lessened as to caiise the horse to breathe with difficulty. The 

 pulse, if altered at' all, is a little weaker than nsnal, the appetite 

 remains' normal as a rule, although at times the animal will have 

 difficulty in mastication. The temperature at first is normal, but 

 in a few days it may have reached 103°, 103°, or 104°. 



Over the surface of the sMn covering the swollen parts we 

 find a slight serous sweating, which loosens the epidermis and 

 dries, giving it the appearance of an eruption of some ctitaneous 

 (skin) disease. If' this is excessive we may see irritated spots, 

 followed by suppuration. This suppilration may become exces- 

 sive from the great distension and loss of vitality of the skin. 



Colics may sometimes occur during the course of this disease. 



The dung is ordinarily coated. ^ 



Later the pulse may beat 60 to 80 times per minute. 



High temperatures indicate complications. 



The mortality is about 50 per cent. 



Trea tment. — Place the patient in a clean, well-ventilated, roomy 

 box stall, the halter and surcingle must be removed; give sloppy 

 food, clean hay, and green fodder if possible, and plenty of fresh 

 pure water to drink. 



When the legs and parts of the body are covered by the dried 

 serum the surface naust be softened by the application of cosmo- 

 line, to which may be added a small amount of creolin (1 to 50) 

 or of carbolic acid (1 to 25). 



If sloughing has taken place, the sores must receive surgical 

 attention; dead tissue must be removed and antiseptics applied, 

 such as creolin, or bichloride of mercury, or carbolic-acid solu- 

 tions. 



If the animal has great difficulty in breathing, we must resort 

 to the use of the tracheotomy tube. 



Give tonics to increase the appetite and try to sustain the 

 strength of the animal. Spirits of turpentine, 3 to 4 ounces, given 

 daily, will have a beneficial effect by stimulating the heart and 

 kidneys; sponge the head, where swollen, with either ice-cold or 

 very warm water; repeat this several times daily. 



AZOTUEIA — HEMOGLOBINEMIA. 



Azoturia is not a disease of the kidneys. 



The principal cause of azoturia in the horse is the action of 

 cold. An abnormal sensitiveness to the action of cold is acquired
