Imme- 

 diately after the hot fomentations the parts must be washed well 

 with cold water for five minutes, and then rubbed perfectly dry with 

 a soft cloth, after which apply equal parts of carbolic oil and liquid 

 extract of belladonna ; cover up with cotton-wool and support with a 

 bandage round the loins and over the quarters. Or, immediately the 

 quarter is found to be hard and inflamed, all the watery fluid must be 

 drawn off through the teat, and the quarter should be treated with 

 an injection of 15 grains of chinosol dissolved in 1 quart of warm 

 water, and repeated if necessary. To be successful in preventing the 

 formation of pus, energy, perseverance, and patience are required ; 

 if, however, matter should form, it must be liberated, as already 

 shown. Constitutional disturbances are to be treated with the fever 

 medicines, as recommended for the grazing cow (par. 810). 



812. Induration. — When the udder becomes hard, applications 

 of 20 per cent, oleate of mercury, or iodine mercurial ointment must
