396 Diseases of Swine. 



wise die can be cured by medical attention, and we are certain 

 that the progress of the contagion can very often be checked 

 in a herd by the same means. 



Let us suppose that what we have described as the predis- 

 posing causes have been carefully removed, and we turn to 

 look for an agent to check the development of the virus. 

 There are two such which present themselves with very large 

 and positive testimony to their value. They are sulphate of 

 iron (green vitriol, or copperas) and chlorate of potash. 



The sulphate of iron is at once the cheapest and the most 

 effective of the iron salts used in veterinary medicine. It is 

 antiseptic, and vitally invigorating ; and it has been proven 

 to have a specific effect in increasing the firmness of the 

 spleen and hastening the chemical changes of the blood. 



Without any knowledge of these properties, it is the chief 

 and almost only important agent in most of the receipts 

 which have been found actually efficacious in the disease of 



hogs which we are describing. Thus, one " infallible remedy," 

 given by a Kentucky farmer, is — 



No. 440. Sulphate of iron, 1 lb. 



Warm water, 3 gallons. 



Apply milk- warm to the skin of the affected animal, by repeated 

 sponging or mopping. 



A somewhat celebrated recipe of Prof. J. B. Turner, of 

 Illinois, is — 



No. 441. Flowers of sulphur, 

 Sulphate of iron, 



Madder, ^ of each, 2 lbs. 



Black antimony, 



Nitrate of potash, of each, J lb. 



Arsenic, 2 oz. 



Mix with 12 gallons of slop, and give a pint to each bog, this quan- 

 tity being for 100 hogs. 



Another, from the same authority, is —
