DISEASES OF HORSES AND CATTLE. 193 



to move, and if it does, it is with great difficulty. 

 On examination one or more of the joints will be 

 very painful. There may be no swelling, but 

 usually there is. The joints most frequently af- 

 fected are the stifle and fetlock. The hock and 

 hip less so. The swellings, when occurring, are 

 usually between the tendons, and if in the hock 

 joint may be taken for bog spavin. The pain con- 

 tinues, it may be, only for several hours, or it may 

 be for several days, when all at once in some un- 

 accountable manner the pain and swelling become 

 reduced or may entirely disappear, to shift to some 

 other joint or limb, and so on until it may disap- 

 pear altogether. These local symptoms are gen- 

 erally accompanied with more or less fever and a 

 decided rise in the temperature. The pulse is 

 from sixty to seventy per minute and the breath- 

 ing somewhat increased. 



Treatment: For this form of rheumatism I find 

 that a good dose of physic is useful, and the best 

 is one pint of raw linseed oil and twenty drops of 

 croton oil. This is for both horses and cattle. 

 Follow this by giving nitrate of potassium half- 

 ounce doses three times a day in the drinking wa- 

 ter. If the pulse is fast and full, give tincture of 

 aconite in twenty-drop doses every two hours in a 

 little water. After several days, if there is no im- 

 provement, give dram doses of iodide of potassium 

 three times a day with half an ounce of wine of 

 colchicum. When all fever has subsided, Fowler's 

 solution of arsenic in half-ounce doses twice a day 

 in bran mash is often very useful.
