simultaneously or more frequently in turn. In addition to the hot, 

 tender and swollen joints, there are apt to he complications — as 

 pleuritis, pneumonia, endocarditis, peritonitis and sometimes 

 laryngitis. A subacute and chronic course oftens follows, with con- 

 tinued lameness and deformity of the joints, atrophy of the muscles, 

 and loss of condition. Acute articular rheumatism affects cattle, 

 dogs, horses, pigs and goats. 



Treatment. — Salicylic acid in some form relieves the pain and 

 fever, and alkalies are thought to prevent endocarditis. Sodium 

 salicylate may be given in ounce doses to the larger animals in solu- 

 tion thrice daily with an equal amount of potassium or sodium 

 bicarbonate. To dogs, the sodium salicylate may be administered 

 in tablets or capsules (gr. x to xl thrice daily). Or in the follow- 

 ing prescription: ^ Sodii salicylatis,, potassii bicarbonatis, aa 3v; 

 aquse gaultherise, ad oviii; s & l to 3 teaspoonfuls thrice daily in 

 water. When the salicylates cause anorexia, nausea or vomiting in 

 dogs, salol and phenacetin may be prescribed in capsule, of each 

 gr. v-x thrice daily, or aspirin in doses of 10 grs. given in the same 

 manner, is an excellent substitute. 



Local treatment consists in the application of methyl salicylate 

 to the joints and covering them with absorbent cotton-and bandage, 

 or in the use of cloths soaked in a hot saturated solution of epsom 

 salts and covered with waterproof protective and bandage. In the 

 later subacute and chronic stages, a combination of equal parts of 

 sodium salicylate and iodide is beneficial, given in solution thrice 

 daily (large patients, of each gss ; dogs, gr. x of each in solution or 

 capsule). Iodine ointment rubbed into the joints -and blistering or 

 firing are useful in the chronic form. Rest, warmth, and liquid 

 diet are indicated at the beginning ; milk for dogs and gruels or 

 mashes for large animals. In the later stages,, codliver oil, iron, 

 arsenic, bitters and good feeding.
