286 DISEASE,-- (li- CATTLE. 



ai'tiun is alreiuly somewhat impaired by the lesi(Jiis which have at- 

 taclved it. Ill this ease one-half ounce doses of potassium nitrate or 

 bicarbonate may Ijc given three times a chiy. Besides the constitu- 

 tional treatment, it may be necessary to give special attention to the 

 bowels in order to relie^'e constipation. Cattle may be given saline 

 laxatives at the outset, such as 1 pound of Epsom salt for an ordi- 

 naiy-sized cow, and the bowels kept regular by an occasional smaller 

 dose. 



In chronic rheumatism the best course of treatment is to give tonics 

 and local treatment. Loeal treatment may also be advisable in acute 

 rheumatism in addition to the constitutional treatment already pre- 

 scribed. 



External treatment depends solely on the local conditions and 

 should be applied judiciously. Among the various remedies may be 

 mentioned hot or cold moist packs, hot air and vapor baths, friction, 

 etc. Anodynes are often applied locally with good results. Blisters 

 are occasionally indicated. As anodynes may be mentioned liniments 

 and ointments containing salicylic acid or sodium salicylate in com- 

 bination with laudanum, aconite, or chloral hydrate. Camphorated 

 spirit, soap liniment, and essential oils also afford some relief when 

 applied locally. Of blisters, those containing cantharides are most 

 effective.
