DISEASES OF THE HOG. 179 



for the cause of disease. The lungs and stomach 

 had spots of congestion. All the other organs were 

 healthy. I treated the other seven with a dose of 

 epsom salts and a few doses of tincture of aconite, 

 but only one recovered, the others died during the 

 night. 



Treatment of Inflammation of the Brain : In the 

 early stage give a strong dose of epsom salts, two 

 ounces to the adult pig; follow this by giving three 

 to five drops of tincture of aconite if it does not 

 cause vomiting; if it does, it should be discon- 

 tinued. Ice to the head would be of service, but it 

 is impossible to apply it to the head of the pig. A 

 blister of cantharides to the back of the head may 

 be of use and should be tried. 



CHOREA. 



Chorea: This disease affects the muscles, caus- 

 ing involuntary contractions in some part of the 

 body. The contractions are not rigid or persistent 

 like those of tetanus, nor quick or jerking like 

 those of convulsions. They resemble somewhat 

 the voluntary movements. 



Causes: Defective nutrition has something to 

 do with this disease, as it is often less seen in ani- 

 mals of a feeble condition, some excitable state of 

 the nervous system or the nerves supplying a mus- 

 cle or a group of muscles. I have seen this com- 

 plaint affect pigs to all appearance in the best pos- 

 sible condition. It is therefore difficult to ascribe 

 a cause. It seldom attacks very young or very old
