DISEASES OF CATTLE 79 



Treatment. The throat should be syringed three times a day 

 with an ounce of the following solution: Nitrate of silver, l 1 /^ 

 drams, distilled water, 1 pint. Bland and soothing drinks, such as 

 linseed tea or oatmeal and water, should occasionally be offered. 

 Diet should consist of soft food, such as bran mashes with a little 

 linseed meal mixed in them. Dry hay and fodder should be avoided. 

 Fresh green grass or sound ensilage may be fed in small quantities. 

 The upper part of the throat and the space between the jaws should 

 be well rubbed once a day with the following liniment: Liquor 

 ammonia fortior, 4 ounces; oil of turpentine, 4 ounces; olive oil, 

 4 ounces; mix. When evidence of blistering appears the applica- 

 tion of the liniment should be stopped and the skin anointed with 

 vaseline. Under the above treatment the inflammation of the throat 

 will gradually subside and the animal will be able -to swallow as 

 usual in five or six days. During its treatment the sick animal 

 should be kept in a comfortable stable. 



Mumps (Parotitis). Inflammation of the parotid gland may 

 arise from the inflammation extending to it when an ox is affected 

 with pharyngitis or laryngitis, or the inflammation may commence 

 in the salivary ducts and may depend on some influence the nature 

 of which is unknown. Parotitis sometimes arises from a blow or 

 contusion which is severe enough to set up inflammation in the 

 structure of the gland. Tuberculosis and actinomycosis may in- 

 frequently be characterized by the lodgment of their parasitic causes 

 in the parotid glands, in which case parotitis may be a symptom of 

 either of these diseases. 



Symptoms. There is an elongated painful swelling, begin- 

 ning at the base of the ear and passing downward along the poste- 

 rior margin of the lower jaw. The swelling is sometimes limited to 

 one side and when both sides are swollen it is generally larger on 

 one side than on the other. The secretion of saliva is increased, the 

 appetite is poor, the neck is stiff, so that it is painful to raise the 

 head, and food is swallowed with difficulty. In many cases the 

 swelling of those glands, when submitted to proper treatment, dis- 

 appears in a comparatively short time. In other cases, however, 

 the gland remains enlarged, even after the animal recovers its ap- 

 petite. In tuberculosis, lymphatic glands beneath the parotid glands 

 are sometimes enlarged thus causing the appearance of enlarged 

 parotid glands. 



Treatment. A warm bran poultice, made by mixing bran with 

 a hot 2 per cent solution of creolin in water, should be applied on 

 the swollen gland, maintained in place by means of a bandage. 

 Whenever the poultice has cooled it should be replaced by a new 

 one. This treatment should be continued until the pain is less and 

 the swelling is reduced or until there is evidence of pus formation, 

 which may be ascertained by examining the surface of the gland 

 with the fingers; and when, on pressing any part of the surface, it 

 is found to fluctuate or give, then we may conclude that there is at 

 that place a collection of pus. It is well not to open the abscess until 

 the fluctuation is well marked, as at this stage the pus or matter is
