pasture. Otherwise, local irrigation of the cervix with hot i per 

 cent, lysol solution and application of Churchill's tincture of iodine, 

 or light application of the actual cautery to the lacerated and eroded 

 os, may be done. Dilatation of the cervix, when it is contracted, 

 and gentle curetting of its endometrium, followed by loose packing 

 with iodoform gauze, are also indicated. Daily warm lysol (i per 

 cent. ) injections should follow any operative measures. 



Muscular Rheumatism — Myalgia. 



This is a painful condition of the muscles and also of their 

 fasciae and periosteal attachments. It is commonly caused by ex- 

 posure to cold and dampness, and by toxins, and is difficult to 

 separate clinically from muscle strain or bruise. It is pathologically 

 ascribed to interstitial myositis or neuralgia of sensory nerves. All 

 animals are affected, but it is more frequent in horses, cattle and 

 dogs. 



Symptoms. — General stiffness in movement and soreness of the 

 affected muscle on pressure and movement, and shifting of lame- 

 ness suddenly from one part to another. The shoulder and lumbar 

 region are common seats. The affected muscles feel hard and tense

 fever may be present. 



Treatment. — The treatment is general and local. General 



treatment consists in warm covering and rest of the affected part ; 



in the use of a cathartic and the internal administration of some 



I 

 salicylic and iodide preparation. A physic ball, Glauber's salts 



and one to three compound cathartic pills may be given respectively 

 to horse, cow and dog. Sodium salicylate is administered to horses 

 and cattle in solution thrice daily in half-ounce doses. To dogs it 

 may be given in capsules in five to ten grain doses three times daily, 

 or, better, as the synthetic substitute, aspirin, in the same manner 

 and dose. Sodium iodide and sodium salicylate may well be com- 

 bined for dogs, gr. v of each in capsule ; for large animals, §ss of
