CHEONIC RHEUMATISM. 633 



an affection of the synovial membrane. In severe cases the affected 

 animal stands with difficulty, the limbs are much swollen, and the 

 regions of the joints are bulged out, soft, and puffy. 



The remedies for acute rheumatism should be speedy and ef- 

 fective. The use pi salicylic acid, with proper nursing, is recognized 

 as about the best remedy. The following formulas, in the order 

 given, are highly recommended by leading practitioners : —

Tincture of cantharides '.'.'. % . 2 oz. 



Tincture of opium -. 2 oz.

Chronic Rheumatism 



does not change its locality as often as the acute form. This form 



usually attacks a joint, and results in ulceration of the cartilage and 



the increase of bony deposit surrounding it. The lameness caused 



by chronic rheumatism is exceedingly obstinate, and yields only to 



long-continued treatment. It returns on the least exposure. There 



is little fever attending this form of the disease, and the general 



condition of the patient during the continuance of the disease may 



be good. Hot fomentations, fully explained on page 616, would 



be the simplest, speediest, and most effective method of relieving 



severe pain and inflammation. 



The following remedy may be safely employed : — 



Carbonate of potash 1 oz. 



Nitrate of potash •. 1 oz. 



Iodide of potash 2 dr. 



Give in a pint or two of water ; to be repeated once a day for 

 two or three days, and then omit a day or two, or lessen the amount.
