PREVENTION, SYMPTOMS AND TREATMENT ^ 



Treatment. — Treatment consists in casting the animal and re- 

 moving by the knife or actual cautery all of the diseased horn from 

 the sole of the foot, so as to fully expose the soft parts beneath. 

 Then the exposed tissue is dressed with one or more of the follow- 

 ing agents : Salicylic acid.; stick silver nitrate ; equal parts of alum, 

 or tannic acid, and iodoform; formaldehyde (10 per cent.) ; creolin, 

 or iodine ointment (5 per cent.) ; zinc, copper and iron sulphates, of 

 each equal parts, vaseline enough to make a paste, and creolin to 

 make 5 per cent. Then the foot is protected with tow, shoe and 

 leather or iron sole, and dressed daily with one of the agents noted 

 above for a week or more. After that time the dressings may be 

 done less often and applications of tar are made, or calomel. When 

 it is necessary to remove all the sole of the foot, hemorrhage may be 

 prevented by tight bandage about the fetlock, after the animal 

 is up. 



If the disease has invaded the sensitive laminae, treatment is 

 hopeless. If the canker spots appear during treatment they must 

 be cut away. In some cases it is well to work the patient after the 

 first few days of treatment. 



Cerebral Anemia. — Anemia of the Brain. 



This is always a secondary disorder due to weakness of the 

 heart (as in ordinary fainting), loss of blood, general anemia, com- 

 pression of brain from dropsy of ventricles, etc., fright, sudden 

 withdrawal of fluid from chest or belly, or of gas from bowels in 

 tympanites, causing rapid flow of blood to these parts. The com- 

 mon symptoms are sudden unconsciousness with almost or quite 

 imperceptible pulse, dilated pupils, and sometimes twitching of 

 muscles and vomiting. 



Treatment. — The head should be kept low and ether (H., 

 §ss; D., TlXxxx, undiluted) or aquae ammoniae (H., 3ii; D., TTlxv, 

 undiluted) should be injected into the muscular tissue to cause 

 rapid stimulation. At the same time strychnine (H., gr. ii; D.,
